AI3161 LabSen 241-180 Glass-body pH Electrode for NMR Tubes (3mm diameter, 180mm length) by Apera

Built with proprietary sensor technology and premium materials from Switzerland, Apera LabSen 241-180 Glass Micro pH Electrode is designed for micro-volume samples in slim containers such as NMR tubes (minimum sample volume: 50 microliters).

LabSen Glass Membrane - LabSen 241-180 pH electrode adopts an ultra-long 180mm micro cylindrical glass membrane (ø3mm), making NMR tube pH measurement easier than ever. And it can be tested at high-temperature up to 212°F. The low-resistance membrane (<450MΩ) helps you quickly get a fully stabilized reading.

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 standard 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.

08491-03 Gen-Purp Fle x Thermistor, Vinyl Sheath and Tip, Phono Plug, 100ft Lead by Digi-Sense

Time constant is the time required to reach 63.2% of the new reading. To determine how long it will take to reach 99% of the new reading multiply the time constant by five.

Note: The temperature range is for the probe tip only. The handle material may be affected if the probe is rated higher than the handle depending on exposure time, application, and handle material. ABS handles are rated to 220°F (104°C); PVC handles are rated to 200°F (93°C); Stainless Steel handles are rated at 450°F (232°C); Mini Connectors are rated to 392°F (200°C).

• Probes are electronically isolated and come with a 10ft lead with a ¼" phono plug (unless otherwise specified).
• Probes are designed for multiple applications.
• Epoxy coated probes can be used in liquid immersions.
