You also get more features at less cost with Sequoia-Turner spectro­ photometers and fluorometers. Advanced electronics. Superior optics. Compact design. Extended wavelength range. The Model 450 Fluorometer provides higher sensitivity, low drift and ease of use. Concentration range is 0 to 1999 and wavelength range is 350 to 650nm (extendable to 750nm). The Model 390 Spectrophotometer has concentration, absorbance, factor and transmission modes. A diffraction grating monochromator ensures a wavelength range of 330nm to 1000nm and can be expanded to 210nm with a Far UV accessory. The Model 340 is available with absorbance and transmission modes at an even lower cost. The MTBF for these instruments is 21 Vfe years, based on a study of the first 1000 units in use. This means less down time and little, if any, maintenance costs... a feature enjoyed by Turner instrument users for the past 25 years.
