Micro Valves for LC and GC NEW
Simplify your liquid or gas handling application with a VICI Precision Sampling
Micro valve. The unique design of the fitting detail allows a leak-free seal with
no potential for rotor damage from overtightening. Wetted parts are PEEK and PTFE.
Product information

M Series liquid handling pump
The Cheminert M Series is a new generation pump for precision handling of liquids
and/or gases, producing a bidirectional flow with a range to
six orders of magnitude. An excellent replacement for
syringe pumps, it offers better performance and eliminates the need for
refill cycles and syringe changes.
Product information

Hollow plunger syringe
This syringe features an integrated 3-way valve on its hollow plunger and an on/off valve at the front end,
opening a whole new world of applications.
Product information

Syringes for diluter/dispensers and automated instrumentation
With a 6/32 UNC female thread in the plunger head, this syringes is designed to work with the
most common diluter/dispenser and automated robotic instrumentation.
Product information

M Series Diluter/Dispenser Currently in development
The Cheminert M Series Diluter/Dispensers simplify the sample preparation process for
dispensing and diluting liquids. The user-friendly Wizard format eliminates all the math
calculations and external charts associated with diluting and dispensing applications.

Cheminert liquid handling injectors and valves
High pressure models are designed for 1/32" or 1/16" OD tubing, in a variety of bore
sizes and pressure ratings. Low pressure versions are available for 1/16", 1/8", or, for maximum flow,
1/4" OD tubing.
Most are available in 4, 6, 8, and 10 port configurations.

High pressure
Low pressure
Multiposition stream selectors

Valco C6W liquid injectors
Rated at 5000 psi/75°C, the 6 port Valco C6W injector has proven to be a robust, reliable HPLC
system component. Connections are made with industry-standard Valco zero dead volume fittings,
and the liquid contact parts are available in a wide variety of optional materials to meet any
application requirement.
Product information

On/off and prime/purge valves
In prime/purge valves, mobile phase flows around the needle when the valve is
closed, relieving the back pressure from the column. When the valve opens,
mobile phase vents to waste to prime the pump. The on/off function is
self-explanatory.
Product information

Fittings and accessories for liquid handling
Cheminert fittings are ideally suited for applications requiring an inert, biocompatible,
metal-free flowpath. Wetted materials are PFA, FEP, CTFE, or PEEK, and uniform flow passages
minimize mixing. The wide selection of adapters allows connection to male and female luers, 1/16",
1/8", and 1/4" metal and plastic tubing, 1/8" and 1/4" pipe thread, and glass tubing.
Product information

Syringes
The VICI Precision Sampling line of syringes includes basic sample injection
models in a variety of sizes and needle styles, syringes customized for various
injectors on the market, and several other unique models.
