Dear Lab Guy, We are using an SP Bel-Art Space Saver Polycarbonate Vacuum Desiccator in the lab. I was wondering what the maximum applicable vacuum is? The manual said it hold 14 psi for 24 h but does it mean it is the max it can withstand?

Hydrometer Documentation

Dear Lab Guy, We bought a DURAC Hydrometer back in 2018 (Serial #: 4263898 ASIN: B00NG2601C Item model number: B61801-4600) on Amazon. It states everything was calibrated to the NIST but we never received a certificate. Do you know where I can find this certificate of calibration? Do you also have calibration liquids to test if the hydrometer is calibrated for purchase? Thank you!
