• • Proprietary pH sensor technology and premium materials from Switzerland
  • Low-resistance LabSen® micro cylindrical glass membrane, suitable for micro-volume pH measurement (>30 microliters)
  • The stainless steel protective shaft ensures the durability of the slim glass tube
  • Long-Life Reference System, improving the stability of the reference and extends the electrode's service life
  • With the micro container (sold separately), it can test as low as 15 microliters.

Backed by proprietary Swiss sensor technology and premium materials, LabSen 241-3 Glass Micro pH Electrode is designed for micro-volume samples (≥30 microliters), especially suitable for microplates, microcentrifuge, and microbiological samples. With the ultra-micro container (sold separately), it can test as low as 15 microliters.

Unique Glass Membrane - LabSen 241-3 pH electrode adopts a micro cylindrical sensor tip (top end ø3mm, stainless steel ø4mm), making micro-sample pH testing easier than ever, and can be tested in high-temperature samples (up to 212°F). The stainless steel protective shaft ø4mm) ensures the durability of the slim glass tube.

Long-Life Reference System - composed of a glass tube, AgCl, and a reference silver wire. The top end of the slim glass tube is stuffed with cotton, which prevents the reaction between AgCl and electrolyte when the temperature changes. It improves the stability of the reference system and extends the electrode's service life.

The electrode uses a BNC connector, compatible with any pH meters that use BNC connectors. No temperature sensor is built-in. Users need to have a separate temperature probe (ex: Apera Instruments MP500) to enable ATC or manually input temperature to achieve temperature compensation.
