Hello all, I am strongly considering buying a vacuum pump and attempting to assemble a practical lyophiliser for use in preserving bacterial stocks and in producing small samples of protein or the like. I'd like to know if anyone on the list knows of a prior attempt to do this?
My thinking is that through use of a vacuum-resistant container (perhaps a sturdy bell jar?), metal piping to convey the vacuum, and a coil of said piping immersed in dry ice or cooled through a thermoelectric cooler system, you could mimic the principal parts of a commercial system. Those being: Hard vacuum, clear chamber to admit gentle heat by irradiation, condenser to freeze vapour out of the vacuum line before hitting the motor. Any feedback very much appreciated; commercial systems, even the smallest, cost several thousands, whereas a hard vacuum pump can cost as little as €100. Thanks!
