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?

Dear Lab Guy, Can you advise if there are any special handling requirements for disposing of water treated with the Bel-Art Aqua-Clear?

Dear Lab Guy, Vibrations from our process equipment are being transmitted through a lab bench with an IR spectrophotometer. Vibrations were measured at 33 Hz both in horizontal and vertical orientation. Amplitude are 15.4 micron in the vertical and 30.5 microns in the horizontal direction. The spectrophotometer weighs 10 lbs. (4.5 Kg). Would the Vibrasorb Premium mount work for this application? Paul W
