Closed Circulator Systems

Supplier: VWR Collection

VWR® recirculating chillers are ideal for use with rotary evaporators, as they ensure constant, reproducible cooling conditions and avoid wasting tap water thereby increasing cost savings. Designed to be user friendly, the units have an easily accessible filling port on top of the unit and a drain tap at the back. The chillers have a stainless steel reservoir, operate using R134 refrigerant and can be used in the permitted ambient temperature range of 15 to 32 °C.

Stainless steel baths with user friendly MX temperature controller plus three control buttons and on-screen prompts. Baths can be used for external closed loop circulation. The controller rests on a chemically resistant DuraTop™ deck, which is cool to the touch, even when working at high temperatures, and units feature LidDock™ lid stowing system. Cool Command™ technology regulates the amount of cooling required, saving energy while providing rapid cooling and precise control at elevated temperatures.

The compact AWC100 air to water recirculating cooler is designed to remove small heat loads from external systems where cooling water can be above ambient and where temperature control is secondary. Coolers which do not have a refrigeration unit are ideal for use in circuits with Peltier elements, analytical devices, polarimeters, refractometers and CCD cameras. The ventilator speed (i.e. the cooling capacity) can be adjusted in two stages, cooling capacity depends on the temperature difference between return line temperature and ambient temperature. The cooling principle: Warm bath fluid is pumped through the heat exchanger. The heat exchanger is cooled by a ventilator motor and thus removes the produced heat.

Temperature Control Unit, 2 L

Supplier: JULABO GmbH

Compact refrigerated/heating circulators which can be used on benchtop or in a fume hood, ideal for temperature control of distillation apparatus or mini plant installation. All four models feature pump connections for external temperature applications and a bath opening for temperature control of small objects directly in the circulator bath. The maximum ambient temperature of +40 °C and air cooled ventilation means the units can be positioned alongside other units or directly in a fume hood.

Sonication generates heat which may be detrimental to some applications. Attempting to control temperature with ice and/or repeatedly changing out water is tedious and no longer necessary. This chiller automates the sample cooling process.

Supplier: JULABO GmbH

Compact, ergonomically designed chillers which have integrated stainless steel tanks with large volumes. Models can be either air or water cooled. Applications include use with rotary evaporators, autoclaves, reaction vessels and for routine laboratory cooling. All units have an LED temperature display for actual/set point integrated into a splash-proof keypad and recessed grips for easy relocation integrated in the housing. A hinged tray serves as a compartment for the operating manual and other documents. The removable venting grid allows for easy cleaning of the condenser. Venting slots are located on the front and back, allowing units to be placed directly next to each other. Models FL2503 to FLW11006 have an early warning function with sensor monitoring to signal if the condenser is dirty, and online diagnostics with 'BlackBox' function.

High temperature circulators can be used for temperature applications up to 400 °C; units provide powerful heating capacities for shortest heat-up times and rapid compensation of endothermic reactions. Applications include use with reactors, autoclaves, distillation columns, mini plant installations, pilot plants and production facilities. Because of the closed circuit system oxidation is reduced and unpleasant odours and vapours do not escape, even at high temperatures.

PRESTO® systems cover a working temperature range of −93 to +250 °C with high cooling and heating capacity. These instruments can compensate for exothermic and endothermic reactions with extraordinary speed, they feature high flow rates, constant pressure and a controlled build-up of pump pressure. Changes in the temperature control of liquid viscosity are balanced dynamically. Permanent internal monitoring and self-lubricating pumps contribute to long service life. The integrated touch panel gives the user a clear view of important information. Fingertip control via the touch screen. Multiple interfaces enable remote control of the PRESTO® across networks and in super-ordinated control systems. Wireless remote control of the new PRESTO® can easily be done by using the Wireless TEMP range of products.
