SOLVES SPECTRO-ANALYTICAL PROBLEMS IN MINUTES! Bausch & Lomb

SPECTRONIC 5 0 5 RECORDING SPECTROPHOTOMETER Overall Range 2 0 0 - 8 0 0 m μ

It's simple to place samples in this 1 0 3 mm long compartment. Almost a l l standard glass­ ware is accepted by the two holders.

Light sources are easily exchanged, selfa l i g n i n g . Because they're e x t e r n a l , heat can't affect sample or instrument com­ ponents.

Lere is a fully automatic precision instrument de­ signed for fast, critical recording of transmittance, linear absorbance, reflectance and emission throughout the UV and visible ranges that costs less than half as much as similar types. It will analyze everything from ale to zinc with high accuracy, excellent repeatability, good resolu­ tion—and in record time! Even your most complex qualitative and quantitative analyses can be performed in minutes—instead of hours! The " 5 0 5 " offers many unique features. Take chart speed for example. It automatically adjusts itself to the complexity of the curve being run. Also, there are six

pre-selected scanning speeds to choose from—easily changed during the run by turning a knob on the con­ trol panel. And although the instrument is set for direct linear recording in transmittance, you can switch to linear absorbance by simply substituting a set of ab­ sorbance gears. High dispersion plus a minimum of scattered light (less than 0 . 1 % at 220 τημ) are other important ad­ vantages. There are four models, numerous accessories.
