Hello, I am dealing with the sampling of fermentations which becomes very viscous due to micellia. We have a sampler but I suspect the tube is too thin and we are not getting a representative sample.
Any ideas to solve this sampling problem?
Thank you in advance.
Hello I already had such kind of problem .I solve the problem with the use of vacutainer which has negative pressure inside. I made a little modification in fermenter to be able to use vacutainer and solve the problem. If you can find some vacutainer without any supliment inside you can try!
Hi, Thank you for your answer Karen.
The vacutainer could get thick micelia? Because I have been looking for it in the internet and, at least the ones i've seen, present a small tube for getting sample. It is valid for other fermentations but I am not sure if being so thin It could helpp get a representative sample.
Thank you in advanced!

Hello you can make your own big vacutiner just use some safe and appropriate glass reservoir and rubber cap, than pump down air by needle and you will get negative pressure inside and find the way how to use it).
