LabSen 821 Refillable Glass-body pH Electrode for Biotechnology, Pharmaceuticals, Protein-containg Liquids, BNC Connector

• Proprietary pH sensor technology and premium materials from Switzerland
• Protelyte electrolyte is designed for samples in the applications of biotechnology, pharmaceuticals, and protein-containing liquids
• Built with LabSen S-type hemispherical glass membrane, featuring fast response and high firmness
• The blue gel inner electrolyte eliminates the chance of any air bubbles inside glass membrane
• Lead-free glass body

Backed by proprietary sensor technologies and premium materials from Switzerland, Apera LabSen 821 pH Electrode is designed for accurate and precise pH measurement of samples in the applications of biotechnology, pharmaceuticals, food, and beverage.

Silver Ion Trap Reference System – On top of the Long-Life reference system, a silver ion trap is added to minimize junction clogs caused by proteins and sulfites, significantly extending the service life of the electrode in protein solutions testing.

Protelyte – a tasteless, odorless, and microorganism-safe electrolyte that fully complies with EC Regulation 1935/2004 for safe contact with food products. This makes it an optimal choice for accurate measurements in biotechnology applications, including biological fluids, enzyme solutions, and protein-containing solutions, TRIS buffers, etc. as well as in food and beverage applications e.g. milk, yogurt, jam, sauce, etc.

LabSen S-type hemispherical glass membrane - low resistance and high firmness, rendering fully stabilized readings in 15 to 30 seconds, and is yet 10 times stronger than traditional glass membranes, highly resistant to general impact, eliminating the chance of accidental breakage.

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.
