Rotary Evaporators

A rotary evaporator built for precision, safety and everyday reliability in the lab.
Compact and powerful, the series turns routine distillation into a faster and safer process.

A key element of modern labs

When the American, award-winner, chemical researcher Lyman C. Craig invented the rotary evaporation system in 1950, probably he could not imagine what an innovation he brought into the chemical and pharma industries. This system has even found application in molecular cooking.
Compared to a static apparatus, a vacuum rotary evaporator carries out single-stage distillations quickly and gently. Its capacity is generally about four times greater than conventional static distillation. That’s why it’s so widely used. It concentrates solutions, removes solvents and separates low- and high-boiling or solid residues.
The concentration of solutions by distilling the solvent and getting rid of low and higher-boiling or solid residue is a necessary step in organic synthesis and extracting inorganic pollutants. Evaporators are also used outside research laboratories such as chemical, pharma, petrochemical and food industries.

The ideal partner for laboratory evaporations

LabTech’s rotary evaporators bring a new standard to routine distillation and evaporation: safer, more efficient and built to last.

The EV series pairs an innovative, ergonomic design with a color digital display for rotation speed and temperature, a motorized vertical lift, and online sample addition through a PTFE valve.
A stand-alone heating bath keeps operations safe and maintenance simple.

Technology and design

Repeatable results start with control. The EV series gives you:

  • Digital control of rotation speed, with temperature displayed on a color screen, for accurate and stable operations
  • Pre-loaded solvents library, so you can start with the right settings faster
  • Online sample addition through a PTFE valve, so you can keep working without interrupting the process
  • Vertical or diagonal column, depending on your setup
Built to last

Every component is selected and tested to handle the daily demands of a working lab, from aggressive chemicals to high temperatures and constant use. The result is an instrument that stays reliable run after run, year after year.

  • Trouble-free operation and long lifetime
  • PTFE seal loop ensures excellent elasticity, resistant to acids and solvents even at high temperatures
  • Innovative and durable design that prevents corrosion and splashing
Safety at every step

Your team’s safety comes first. The EV series adds protection where it matters:

  • Stand-alone heating bath guarantees maximum safety and easy maintenance
  • Automatic lift-up protection in case of electric power failure
  • Thermostatic bath with temperature control from room temperature up to 230°C
  • Anti-corrosion, anti-splash design
Easy to use, easy to maintain

Installation is simple, handling the flasks is easy and routine maintenance doesn’t require hours of disassembly. Every detail is designed to make your daily work easier, so you can focus your time on the results.

  • Motorized vertical lift (depending on model) for effortless flask positioning
  • Wide range of evaporation flasks for different volumes and applications
  • Removable front panel for quick access and simple servicing

Plastic-coated glassware: extra protection, on request

In rotary evaporation, glassware is absolutely essential… but also the most fragile part.

That’s why we developed the plastic-coated version of LabTech Rotary Evaporator: a safer, stronger and more durable solution. In this version, glassware is equipped with a special coating that holds fragments together and minimizes damages in the event of accident.

The plastic coating acts as an added layer of protection, reducing the risk of damage and the need for frequent replacements. It improves safety of scientists and technicians in every laboratory.

In the event of glass breakage, the coating helps to contain the shattered pieces, minimizing the chances of glass fragments scattering and potentially causing harm to the operator or contaminating the experiment. This added safety aspect is crucial in laboratory environments where personnel work with hazardous substances or volatile compounds.

The coating is highly transparent and can resist up to 90°C. Available for condensers as well as evaporating and receiving flasks.
