Cold Finger Trap W/ 45/50 Joint 250 mm Made of Borosilicate

The 250mm Cold Finger Trap with 45/50 Joint is a borosilicate laboratory cooling component for compatible condensation, distillation, and vapor-trapping assemblies. Its published specifications include a 45/50 ground-glass connection and approximately 250 mm length, providing a larger cold-finger format for systems designed around that joint size.

The cooled surface provides an area where compatible vapors can condense when operating conditions are appropriate. Condensation performance depends on coolant temperature, vapor composition, vapor load, surface exposure, system pressure, and apparatus configuration. The 250mm Cold Finger Trap does not by itself guarantee solvent recovery, temperature control, or a particular collection efficiency.

Confirm that the 45/50 joint matches the receiving glassware before assembly. When used under reduced pressure, evaluate the complete system, including connected vessels, joints, seals, tubing, valves, and vacuum equipment. No specific pressure or vacuum rating should be inferred from the ground-glass connection or borosilicate construction.

Inspect the full glass body, cold-finger section, and 45/50 joint before use. Chips, cracks, deep scratches, impact damage, or damaged sealing surfaces are reasons to remove the trap from service. Avoid inappropriate thermal shock when adding cooling media and use suitable protective equipment when handling very cold materials. Support connected components to reduce mechanical stress on the glass joint.
