Heidolph Rotary Evaporator Vacuum Pumps, RPM-Control

The Heidolph Rotavac Vario Control vacuum pump is a three-stage diaphragm vacuum pump manufactured with chemically-resistant components. This vacuum pump is designed for use with Heidolph Hei-VAP Precision rotary evaporators and achieves a maximum vacuum capacity of 1700-Liters/Hour for fast evacuation. Maximum vacuum pressure can be reached when working with easily condensible vapors even when the gas ballast is open. This feature makes distilling high boiling point solvents like Dimethylformamide and Dimethly Sulfoxide possible at low heating bath temperatures. These vacuum pumps can easily be combined with a condenser (see Item #: HEI-036308110).

The Heidolph Rotavac Vario Tec vacuum pump is a two-stage diaphragm vacuum pump manufactured with chemically-resistant components. This vacuum pump is designed for use with Heidolph Hei-VAP Precision rotary evaporators and achieves a maximum vacuum capacity of 1000 Liters/Hour for fast evacuation. Recommended for distillation of solvents with low or medium boiling points. These vacuum pumps can easily be combined with a condenser (see Item #: HEI-036308110.)

The Heidolph Rotavac Vario vacuum pump unit is a three-stage diaphragm vacuum pump manufactured with chemically-resistant components. This stand-alone vacuum pumping unit includes an integral vacuum controller that is fully programmable. Designed for use with Heidolph Hei-VAP Value 'Collegiate' rotary evaporators and achieves a maximum vacuum capacity of 1700-Liters/Hour for fast evacuation. Precise vacuum control avoids bumping and eliminates foaming of the evaporative sample solution. User-entered automatically-controlled vacuum pressure entry allows for unattended distillation cycle times and frees you up to tend to other laboratory work and process. These vacuum pumps can easily be combined with a condenser (see Item #: HEI-036308315.)
