Parker Hannifin / Automation / Precision Fluidics Division
Series 18 Inert PTFE Manifold Valve from Parker
The Series 18 is designed for compact installation in multi-liquid systems. Available with multiple inlets and one outlet (or vice versa), the Series 18 features all wetted parts of Teflon ®. Tubing and connections between discrete valves are eliminated and dead volume is reduced. Repeatability and rapid response time make the Series 18 ideally suited for controlling mixtures of small percentages of low flow liquids. • Provides unsurpassed chemical compatibility for a wide range...

Heraeus Noblelight LLC – Optics + Analytics
Deuterium Lamps
Deuterium lamps provide an almost continuous light spectrum ranging from UV (185 to 400 nm) and discrete lines around this. This makes them the ideal light source for high-precision absorption measurement, e.g. with UV/VIS spectrophotometers and high-pressure liquid chromatography (HPLC). Our experts cooperate closely with instrument manufacturers to optimize the lamp for the particular application and the specific operating conditions in the instrument. Heraeus deuterium lamps: 1000 or 2000... (read more)
