 Featured Question and Discussions

Plenty of discussions are happening on LabWrench all the time. We have many questions come in daily from users that are seeking advice from fellow users and lab professionals. Can you help any of these users find the answers they are looking for?

Is a Leica DMIRB suitable for teaching petrographic polarizing microscopy?
We have acquired a secondhand Leica DMIRB Type 090-132.102 inverted microscope. Has any one used one of these for petrographic polarized light microscopy? We don't need to do anything fancy, we are an educational institution for high school students. We just need to show the changes in the view of thin sections as the polarized filter is rotated. Genuine petrographic microscopes have non-polarizing optical elements. How well does this instrument compare?

Tali calibration protocol
We are having a problem with our Tali. In a simple methodology for counting dead cells, we are having a big difference betwen traditional trypan counting and Tali Green Dead Cells kit. Are there some calibration hint that we can perform?

CO2 Detection Problem
We recently purchased this CO2 incubator, model 3074. A problem that I faced yesterday is that the incubator suddenly started displaying the level of CO2 as -5% with a low CO2 alarm. Thinking that may be its time to replace the CO2 cylinder, I checked the cylinder for the amount of gas remaining in the cylinder. It was approx. 80% full. Also, it was back to normal CO2 level, i.e. 5% after 3-4 hours. Again when I opened the door of the incubator, the level went down to -5%, which again got normal after 3-4 hours. I am not able to figure out what the problem is. Is it something related to the CO2 sensor or what? Please help me out with the best possible solution.
