Densitometer DEN-600

Compact and efficient benchtop densitometers for measuring turbidity of cell suspensions in a variety of life science applications. The densitometers are designed and factory calibrated to measure turbidity in the range of 0.3 to >7.5 McFarland units (DEN-1) 0.00 to >15.00 McFarland units (DEN-1B) with a small standard deviation.SpecificationsLight source: Wavelength:light diode 565nm ±15nmMeasuring range DEN-1: Measuring range DEN-1B:0.3 to 7.5 McF 0.0 to 15.00 McFPrecision:±3%Measurement time:1secTubes diameter, external: Tube diameter with D16 adapter (included):18mm 16mmSample volume: Dimensions (W x D x H):≥2ml 165 x 115 x 75mmPower supply:12V (DEN-1B additionally 3 x AAA batteries)

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.
