Accuracy is easy with... the compact Zeiss PM 6 Spectrophotometer with double-grating monochromator and automatic blank reference.
3.000 Absorbance and 0-10,000 Concentration, and expand the scale 10X with great accuracy. Spectral range is 2 0 0 8 0 0 n m with high photometric linearity.
It's so simple, it's foolproof. All you do is: 1 put your blank in the first position; 2 place samples in the other three positions, or a known standard in the # 2 position; 3 set the display to absolute absorbance or the desired concentration value; 4 push the button for the sample position you want, and the results will be displayed directly either in absorbance or concentration. Kinetic determinations are just as simple.
No other instrument in its price range offers a double-grating monochromator.
And it's accurate. You can sample volumes f r o m 2 0 m l to 0.2ml without loss of sensitvity. Read out digitally f r o m —0.300 to
