Visible & UV/Vis Spectrophotometers

Visible & UV/Vis Spectrophotometers Accurate Precise Affordable

S20 Series UV/Vis Spectrophotometers The Unico S20 Series Spectrophotometers are simple, flexible, easytouse and maximize value while providing performance you would expect for a 5nm bandpass instrument. The S20 Series simplicity is reflected in its attractive price without sacrificing accuracy and precision. The value is evident from the performance provided every day, all year. The flat, lowprofile design minimizes bench dead space, allowing room for cuvette racks, notebooks or a laptop computer. To simplify documentation, the S20 Series spectrophotometers can be controlled from UNICO Application Software for Windows through the builtin RS232C port. The standard software package expands the applications to include standard curve, Kinetics (Abs. vs Time) and the advanced software package further adds DNA/Protein analysis and Scanning capabilities. Test data can be exported into Microsoft Excel for further analysis. EasytoUse, EasytoRead Display The twoline, LED display is large enough to read from any angle and distance, so there is no need to search or squint. For UV models (S20UV and S20SUV), a simple push of the button on the display panel allows you to turn on/off either lamp, extending the lifetime. Readily switch modes from Absorbance to % Transmittance, or enter a Concentration or Dilution Factor. No complicated menu to slow down technicians from completing other important tasks. The standard large, flexible sample compartment has a smooth 4cell holder with 4 glass cuvettes and 2 quartz cuvettes (for UV models only) included. A wide variety of accessories are available. Four models to choose from: S20 Visible Spectrophotometer S20S Visible Scanning Spectrophotometer S20UV UV/Vis Spectrophotometer S20SUV UV/Vis Scanning Spectrophotometer Specifications Model Wavelength Range Bandwidth Optical System Wavelength Accuracy Wavelength Repeatability Wavelength Readability Photometric Range Photometric Accuracy Stray Light Stability Standard Cell Holder Sample Compartment Display Output Software Light Source Power Requirements Instrument Dimensions Instrument Weight S20 & S20S (Visible) S20UV & S20SUV (UV/Vis) 325nm 00nm 200nm 00nm 5nm 5nm Single beam, grating system 200 lines/mm Single beam, grating system 200 lines/mm ±nm ±nm nm nm 025%T, 0.2.5A, 0999 C (0999F) 025%T, 0.2.5A, 999C (0999F) ±0.004A @0.5A ±0.004A @0.5A <0.3%T @ 340nm & 400nm <0.3%T @220nm & 340nm ±0.002A/hr @500nm ±0.002A/hr @500nm 4position mm cell changer 4position mm cell changer Accommodates 0mm pathlength cuvette with optional holder Twoline, 9digits Twoline, 9digits RS232C RS232C Optional (S20), Standard (S20S) Optional (S20UV), Standard (S20SUV) Tungsten Halogen Lamp Tungsten Halogen/Deuterium Lamp 5V/230V switchable 5V/230V switchable 470mm(W) x 400mm(D) x 40mm(H) 470mm(W) x 400mm(D) x 40mm(H) 8.5 (W) x 5.7 (D) x 5.5 (H) 8.5 (W) x 5.7 (D) x 5.5 (H) 2kg (26 lbs) 4.5kg (32 lbs) Simple Solutions for your Spectrophotometry Needs ~ ~
