Cheminert Injectors for
Nanovolume® HPLC and UHPLC
pages 146, 152–155
New nanovolume® injectors feature a uniform flowpath as small as 100 microns,
with specially designed fittings for 1/32" or 360 micron PEEK, fused silica, or Valco
electroformed nickel tubing. Models are rated from 5,000 to 20,000 psi, with
most having a proprietary coated stainless stator and high-strength PAEK rotor
to ensure long periods of maintenance-free operation.
Cheminert Injectors and Valves for
HPLC and UHPLC
pages 147, 156–163
The Cheminert line includes 4, 6, 8, and 10 port versions. The submicroliter
injector has an injection volume as small as 10 nanoliters. Valves feature 1/16"
zero dead volume fittings, with bore sizes from 0.15 mm (.006") to 0.75 mm
(.030"). Most models are available in manual, air, or electrically actuated versions,
and some can be ordered with a proprietary coated stainless stator and high-
strength PAEK rotor to ensure long periods of maintenance-free operation.
Cheminert Injectors and Valves for
Low Pressure Applications
pages 148, 164–167
Cheminert’s two position design offers 4, 6, 8, or 10 port configurations. The
design features a choice of Valco 1/16" zero dead volume fittings or 1/4‑28
Cheminert internal fittings for 1/16" or 1/8" OD tubing. All models are available
in manual, air, or electrically actuated versions.
Cheminert Selectors
pages 150-151, 170–177
Choose among 4, 6, 8, 10, 14, 20, 24, or 26 position stream selection valves, in high
pressure and low pressure models. A variety of configurations are available with
bore sizes from 0.10 mm (.004") for HPLC column selection to 4.6 mm (.180") for
applications requiring minimal restriction across the valve. Metal or all-polymeric
valves can be ordered, with models available in manual, pneumatic, or electrically
actuated versions.
40,000 psi Ultra-High Pressure Injector System
page 84
The VICI 40K injector is comprised of six miniature air actuated needle valves,
plumbed to simulate the flow path of a conventional rotor/stator injector.
An integral controller sends the on/off positioning signals to each valve,
coordinating them to perform load, inject, and flush functions.
