Carry-over Contamination Free Reference Electrodes
Weiss Contamination-Free, Double-Junction Reference Electrodes are designed for working with Ion-selective electrodes. The Contamination-Free, Double-Junction Reference Electrodes come with two versions; epoxy body with Teflon ceramic tips for a general purpose, and glass body with Teflon ceramic tips for samples with organic solvents. Both electrodes have the changeable or replaceable ceramic wick junction. With a changeable or replaceable junction, the electrode can completely eliminate the "carry over" contamination and junction clog problems of a traditional reference electrode. For instance, a reference electrode with a ceramic wick saturated with KCl, is not applicable to the measurement of chloride and potassium ions since it will interfere with the measurement by releasing KCl from the ceramic wick into the sample. With Contamination-Free reference electrodes, the ceramic wick junction can easily be changed to, for example, a chloride-free ceramic tip. Another advantage is that when the reference junction was clogged by the dirty sample or other materials, no problem at all, just simply replace it with a new ceramic junction. These Contamination-Free reference electrodes can be used for any combination with ion-selective electrodes including pH without contaminating sample solutions. It is also very economical because one reference electrode can work for many different ion measurements. Both epoxy-body and glass-body Carry-over Contamination Free reference electrodes come with 2 Teflon ceramic tips.
Glass Body Double and Single Junction Electrodes Weiss Glass body Double-Junction Reference Electrodes are designed for working with Ion-selective, pH, ORP electrodes, and potentiostats. Side-arm electrodes are the ideal for titration.
Really-Flow™ Reference Electrodes
Weiss Really-Flow™ reference electrodes have a free flowing junction, provide optimal flow rate (adjustable), resulting in better reproducibility. The junction design permits easy cleaning, which improves performance and extends electrodes life. These long-lasting electrodes have no ceramic or fiber junction to clog. Viscous and dirty samples are no problems for the electrodes. Just press down on the cap to open the sleeve and flush, renew the junction; release the cap and you are ready to take more measurements. These reference electrodes are constructed by rugged & high chemical resistance epoxy body and with refillable Ag/AgCl reference cell with double or single junction.
