    Hi! Great videos! Could you write the reference number of your couvette? I use a foldable couvette 0,1mm but I have problems with evaporation and bubbles, especially when the probe is heated. Also do you have any tips for different results of the same sample? Sometimes I put on the same protein (from the same eppendorf), the same amount and I think that the results are different. Maybe its because the couvette that enhances evaporation? Thanks :D

    Can you use this one protein samples which contains lots of protein? Or only for a single purified protein? Like for example I’m using a serum sample after depleting albumin and igGs. After performing Western blot I found that the bands were much larger than target protein size. I also tested it with different antibodies but the results were always much larger (almost double). So I thought I may need to take another look at concentration measurements cause perhaps the sample is too concentrated so here I am.

Does it means the further spectra obtained from samples will be already subtracted from buffer? Do i still need to click on baseline to manually adjust it after smoothing? If so, how i do the adjusting?

      That is part of the rehydration step. I don't recommend skipping it. You can see a clear difference in how the lipid looks. In the first lyophilization step it looks very dense but after the second, it will look very fluffy and you know that it's been rehydrated.
