Thermodynamic Power from Julabo
Mar 13 2018 Read 718 Times
Julabo’s PRESTO represents the state-of-the-art for modern laboratories. These instruments cover a working temperature range of -92°C to +250°C with high cooling and heating capacity. Maximum heating capacity can also be adapted to fluctuations in the mains power supply. Highly efficient components give these instruments the ability to compensate for exothermic and endothermic reactions with extraordinary speed. The PRESTO units are extremely robust and work reliably even if the ambient temperature climbs as high as +40°C. The integrated cooling machine and an internal, cooled expansion vessel absorb volume changes in the heat exchanger.
Power to the pumps
Magnetically-coupled pumps in the PRESTO units are powerful and maintenance-free. Lab users benefit from high flow rates, constant pressure,
and a controlled build-up of pump pressure. Changes in the temperature-control liquid’s viscosity are balanced dynamically. Permanent internal monitoring and self-lubricating pumps contribute to the PRESTO’s long service life. The operator can adjust pump capacity by selecting one of four stages or by entering a specific pressure. Once entered, the pressure value will be maintained throughout the entire process. The closed pumping loop isolates the heat transfer liquid from ambient air, preventing penetration of moisture and oxidation. At the same time, this design ensures that the PRESTO will not emit oil vapour.
Raising the bar on user friendliness
The integrated 5.7-inch industrial colour TFT touch screen is one of the identifying characteristics of the PRESTO. It gives the user a clear and well-organised view of important information while greatly improving user-friendliness. Fingertip control via the new touchscreen makes it incredibly easy to operate the PRESTO units.
International users can choose from eight different languages. Three different views of important information are provided by default and may be adapted by the user at any time.
Password management for one administrator and up to two additional levels of authorisation makes it easier to manage laboratory procedures. For example, an administrator can set common parameters in advance and then restrict other employees' access rights so they are only able to retrieve the pre-set parameters.
