@ElectricityTaster 4 года назад

Maybe you can melt parafilm and make it flow in a laminar fashion.

@mellamobob 6 лет назад

I'm a software engineer, but my mom used to work in a lab. So I love parafilm. I once used parafilm to mend a violin bow I snapped right before a concert. I still carry a folded piece of parafilm in my wallet.

@AlexDainisPhD 6 лет назад

It's a useful thing to carry!

@JohnSmith-fj3uf 2 года назад

Parafilm is often used to wrap plant grafts. The scion, ( dormant twig with desireable fruit or flowers) is cut at the base in a way matching the cut on the rootstock (= tree you are grafting the scion onto). the scion away from the rootstock is commonly wrapped in Parafilm with a strip a few inches long hanging free. Then the cut end is attached and the Parafilm wrapped around it to both mechanically hold the twig in place a little and prevent dehydration before the bark grows together. When the connection is made buds grow through the Parafilm. Best to have it only one layer deep with some two layer overlap and shade graft till buds break through so it does not overheat....Many ways to graft this is only one.

@BushImports 4 года назад

The only thing I've ever seen it used for is tree grafting and wrapping the buds on a cutting that is either going to be rooted or grafted to something else to keep them from drying out. I can't believe it's used to all that other stuff. I learned something ,thanks.

@matteowildfishing5066 6 лет назад

Parafilm is my antistress in the lab! I'm in love with it! :D

@alexandrastar2697 6 лет назад

I have used this very successfully to seal perfume bottles before shipping. I make sure the crystal or glass stopper is turned well in until it stops. Then I take a Parafilm strip about 1" x 3" long, start stretching it at one end, and then holding the stretched end against the perfume bottle, slowly start winding and stretching all the time, round and round the place where the stopper and the neck meet, and even over the top and back around the neck. When I am near the end of the strip, I pull it down against the bottle so that the receiver can find the end. Magic! Even if the bottle leaks a little bit, the Parafilm holds the liquid and it doesn't escape and spoil the bottle's label. I was able to buy precut strips from Germany, but any will do.

@mversantvoort 6 лет назад

Glad you’re back! I never heard of parafilm before, it seems incredibly useful in the lab.

@jhongfrancisco2974 5 лет назад

Cactus collectors love this!

@AlexDainisPhD 5 лет назад

Really?! How is it used? I love finding out new ways people use parafilm :)

@Soonjai 6 лет назад

Until now I didn´t even know that Parafilm exists and I somehow already love it.

@nubsack6142 2 года назад

I'm doing some fruit tree cloning. I went to my local garden center, asked the lady if they had Parafilm and she looked at me like I was crazy lol. Not sure where to get this stuff locally aside from buying it off amazon.

@hugueslefebure9107 Год назад

Fungi Perfecti from Paul Stamet use to have it.

@Jpriest13 3 года назад

Using as a clearer residue free substitute to tape for masking clear parts prior to painting for plastic models. i.e. Aircraft canopies.

@gregzebarth4721 6 лет назад

Nice to see you post something again. I was just going over your old videos the other day as I missed having new ones.

@AlexDainisPhD 6 лет назад

There are more new ones coming! I have a couple already filmed an on their way to being edited. Grad school has been... overwhelming lately, but my videos are coming back :)

@Watchman999 4 месяца назад

slowly but surely I am sealing all my closed whisky bottles with an extra layer of protection using this.

@MrMawnster 3 года назад

It's so awesome! Used to use it in the chem lab. I use it now for grafting plants too haha

@qwmf05gcpt42 6 лет назад

We missed your channel. This is what should be in RU-vid rewind. I did not get this in my sub box saw from your reels video.

@bortmaximus 6 лет назад

Parafilm is magic. I don't remember ever ordering any but there was always plenty there. Instead of, like, a Bag of Holding, Parafilm was like a Box of Giving.

@AlexDainisPhD 6 лет назад

This is true! I did realize while filming this however that because the rolls they come in are endless, most of the Parafilm in our lab was likely... very old. There was a noticeable difference in "stretchability" between our (likely *decade* old...) Parafilm and the new box that came in!

@azdgariarada 6 лет назад

Welcome back. It's always a pleasure to see your videos!

@sullivannick 6 лет назад

I found my way here because of Smarter Every Day on Patreon. Great video - now I'm checking out your whole channel!

@AlexDainisPhD 6 лет назад

Welcome!!

@medcologytutorials2636 6 лет назад

Wow after a long time we are seeing you back.

@pragyaagrawal 6 лет назад

It was nice to know about a thing we use everytime in lab but knew nothing about. Thank you!

