Presto is made for highly precise temperature control and rapid temperature changes. The temperature control system provides large heating and cooling capacities covering a working temperature range from -68 to 121°F (-92 to 250°C). Efficient components allow fast compensation of exothermic and endothermic reactions. Laboratory users benefit from high flow rates, constant pressure and a controlled buildup of pump pressure. Changes in the temperature-control liquid’s viscosity are balanced dynamically. Permanent internal monitoring and self-lubricating pumps contribute to the temperature control unit’s long service life.
