Needle tip

Hypodermic needle thermocouples (17 gauge) are ideal for measuring and controlling the temperature of small volumes and inert reactions. The temperature measuring end of the thermocouple is at the tip, so only the first 2 mm of the probe requires liquid contact for accurate temperature measurement. Forms an air tight seal when inserted through a septum. Stainless steel needles are sealed on the end for liquid tight applications. Available in 3.5” and 7” lengths and with or without Teflon coating. Each comes with 72 inches of attached Teflon extension wire.