@Heimsendir Год назад

Hope you are well, just started using parafilm for my mycelium agar plates, so it was interesting to learn more about!

@RayAdamsCanada 3 года назад

I was looking for piece of information about what parafilm is; but then I become a parafilm school graduate. Thank you 🙏.

@AlexDainisPhD 3 года назад

Hahaha this is one of my favorite comments eve! I hope it was helpful!

@RayAdamsCanada 3 года назад

Yes. Indeed. Priceless.

@zsoltsemperger5276 6 лет назад

You're finally back!!!

@AlexDainisPhD 6 лет назад

And I have more videos coming!

@snapdazzlex 6 лет назад

Man how exciting - parafilm isn't cheap I reckon you saved your lab some money there ;) i love having a tiny piece and stretching it out as far as possibel!

@hugueslefebure9107 Год назад

You gotta have the right temp.

@AidynNichi 6 лет назад

I love parafilm! I want to get a pack myself for home use cuz it's so handy in the lab 😂

@zerg539 6 лет назад

Parafilm is the greatest thing for covering stuff in the lab if they made it in 18 inch wide straps I'd buy it instead of saran wrap. Also great to see a new video out of you I was starting to wonder if you had given up on youtubing

@AlexDainisPhD 6 лет назад

THEY DO! I didn't know it until this video: Look at the big blue box that Andrew pulls out around 1:35. That's a 20 inch wide roll!

@zerg539 6 лет назад

Alex Dainis ash I missed that because I was writing the comment. Also love to see you back on the RU-vid I was starting to miss your bubbly personality.

@MG2-_- 6 лет назад

About time! You finally uploaded ... Can i get a hallelujah 😂😂

@AlexDainisPhD 6 лет назад

And there are more coming soon (for real this time!!!)

@MG2-_- 6 лет назад

Btw that book " fundamentals of cartography" is indian and sometimes the high school students have a need to refer to books of the same kind because of topography work we have to do in school.

@AlexDainisPhD 6 лет назад

Oh cool! It did seem useful!

@applemauzel 4 года назад

Parafilm is also used in bartending alot just to prevent those pesky alcohol bottles from evaporating away.

@jonhowardlife 6 лет назад

Yay another Alex Dainis video!!! I shall learn something awesome today!

@kdawg2468 6 лет назад

I usually just use parafilm to cover volatile chemicals so they don't evaporate away when I store them for a while. It's cool to see the uses for it in biology.

@ElNietoPR 6 лет назад

Last video I saw from you was "DNA In Space." I went to your videos and noticed you've uploaded at least two more videos!? I had no notifications. I guess I'll use that bell thingy. Can't way too see more content from you!

@wellwithmeri8222 5 лет назад

That parafilm mixing trick blew.my.mind. Going to use that for my experiments now!

@AlexDainisPhD 5 лет назад

Right?! One of the other grad students in my lab showed it to me as a way to mix samples with loading buffer before electrophoresis and it blew my mind too! It also ended up saving me so many extra tubes that I was just wasting on mixing.

@itaroxd8214 3 года назад

Se usa también en los viveros de producción de plantas para envolver el injerto

@AfdhalAtiffTan 6 лет назад

Thank you for the video and welcome back!

@xja85mac 6 лет назад

I once used parafilm to make a spinning top out of a pipette tip and a ceramic ring from what I think was an inductor (which came from an old computer's power supply)

@pseudophd1073 6 лет назад

I somehow never made the connection between parafilm and paraffin, interesting!

@markanthonycarlovillanueva1691 4 года назад

It is good for plant grafting too.

@FilipSalomonsson 6 лет назад

And now I crave this thing I didn’t know existed five minutes ago. 😮

@hugueslefebure9107 Год назад

It has that effect. It's the funky stetchable and self sticking properties with chemical and air resistance that naturally appeals to people. Nerdy-biology people that is.

@Tjousk 6 лет назад

Small pieces of parafilm between the corners of a stack of paper with a hot air gun, and then it's a real lab staple.

@AlexDainisPhD 6 лет назад

Oh I love this idea!

@JimtheEvo 6 лет назад

You gave summer students scissors...? You're one brave grad student!

@AlexDainisPhD 6 лет назад

Not every summer student earns scissors, but these ones were special ;)

@moertelruehrer 6 лет назад

This moment, if you get a push notification about this video, currently having a box of parafilm in hand in lab... :D But I NEVER saw such a big role of parafilm :O

@AlexDainisPhD 6 лет назад

Me either!!!! I was shocked!

