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 got this Baume hydrometer (Thomas Scientific art. no 6025f91 SP Bel-Art's sku B61806-0500) and I am wondering if I can use it at high temp like 70®C, I would like to use it in my chocolate making but don't want to break it.

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?
