Does anyone have a pressure cooker they can donate to sudo room? We need one for the following projects: * open bio lab :For general sterilization of tubes, pipette tips, glassware, etc. * sudoshroom - mushroom growing :For sterilizing growth medium * subiir - the sudo beer :For sterilizing glycerol for glycerol stock of beer yeast. Means we don't have to buy yeast every time. -- Marc Juul