@supersmashsam 6 лет назад

Long time no see! I really enjoyed this video! Has anyone gone through one parafilm roll? These things seem to last forever! Judging by their retro look, my hypothesis is that parafilm rolls are self-regenerating and that only a few were made a long time ago. I demand isotopic dating! :p

@AlexDainisPhD 6 лет назад

Talking about this video with a professor in my department, she remarked on the fact that the packaging instructs "When empty, reorder from your laboratory supplier," and how silly that is, because, do they think you wouldn't do that on your own? But also, no one could ever remember having to have done so...

@xja85mac 6 лет назад

I remember that one of the analytical chemistry labs in my university was running short of parafilm, so us students were told to use it with restraint. btw, I loved this video, and so did my colleagues with which I shared it!

@AlexDainisPhD 6 лет назад

Using parafilm with restraint is a hard task! And I'm so glad you liked it :)

@kuronosan 6 лет назад

The research is strong with this one.

@luanalangloisfiorotto 6 лет назад

@manp1039 5 месяцев назад

i am curious if it is reactive to acids or alcohols(breaks down or dissolved).. or if it is non conducting of electricity

@Nicholas.Tsagkos 5 лет назад

My fav use is grafting trees! I'm searching for a cheap source of parafilm or no brand paraffin grafting tape and that's how i found out this vid! :)

@ximono 2 года назад

Did you ever find one?

@apurvasharma2370 2 года назад

is paraflm airtight? will it prevent evaporation of solvents containing alcohol or perfumes if its used to seal the bottle?

@katiecupcake101 6 лет назад

I love your videos. I am writing a novel, so your videos are so helpful!

@AlexDainisPhD 6 лет назад

@DurayStuffCrafts 2 года назад

Is this used for covered organic solvent in test tube after extraction ???? And is it also good to put tubes in freezer ???

@noorazianahsandi 3 года назад

What happen if i didnt not stretch the parafilm tape does it affect the gaseous exchange??? im using if to seal petri dish

@Anze_kotar 3 года назад

I love to graft with parafilm🌱

@randymicallef3545 2 года назад

I've searched high and low for an answer, so I'll try here. I'm trying to find out if wrapping individual batteries in Parafilm to protect them from moisture and the elements when in the field (outdoors) will work... anyone know anything about this or if there is a reason I shouldn't wrap a battery in Parafilm?

@felina_cosmicax Год назад

Do you know why a number appears on the paper that cover para film?

@RyukoChan87 5 лет назад

It is also used alot by us, chemists, and for weighting small weights :D

@bryanessig8814 5 лет назад

It is used a lot for grafting fruit trees

@quimicaextrema 6 лет назад

Hey Alex! How are you? My name is Felipe and I'm a 17yo Brazilian Education RU-vidr which was inspired a lot by your videos. In my channel I do a lot of chemistry experiments inside a homemade lab! Well, I actually want to thank you for being a motivation for me during this RU-vid years, your passion for science makes me realize that we still have brilliant minds thinking and creating. Congratulations for your work and please keep doing it, you definitely have a worldwide public and I'll help translating your videos to Portuguese if you wish so! A big shout out from Brazil! :)

@chrisneumayer4821 6 лет назад

I want to be a summer student in your lab just to be filmed opening a massive box of parafilm :D can you give us a hint about the next videos?:)

@doktorkoka 3 года назад

Is it normal that my parafilm is separated from the protective layer? When I dispense it, it's already detached.

@fymchannel3946 4 года назад

I have the same question, but in my parafilm appears 17 and 18

@ArchOfWinter 6 лет назад

I guess that's one way to get lab equipment on a tight budget.

You nerds. You love Parafilm. I understand 😍.

@aarond0623 6 лет назад

Have you thought about doing a video on the current tax overhaul? I want to go to graduate school, but tax changes are making me think I'll never get there, due to taxing tuition waivers as income.

@AlexDainisPhD 6 лет назад

I have thought about this, mostly because I've been constantly worried about it for weeks, but there's definitely an "but I'm not a tax attorney, I can't talk about that" mental roadblock in my way :(

@hugueslefebure9107 Год назад

I think i'm contacting Bemis.

I'm here for knowledge and you can offer more so I hit the subscribe button. 👍

@agravy7657 3 года назад

The most expensive saran wrap you will ever buy.

@k2l1m3n 6 лет назад

It doesn't like pathology machines. We have a machine that caps tubes with parafilm and it is ALWAYS getting jammed and needs fixing. Also it's no good for transporting specimens either.

@JoseRodriguez-yg2xg 3 года назад

Hey quick question would the parafilm used for nursery grafting be the same? I'd like to get some but the m parafilm is a bit up there lol any advice is welcome thanks!
