Rheodyne® Model 7125 Injector

The Rheodyne Model 7125 syringe loading injector allows injection of the entire contents of the syringe into the sample loop – no need to flush the valve between injections except for trace analyses. It also injects samples from a partially filled loop saving time by eliminating the need to change the sample loop.
The Model 7125 injector can be used at pressures up to 7000 psi (490 kg/cm2) and is supplied with a VESPEL® rotor seal for operation at pH 0-10 (use a Tefzel® seal at pH 0-14). A 20 μL sample loop is included; order additional loops separately.
When selecting replacement seals, use VESPEL seals to pH 10; Tefzel seals to pH 14.
