Viscosity Recording
New Products
The Brookfield recording Viscometer is a comprehensive system which gives a permanent record of viscosity and/or temperature as a function of time. Four measuring options are available: • Standard Brookfield disc or cylinder spindles.
• Coaxial cylinder spindle and chamber — a defined system using small samples. • Cone/Plate for absolute shear rates using micro (1 ml) sample volumes. • Thermosel for measurement at elevated (500°F) temperatures. Optional electronic or pneumatic recorder.

The Evapplicator permits single oper ation concentration and spot applica tion to chromatographic media, as well as evaporation rate and spot size con trol. The triparameter control system regulates air or gas flow rate, air or gas temperature, and adjustment of Tef lon application capillary. Channel-tochannel spotting reproducibility is 11.5% in the totally self-contained sys tem. Manostat Corp. 410

IR Detector
RECORDING BALANCES with a little something entra
A new highly sensitive Golay-type in frared detector with nonselective wavelength range of 0.5 μ to 1 mm fea tures sensitivity of 1.5 Χ 106 V/W and noise of only 7 Χ 10" 1 1 W. The detec tor head (2.4 X 3.58 X 4.25 in.) houses the gas chamber, the optical readout system, and the amplifier. Model 7500 is designed with a safety feature to prevent changes in ambient tempera ture from affecting the detector. Oriel Corp. 438 Laboratory Furnace
