stickness means not dry...
depending on material you dry.
Some materials, who are completely dry even get static charge.. therefore, almost impossible to weigh...(we use ion pistols to de-static our samples)
That way the sample must've melted, forming liquid phase, considering the room temperature and the length of the vacuum process, which is undesirable for sublimation. They have to be kept frozen during vacuum.
nice vedio explaining the process
But how is heat transferred in negative pressure? I thought there would be some heat exchange tubes around the samples?
I am going to have to buy this for production of butane extracted hashish, I have been manually doing this method for years now, and I am sick of using Ball jars and food savers to achieve my vacuum, though, it does work well.
thank you for the information...I just bought a Food Saver!
Aha epic
Sir Why use parafilms only ?
Thanks for giving the great video,I think it offerd me a lot of inspiration for my writing paper,and I'm already subscribed this channel,and best wishes to the channel.
Falaaaaaaaaa ❤❤❤❤❤
when cap is removed , there is a lot of chance for the sample to become contaminated due to air borne particles. how can we avoid this risk?
having a clean room with laminar flow hepa filters
With a rubber cap and a small punctured hole that will normally keep the rubber together and the hole closed but will open under negative pressure to let the vapor out?
Excellent video, and excellent music as well! Where have you found the music?

Nice
how do you avoid contamination when you lyophilizing bacterial cultures?
@Alt F4 but they can all revive when you put them in a suitable media (borth/agar) ?

Danas mi je rođendan. Moze jedan lajk?😁
How about the pump? when do on turn it on and off?
Kad ti paše
OK BOOMER
what a nonsmart design!
Great video! Voice over (by a human) could have made it better.
