Dear Lab Guy,
I am looking for a pipettor that can be adjusted to dispense liquids in .5ml increments. I purchased one of the Roxy M pipettors recently but I am not sure if this is really what I am looking for? - Ben F.

Dear Lab Guy,
I have been trying to homogenize heart tissue in the Bel-Art Mini Liquid Nitrogen Cooled Mini-Mortar set (H37260-0100)
The pestle did not reach the bottom of the tube and the tissue got stuck at the bottom, so I did not achieve the desired result. I used regular 1.5ml Eppendorf tubes. Could you please advise me on what can be done about it? Thanks. - Olga M.

Hi Lab Guy,
Our customer needs to seal in a desiccator, slides with samples that needs to be transported.
We would like to know the best way to do this and if you have a small desiccator with a sort of "rack" for slides. Thank you for your help. - Anna C.

Dear Lab Guy,
I am trying to set up a recirculating system for an acid bath for etching zinc plates for a traditional printmaking process. We are using approximately 4.5 gallons of water and 0.5 gallons of concentrated nitric acid, so it seemed like your hand pump H32787-0000 and 5-gallon carboy F10795-0000 might be a good starting point. Approximately what volume is delivered per stroke at a low head like a foot or two? Alternatively, how many strokes to empty? Also, would it be acceptable to leave the pump in the acid indefinitely? Thank you for your assistance. - Walt P.
