Scanning spectrophotometers from Jenway for measurements in the visible and UV range.Model 7200 (VIS): wavelength range of 335 to 800 nm with a spectral bandwidth of 7 nm.Model 7205 (UV-VIS): wavelength range of 198 to 800 nm with a spectral bandwidth of 5 nm.Both spectrophotometers are ideal for a variety of applications in education and routine testing in clinical, veterinary, pharmaceutical and QC laboratories.The 72 series spectrophotometers offer measurement modes for single wavelength with basic absorbance and % transmittance; concentration determination (via reference standards or calibration curves with up to 6 standards), full spectrum scanning and kinetics for up to 3 simultaneous wavelength measurements.The colour touchscreen user interface provides fast and easy set up and navigation of the instrument. The 4" display allows full spectrum scans, quantitation curves and kinetics runs to be viewed easily. The sample chamber lid can also be left open during measurements which is ideal for samples in tall test tubes.Including two USB ports for data storage and printer connectivity.Optional heated 10x10 mm cuvette holder for thermostated measurements at 37 °C.

High-quality and cost-efficient UV/VIS spectrophotometers for pharmaceutical, biochemical and clinical lab applications.Suitable for different measurement types such as kinetics, wavelength scans, quantitative analysis, multi-wavelength and DNA/Protein analysis.Available in two versions: LLG-uniSPEC 2 for standard routine measurements and uniSPEC 4 suitable for complex measurements e.g. required for quality controls. LLG-uniSPEC 4 features a small band width and a high wavelength accuracy. Both units can store and save 200 calibration curves. A pre-adjusted lamp design allows a fast and easy lamp replacement Both lamps can be individually turned on/off to extend the durability. Both versions can be used either as stand-alone units or can be operated via a PC by using the supplied software.Single beam system, grid with 1200 lines / mmSilicon photodiode detectorParallel port for printer outputUSB port4 position cell holder (10 mm) includedAdditional cell holders optionally availableLCD displayDeuterium and tungsten lampAutomatic wavelength adjustmentScope of supply: LLG-uniSPEC 2 or 4 Photometer, software for connection to PC, 4 glass cells and 2 quartz cells.SpecificationsLLG-uniSPEC 2 // LLG-uniSPEC 4Optical System:Single beam, Grating 1200 lines/mm, Silicium photodiode detectorWavelength range: Bandwidth:190 to 1100 nm 2 nm // 1.8 nmWavelength accuracy: Wavelength repeatability: Wavelength setting:± 0.5 nm // ± 0.3 nm 0.3 nm // 0.2 nm automaticPhotometric accuracy: Photometric repeatability: Photometric range:± 0.5 % T // ± 0.3 % T 0.3 % T // 0.2 % T -0.3-3 A, 0-200 % T, 0-9999 CStability: Stray light:±0.002 A/h at 500 nm ≤0.1 %T // ≤0.05 %T at 220 nm, 360 nmData output: Printer port: Display:USB port parallel port 128 x 64 Dots LCD // 320 x 240 Dots LCDStandard cell holder: Lamps:4-position 10 mm cell changer D2 lamp and W lampDimension (W x D x H): Weight:460 x 360 x 225 mm // 625 x 430 x 206 mm 18 kg // 28 kgPower supply:220 V/50 Hz or 110 V/60 HzWarranty:3 years
