Installing a Glass Trap in the Cold Trap
An accessory Glass Trap is available for use in the Cold Trap for use when
corrosive chemicals are used that could attack the stainless steel chamber of the
Cold Trap. Lift and rotate the two lid retainers. Disconnect the hose and remove
the Cold Trap Lid Assembly. Attach the hose from the Concentrator to the fitting
on the center tube of the Glass Trap and clamp securely. Attach the hose from the
vacuum pump or Secondary Trap to the other fitting on the Glass Trap and clamp
securely. Be certain that the drain valve is closed. Add approximately 500 ml of
ethyl alcohol to the stainless steel trap or enough to insure that the Glass Trap is at
least two-thirds immersed. Place the Glass Trap inside the stainless steel trap, lift
and rotate the two retainers to hold the Glass Trap in place.
NOTE: After a run, if the ice in the glass trap has melted, the trap must be
emptied before the cold trap is started again to prevent it from breaking.
