columns for 3 zeros? lol
maybe if you don't know where to look. you can sometimes can find capillary columns for 70 or less.
check with liquidators/surplus. don't necessarily need an interface unless you're going to connect it to a computer. one can use a chart recorder, or an integrator. I'm actually selling a Linear 1100 chart recorder for 20 bucks.
although NI interfaces are nice...recently picked up a USB-6009... analog/digital I/O; interfaced to LabView, one can be used for both signal acquisition and event control/automation. LabView is great if you don't have the OEM control software for a machine.

GC/LC specs basically measure potential, so their output is typically mV.

Last chiral HPLC column we bought was a little under a grand

you guys don't pack your own?
granted, the 100 um Acquity column we recently got was $557

but I just use capillary (CE-MS), 18-crown-6 to separate chiral compounds. much cheaper.

I remember back in the old days at the hive someone found a Parr hydrogenation apparatus in the local uni dump. It appeared o be in good condition.

I would be extra careful with that one, but still it is amazing what you can find there.
It is perhaps the narcotic. Hyoscine affects certain people very oddly. One cannot be sure. Sometimes, these cases take strange forms. The victim becomes in a sense, 'mediumistic', a vehicle for all the intangible forces in operation around her.

A friend just scored several functioning heating mantles and two heated stirplates at his university... but those asses cut all the cables off before they throw them away so nobody could use them readily ;D

Maybe they had an inspection.

My instructor in chem lab told us to not spill powder on the heating mantles or else parts of the net will burn and on inspection day, the inspectors are just cutting off the cables so they can´t be used anymore.
Obviously they are still safe to use, but guidelines seem to be stupidly strict  :D
