Hi Lab Guy, I am inquiring about the ProCulture® Cordless Homogenizer Unit for Micro-Tube Homogenizer System. Is this unit capable of lysing cells? Even smaller cell types such as sperm cells? Thanks

Dear Lab Guy, I was looking at the SP Bel-Art Reagent/Acid Pump Dispenser and found it lists the compatible bottle interfaces as GPS No. 38-430 or 38-400. I'm not familiar with these labels and I'm hoping to use it on a GL45 compatible bottle. Will this work for me?

Hi Lab Guy, I need to do infiltration of plant tissues with a solution containing bacteria. The literature suggests to expose plant tissue to a low vacuum of around 80.000 Pascal/24 inches Hg. To perform this experimental step, I am looking for a desiccator. The major difficulty I have is that those desiccators come without the vacuum gauge. I have been searching for the proper gauge and how to connect it to the tubing between the desiccator and the pump and got lost. Could you please recommend: 1) The proper and reasonably priced vacuum gauge and tubing connectors that can be used effectively with F42010-0000 or F41099-0000 desiccators, to estimate the lower pressure in a range 50.000- 101.325 pascals 2) Proper connectors and vacuum tubing

Dear Lab Guy, I tried using your Autoradiography pens on X-Ray film, but I can barely see it when I’m writing it down. Is this normal?
