DrySyn

Heating systems

The new DrySyn system, from Asynt, Cambridgeshire, UK, can satisfy a wide range of temperature control requirements in the chemistry laboratory, from heating a single flask to creating a parallel subambient reaction station. DrySyn systems are available for single- or multiple-reaction vessels with volumes from 1 mL to 5,000 mL. All models feature a compact footprint and are fully compatible with magnetic stirring, and the novel Vortex Overhead Stirrer System can provide powerful directly driven stirring for up to three flasks, improving performance with viscous mixtures and largely eliminating the grinding effects that can occur with magnetic stirrers on solids, especially crystals.

Scroll Vacuum Pump

Pulse-free operation

The new three-stage compact scroll vacuum pump (CSVP), from Air Squared, Broomfield, Colo, can produce up to 5-mTorr (6.5 by 10-6 atmosphere) vacuum without a turbo pump. With a package size of just 7.5 x 5.9 x 5.7 inches, the oil-free CSVP can replace a turbo-boosted pump to save weight, space, cost, and maintenance in applications ranging from spectrometers and gas detectors to analyzers, autoclaves, and lab vacuum stations. Its rotary scroll design provides quiet, pulse-free operation. Power delivery is continuous, helping to eliminate pulsation and associated noise.

Pinch Valves

Controls fluid handling systems

Providing effective control of flow paths for fluid handling systems, Bio-Chem Fluidics Boonton, NJ, introduces its newly redesigned solenoid operated pinch valves. The 075P2 two-way valves have low power requirements and are available with a normally open or normally closed valve function. The new design eliminates sharp edges, with smooth contours that allow easier insertion and removal of tubing without snares. An integrated insert provides both positive tube retention and confirmation of correct tubing size. Manual push-button override is also available. The new design incorporates both Luran and Ryton—materials resistant to most common cleaning solutions.
