Cold Finger Trap W/ 24/40 Joint Made of Borosilicate

The Cold Finger Trap with 24/40 Joint is a borosilicate laboratory component for compatible condensation, reflux, distillation, and vapor-trapping assemblies. Its 24/40 ground-glass connection allows it to integrate with matching laboratory glassware using the same taper standard.

A cold finger provides a cooled surface on which compatible vapors can condense. Actual trapping performance depends on coolant temperature, vapor composition, vapor load, apparatus geometry, operating pressure, and procedure. The Cold Finger Trap with 24/40 Joint should therefore be selected as one part of the complete system rather than as a guarantee of recovery or condensation efficiency.

Verify the 24/40 connection before assembly and support attached glassware appropriately. If the trap is used in a reduced-pressure setup, inspect and evaluate all connected joints, tubing, seals, valves, vessels, and vacuum equipment. A ground-glass connection does not establish a specific vacuum, pressure, or leak rating.

Before every use, inspect the glass body, cold-finger section, and ground joint for chips, cracks, deep scratches, impact damage, or defects. Avoid inappropriate thermal shock when introducing or removing cooling media. Very cold materials can create additional handling hazards, so use suitable personal protective equipment and procedures for the coolant involved.
