Description
A matched pair of degassing chamber assemblies that passed two separate tests each: flow paths verified clean, and the assembly verified to hold vacuum after removal. Most parts sellers can offer neither.
Bench report
- Functional
- Two tests, both passed, on each assembly. First, the flow paths were verified clean by capped-inlet isolation. Second, each assembly was verified to hold vacuum under a capped-port decay test after removal, with the flow paths left open - which also confirms the internal permeable tube is intact, because a cracked coil would vent the chamber straight out through the open flow path. That second test is what earns the word vacuum-tested here.
- Cosmetic
- Exterior condition only, which is all anyone can assess without opening them. Both housings are clean and undamaged - no cracks, no distortion, no damage to the barbed ports, fasteners all intact and the pair still bolted together as it came out. Barcode serial labels are crisp and fully legible in the photographs.
- Tested
- Flow paths verified clean by capped-inlet isolation - assembly MDB 25717. · Flow paths verified clean by capped-inlet isolation - assembly MDB 25716. · Assembly verified to hold vacuum under a capped-port decay test AFTER removal, with the flow paths left open - MDB 25717. · Assembly verified to hold vacuum under a capped-port decay test AFTER removal, with the flow paths left open - MDB 25716. · Because that test was run with the flow paths open, a cracked internal coil would have vented the chamber. Holding vacuum therefore also confirms the internal permeable tube is intact. · Both serial labels read and photographed: MDB 25717 and MDB 25716.
- Not tested
- Degassing performance / gas-transfer efficiency - NOT measured, on this or any module in this batch. · The housings have NOT been opened. The internal coils have never been seen, and nothing is claimed about the condition of the chamber interiors. · No flow rate, back-pressure or solvent-compatibility testing. · Not run in a receiving instrument after removal. · No residue analysis. Prior solvent history is unknown.
