Teamed with TECHNOLOGY

Briefs

Accurate analysis of complex materials is a routine matter, thanks in large part to leak-tight containment and repeatable control of carrier gases and solvents ir the chromatograph.

Since 1955, these valves and fittings have been teamed with the technology of analytical chemistry for the benefit of all industry.

Reliability • assures system integrity over

the full range of pressures and temperatures

• provides precise repeatability

• reduces costs Leak-Free Sealing • provides consistency in

liquid or gas systems • insures performance at high

or low pressures and in heated systems

• protects samples from contamination

• minimizes maintenance, repair, or service of the instrument

• simplifies column changes and reduces downtime

Optimum Size, Capability, and Selection • minimize space

requirements • facilitate instrument mainte

nance and service • insure functional

performance Local Response to User Needs • local stocks for immediate

delivery • local representatives for

technical support • local service backed up by...
