ISCC) UV absorbance monitors offer youall this (except the partridge, etc.) andmore. Linear absorbance recording.Stable circuitry. Built in recorder. Nar-row bandwidth. And by far the lowestcost of all high performance monitors.

These instruments can monitor two col-umns at once (or one column at twowavelengths). They operate at 254 nm,280 nm, orother wavelengths to '50 nni.The ISCO Peak Separator will put eachpeak in a different test tube, and an ISCOintegrator will print out peak areas.

These are some of the reasons ISCO UVabsorbance monitors have been so popu-lar for years. Thousands are in usethroughout the world. Write or call forour catalog describing these monitors, aswell as ISCO fraction collectors and manyother instruments for biochemicalresearch.

The new 9785 is available either

with quartz envelope, or UV en-

velope as types 9785QB and

9785B respectively. They are

fitted with the standard B-11-88base and are directly inter-

changeable with all similar typeseither from EMI or other manu-

facturers. Carefuli design andrigorous manufacturing controls

insure excellent long and shortterm stability. The wide spectralrange together with the high gainat low overall volts and the low

dark current of these types make

them eminently suitable for new

instrument design or upgradingexisting instruments. Their fast

time characteristics also make

them suitable for detecting fast

laser pulses. For applicationswhere high Q.E. in the visible

region only is required, the 9781 B

is available. The 9783B with

quartz window gives a usefulrange to 165 nm.
