I wanted to know how to make automatically turned off after 60 min as mentioned in the manual: ". 60 minutes after last activity: The pipette turns OFF." ?
I've just passed as a Sartorius engineer 🙌🏼 working on both Small and large Octet, Bobby @Sartorius fremont california thank you for everything 🙏🏼 I look forward to a long Career with Sartorius

We're sorry to hear you're having trouble with a stuck filter. Here's how to safely address the issue: 1. For Tacta® and Mline® Pipettes: These models feature a built-in filter ejection system designed to remove filters easily. Please refer to the specific instructions in the user manual to use this feature effectively. 2. For Proline® Plus and Picus® Pipettes, or if the Ejection System Fails on Tacta® and Mline® Models: We strongly advise against attempting to manually remove the stuck filter as this could potentially damage the cylinder and tip cone. Instead, please contact Sartorius service or an authorized service partner for professional assistance. They are equipped to safely resolve the issue without risking damage to your pipette. Your pipette's performance and longevity are our priority, and we're here to ensure you receive the best support. Thanks for reaching out!
@@SartoriusGlobal I had to give it to the lab engineer and he used an air compressor to expell the stuck prolipropilene filter. However, thank you for answering! I really appreciate it. I hope a video comes out eventually, as there is basically NO information on how to troubleshoot a stuck filter.
Why not simply use the mRNA, encoding the antigen, to produce antigen in a cell culture rather in a human body as demonstrated by the COVID19 mRNA vaccine. Traditional vaccines are derived from killed live virus, providing a multitude of antigen types, cultivated in cell cultures. Why cultivate antigens in the human body? After all, lipid wrapped mRNA nano-particles potentially invades any cell limited only by where the particles drift and ultimately destroys the invaded cell just like a virus.

Hallo, danke für die Frage und das Interesse an einer Ausbildung bei Sartorius. Die Vergütung während und nach der Ausbildung hängt vom Standort ab, in Göttingen gilt beispielsweise der Tarif der IG Metall und in Guxhagen der Tarif der IGBCE. Details zur Ausbildungsvergütung für unsere verschiedenen Standorte und alle offenen Ausbildungsstellen gibt es hier: www.sartorius.com/en/company-de/career-de/schueler-azubis
Thank you for your message. For ultrafiltration, it is not essential to use a closed feed reservoir. The retentate pressure can depend on a variety of factors, including feed flow rate, sample characteristics, and the chosen membrane MWCO. A low pressure reading should not be cause for concern provided that there is a consistent flow of permeate exiting from the cassette. If you have any further questions or would like to discuss this further, please fill in our form and one of our TFF experts will get back to you: www.sartorius.com/en/products/lab-filtration-purification/ultrafiltration-devices/tangential-crossflow?mrksrc=social&

Very good point about our tendency to not question what other scientists have done before us, and get started by imitating what they have done. Excellent presentation.
Thank you for your kind words! We're glad you found the presentation insightful. It's always our aim to encourage thoughtful discussions and fresh perspectives in the scientific community. 😊

Thank you for introducing me to this new technique. I want to know that after dispensing a reagent into a reaction mixture by reverse pipetting, if we discard the excess reagent would it be a wastage of the reagent as we also can't return it to the original sample as it can contaminate the stock? How to overcome this problem?
Dispense the aliquot from air -> less contamination risk -> able to return the excess to source vessel. Downside is that dispensing in air is more challenging, and can lead to inconsistent results if the operator is not extremely careful, also liquid properties might make this more challenging as well. Use electronic pipette which allows them to adjust the excess amount. This way they can minimize the waste.
Would you please answer this question: To have 5-10 kDa, 3-5 kDa and <3 kDa fraction of a milk protein, what vivacell ultrafiltration device should I use from Sartorius ? Thank you.
Apologies for the delayed response! While fractionation by ultrafiltration can be possible, we typically recommend that there is at least a 10-fold molecular weight (MW) difference between the substances to be separated, to achieve the most efficient separation. This is because separation by ultrafilters is primarily only achieved based on the nominal pore sizes of the membranes. With smaller MW differences, you would likely observe at least some level of cross-over between fractions, in which case using another approach such as size exclusion chromatography is more likely to provide better results.
