Glass Thermometer Joint Adapter 24/40 Made of Borosilicate

The 24/40 Glass Thermometer Joint Adapter is a borosilicate laboratory accessory for incorporating a compatible thermometer or temperature probe into glass apparatus using a 24/40 ground-glass connection. It provides a dedicated interface for positioning a sensing instrument in reaction, heating, reflux, or distillation setups.

The 24/40 taper should be matched with receiving glassware using the same joint standard. Probe or thermometer diameter is a separate compatibility consideration and should be checked before assembly. Never force the adapter into an incompatible ground joint or force an oversized sensing instrument through the probe opening.

A 24/40 Glass Thermometer Joint Adapter positions the sensing device but does not determine temperature accuracy. Measurement accuracy, response time, usable range, and appropriate insertion depth depend on the thermometer or probe, its calibration, apparatus geometry, and operating conditions. Follow the sensing instrument manufacturer's specifications.

Inspect the adapter body, ground joint, and probe opening for chips, cracks, deep scratches, impact damage, or other defects before use. Support the surrounding apparatus appropriately so the adapter is not exposed to unnecessary side load. Borosilicate construction provides useful thermal characteristics, but the glass should still be protected from inappropriate thermal shock.

The 24/40 Glass Thermometer Joint Adapter offers a straightforward way to add compatible temperature monitoring to standard-taper laboratory glassware. Browse thermowells, probe adapters, flasks, and related components in our Borosilicate Glass Laboratory Equipment collection.

Frequently Asked Questions

What joint does the adapter use?
The adapter has a 24/40 ground-glass connection. Match the receiving joint's size and orientation.

Will any thermometer fit?
Probe diameter and insertion depth are separate requirements. Check the opening and sensing instrument specifications before assembly.

Does the adapter improve measurement accuracy?
It positions the instrument. Accuracy depends on the instrument, calibration, insertion depth, apparatus, and operating conditions.
