Product Category Description:

Produce 18.2 megohm-cm water quietly while maintaining a small laboratory footprint. A 0.2µm absolute final filter assures water is bacteria- and particle-free. Volumetric dispensing eliminates overflow accidents when filling carboys. Standby mode maintains water purity during periods of non-use, and an automatic sanitization cycle keeps the system clean.

The RS-232 output permits documentation of water purity. Remote, multi-language display allows monitoring of output resistivity, conductivity, and temperature up to 3m (10') from the system. Features automatic calibration verification and NIST module for in-field calibration.

Systems can be wall- or bench-mounted. Systems are supplied with brackets for wall mounting. A pressure regulating valve adjusts to feedwater pressure fluctuations. Unique “one-connection” cartridge packs are easy to replace. Available in four application-specific models:

The DIamond Analytical model is ideal for ion chromatography, atomic absorption, and other sensitive analytical procedures.

The DIamond UV model features a dual wavelength UV lamp to produce water with less than one ppb total organic carbon. Perfect for laboratories performing HPLC, gas chromatography/mass spectrometry, and TOC determinations.

The DIamond UF model incorporates an ultrafilter to produce water with less than 0.005EU/mL and log reduction values over 6. Automatically flushes water to drain, preventing contaminant build-up on the membrane. For laboratories requiring pyrogen-free water.

The DIamond Life Science model integrates a dual wavelength UV lamp and ultrafilter. Output has less than 0.005EU/mL, less than 3ppb total organic carbon, and no detectable DNase, RNase, and DNA. Ideal for laboratories performing PCR†, electrophoresis, and cell and tissue culture.

For further customization, four different cartridge packs are available (sold separately).
