EV400 rotary evaporator system with digital vacuum controller

Laboratory Equipment · 3 models

A rotary evaporator is a system, not a single box. LabTech supplies the EV400 range as a complete solution: the evaporator with its PTFE and KFM seal set, the heating bath, and a digital vacuum controller that holds the pressure the method needs. That last part is what makes a distillation reproducible, because boiling point follows vacuum, and a controller that sets vacuum by number runs the same method the same way next month.

One complete system

Evaporator, heating bath and digital vacuum control specified together, so a method stays reproducible.

Seal built for solvents

A PTFE and KFM seal system resists aggressive solvents and holds vacuum through long use.

Four EV400 configurations

Manual, touchscreen, EV400H and EV400 Vac share one platform and one 51 lb footprint.

Pilot scale ready

The YRE-2020Z takes a 20 L flask with 5,000 W of heating and a 10–120 rpm drive.

Models

Choose the configuration.

The EV400 platform covers most benches in four configurations: manual EV400, touchscreen EV400 Touch, the EV400H, and the vacuum-controlled EV400 Vac. All four use a 20–300 rpm drive, a PID-controlled bath to 180 °C and 1,300 W of heating in a 15 × 14 × 28 in frame. For pilot scale, the YRE-2020Z takes a 20 L flask at 10–120 rpm with a 5,000 W bath.

EV400 platform

Benchtop rotary evaporator platform

The EV400 pairs a 20–300 rpm drive (20–260 rpm on the EV400H) with a PID-controlled bath that reaches 180 °C and 1,300 W of heating, in a 15 × 14 × 28 in frame. Four configurations differ in control and vacuum: manual EV400, touchscreen EV400 Touch, EV400H and the vacuum-controlled EV400 Vac.

Digital vacuum controller

Digital vacuum controller for reproducible distillation

A controller that sets and holds system vacuum digitally. Because boiling point tracks pressure, a vacuum set by number rather than by eye gives the operator a defined distillation and a repeatable one. It is the component that turns a rotary evaporator into a method that can be written down and handed to another analyst.

Digital setting and control of vacuum in the system
Gives the operator a defined, measurable distillation
Improves run-to-run reproducibility
Supports methods with the strictest reproducibility requirements

Questions

Before you buy.

What does a complete EV400 rotary evaporator system include?

The system is supplied as an evaporator, a heating bath and vacuum control, configured together rather than as separate parts. The basic EV400 gives manual one-handed lift and shuttle-key speed setting with a PTFE and KFM seal. The smart EV400 adds a color touchscreen, a built-in solvent database and automated distillation, with a precision digital vacuum controller holding the set point.

Do I need the digital vacuum controller?

It is what makes a distillation repeatable. The controller sets system vacuum digitally, and because boiling point follows pressure, the operator works to a defined number instead of judging by eye. That improves control over the run and supports methods with the strictest reproducibility requirements, which is why it completes the EV400 system.

Which EV400 configuration should I choose?

Choose the basic EV400 for routine concentration where an analyst adjusts the run by hand. Choose the smart EV400 when several solvents are in rotation: its touchscreen holds a solvent database, one key starts a stored method, and the system identifies boiling point and captures the best parameters automatically. Both configurations cover concentration, distillation, purification, separation and drying.
