Abstract
An improved cold trap of the type having a cooling mechanism (e.g., one or more cold fingers and optionally a cooling coil), to accept a gas stream to condense out volatile vapors, and a seal that contains the gas stream within the cold trap. The cold trap accordingly exhibits a flow impedance and a condensation efficiency. The improvement includes a baffle and the seal made rotatable, to rotatably hold the baffle and the cooling mechanism within the cold trap thereby allowing adjustment of the flow impedance and the condensation efficiency of the cold trap.
Claims11
An improved cold trap of the type having:
- a flow impedance and a condensation efficiency;
- and
- a cold finger to accept a gas stream to condense out volatile vapors;
- and
- a seal to contain the gas stream within the cold trap;
- the improvement comprising:
- a baffle;
- and
- the seal rotatably holds said baffle and the cold finger within the cold trap thereby allowing adjustment of the flow impedance and the condensation efficiency of the cold trap.
An improved cold trap of the type having:
- a flow impedance and a condensation efficiency;
- multiple cold fingers to accept a gas stream to condense out volatile vapors;
- and
- a seal to contain the gas stream within the cold trap;
- the improvement comprising:
- at least one baffle added between at least two of the multiple cold fingers;
- and
- the seal rotatably holds said at least one baffle and the multiple cold fingers within the cold trap thereby allowing adjustment of the flow impedance and the condensation efficiency of the cold trap.
