Variable Wavelength Detector

Priced below any other variable wavelength detector and including the analytical flowcell, the DVW-10 is a high quality UV-Vis variable wavelength detector capable of 195 to 800nm operation. It offers the best price/performance ratio around. Why buy performance specifications you do not need and at budget busting prices that make no sense?

The DVW-10 interfaces with anybody's HPLC system. Replace your aging UV-Vis detector now at a cost probably less than you paid for it originally.

FEATURES
  • Small, lightweight variable wavelength detector with scrolling controls and absorbance and wavelength values on the front.
  • Complete UV-VIS operation from 195nm to 800nm
  • Double beam optics (Reference and Sample Paths)
  • All wettable components are constructed of PEEK, Teflon, Tefzel and quartz, making the detector compatible with biochemical systems; stainless steel is an option with no difference in price.
  • Flowcells are also available for prep and microbore in PEEK contruction.
  • Eight absorbance ranges via scrolling up and down controls.
  • Sensitivity levels available for over 95% of all applications.
  • Digital read-out of absorbance and wavelength.
  • Analog outputs for absorbance and wavelength available at back of instrument.
  • Absorbance and wavelength remote control available via rear connector contact closures.
  • Scrolling selection of wavelength.
  • An analytical flowcell is standard and included in the instrument price. Stainless steel option is also available.

The DVW-10 is simple to operate, has a small footprint, is light weight and is thus ideal for those situations where bench space is a premium. Selection of absorbance ranges and wavelength is accomplished via scrolling keys on the front panel or remote selection via voltage contact closures available at the cable output at the rear of the instrument. Autozero wavelength selection and event mark controls are also on the front panel of the instrument. Autozero can also be controlled remotely. Absorbance and wavelength are available on a 4.5 digit display.

The DVW-10 uses a deuterium lamp for 195-360nm operation. Wavelengths from 360 to 800nm are achieved with an optional pre-aligned tungsten lamp assembly.

Its unique modular design, including an innovative optical bench, permits easy configuration of the instrument for OEM applications. The available flowcells for the DVW-10 (also may be used for the DLC-20 and DDW-10) are an analytical flowcell (SS and PEEK) microbore (SS and PEEK), prep, and semi-prep; the latter two are of PEEK construction or SS. A capillary cell is in development.
