[Biofilms] compression test on biofilm

Dear all,


I am a mechanical engineer who is measuring biofilm mechanical properties. I
am currently doing compression tests on mixed biofilm. I have two questions:


1.	Biofilm used in the test is a few weeks old, do I expect to see big
difference in results when I do it on very fresh biofilm?
2.	I had a 100N load cell and I know sensitivity is low, does it affect
results in unacceptable way?
3.	Biofilm is placed in a glass container and I have a surface tension
problem and biofilm sticks to the glass wall, any recommendation to reduce
adhesion? I used PTFE lubricant but didn't work well.


Thanks in advance,
