Why choose a Hamilton laboratory electrode? Hamilton electrodes are precision instruments known for high quality, long lifetime and remarkable performance in a wide range of applications. The sensors are designed to help you with the daily work in GLP environments. Due to the indelible serial number on the sensor and a certificate with serial number and the measured millivolt values for your documentation, traceability is guaranteed. Hamilton can also supply the most accurate laboratory electrode in the market. Our Single Pore Glass was tested by PTB (Physikalisch-Technische Bundesanstalt, Germany)...

Laboratory Electrodes-3

The Single Pore® concept Precise, reliable and rapid readings with a patented liquid junction ensuring optimal contact between electrolyte and sample Since its introduction in 1991, the Single Pore concept continues to prove its reliability. Instead of the many tiny pores in a ceramic diaphragm, a Single Pore about 200 times larger in cross-section (in the form of a capillary) ensures reliable contact to the sample. This Single Pore is practically impossible to clog. In combination with a dedicated electrolyte, the flow rate through the pore is defined, resulting in enhanced contact between the...
