Thermometer Probe Adapter 24/40 made of Borosilicate

The 24/40 Thermometer Probe Adapter is a borosilicate laboratory accessory for positioning a compatible thermometer or electronic temperature probe through glassware with a 24/40 ground-glass joint. It provides a convenient interface for temperature monitoring in compatible reaction, heating, reflux, and distillation assemblies.

Joint size and probe fit are separate compatibility considerations. The adapter's 24/40 ground joint must match the receiving glassware, while the sensing instrument must fit the probe opening and retention arrangement appropriately. Never force mismatched ground-glass connections or an oversized probe into the adapter.

A 24/40 Thermometer Probe Adapter holds or guides the sensing device but does not establish the accuracy of the measurement or guarantee a sealed system. Accuracy, response time, insertion depth, and usable temperature range depend on the thermometer or probe, calibration, apparatus configuration, and operating conditions. Follow the sensing instrument manufacturer's specifications.

Inspect the adapter before each use, paying particular attention to the ground joint and probe opening. Chips, cracks, deep scratches, impact damage, or damaged sealing surfaces are reasons to remove the component from service. Support connected glassware where necessary so the joint is not carrying excessive mechanical load, and avoid inappropriate thermal shock.

The 24/40 Thermometer Probe Adapter is useful when adding compatible temperature sensing to a standard 24/40 laboratory setup. Browse thermowells, adapters, flasks, and related components in our Borosilicate Glass Laboratory Equipment collection.
