Mechanical Convection Oven Temperature controlled laboratory ovens are available from Precision Scientific Co. Temperature range is from 125° to 1000° F. and temperatures can be kept uniform throughout the working chamber at ±1° at 125° and ±6° at 1000°, because of controlled air flow. A direct-reading pyrometer indicates temperature. Interior is of stainless steel and exterior of polished stainless steel or baked enamel. P-14

THE NEW BECKMAN COMBINATION ELECTRO t>E.

Dual-Purpose Bath The dual-purpose bath, produced by American Instrument Co., can be used as a controlled constant temperature bath or for circulating controlled temperature liquids through external apparatus. The bath contains both refrigerating and heating elements and its temperature range extends from —29° to +71° C. with constancy ranging from

This is the 'working" end...

The instrument is capable of extreme accuracy, says the manufacturer, in producing simultaneous linear and logarithmic plots. It is said that the counting statistics themselves usually limit the accuracy of the determination. P-16 Capillary Tubing Superior Tube Co. can supply capillary tubing in lengths up to 3000 feet, with flow rate tests. Capillary tubing is defined as tubing 3 / i e inch or less in outside diameter. Superior Tube generally furnishes it made from stainless steel, carbon steel, nickel, Monel, or Inconel. Flow rate testing is performed if required. Test reports are in terms of cubic centimeters per minute of nitrogen gas flowing through a length of tubing under a given pressure. The tubing is furnished in random, multiple, and cut-straight lengths up to 39 feet and in coils up to 3000 feet, with the long lengths wound on reels. P-l 7

The Combination Electrode offers unbeatable convenience. Several types are available now for a ' wide range of surface and solution measurements, titrations and redox determinations. They can be used with all Beckman pH meters, including models G, GS and the Zeromatic*.
