accurate • trouble-free • time saving
Motorized ultramicro buret, the DlgiPet Moto-Buret, dispenses and meas ures liquids in the laboratory at an accuracy of up to 0 . 1 % of dispensed volume, with a sensitivity of up to 0 . 0 1 % . The buret operates on a standard 115 volt, 60 cycle power source. Displaced volume can be read directly to four decimal places from a digital counter which has a push-button reset.

" • CONTINUOUS-FLOW ELECTROCHROMATOGRAPHY THAT'S FAST, EASY, EFFICIENT, ACCURATE
THE CR-1 IS A RESEARCH NECESSITY FOR C O N T I N U O U S SEPARATION PURIFICATION AND COLLECTION UNIQUE FEATURES OF THE CR-1 • Increased power for greater resolu tion in separations. 3, 000 ν at 200 ma providing reliable and precise temperature, voltage and amperage control. • Integrated refrigeration system (an engineering advance in itself) with automatic defrost, invaluable for long, continuous runs. • 27 to 54 fraction collection points. • Reliable and constant control of elec trochemical heat transfer and elec tronically related equilibria,
The Disc Integrator provides a Trace readout which is automatically and continuously recorded on the side of the chart. Valuable time is saved in chart evaluation. The integrator is par ticularly applicable to gas chromatog raphy but can also be used to integrate any variable. In addition to the Trace, a readout can also be displayed on a manually controlled counting register. Price $585.00—Integrators are avail able for most recorders. For ordering information, contact your local recorder manufacturer or write direct to Disc Instruments, Inc.

Reichert of Vienna, Austria, features an entirely new ball-bearing single control focusing system. For coarse focusing a dual positioned knob is turned, while fine adjustments are made by shuttling this knob. In addi tion to faster, more convenient fo cusing, the new system eliminates backlash. The interchangeable in clined binocular and monocular ob servation tubes are rotatable through 360°. William J. Hacker & Co., P. O. Box 646, West Caldwell, N. J. 07007. 422
