Rotary Evaporators

Rotary Evaporator (Rotovap) - 5L to 50L Lab Distillation Units

Rotary evaporators are the standard solvent recovery tool across cannabis processing, pharmaceutical R&D, essential oil and chemistry labs worldwide. LM Scientific's R Series covers 5L, 6L, 10L, 20L and 50L evaporating flasks with matched receiving flasks, patented PTFE dual spin seal for high vacuum, accurate bath temperature control, and both regular and explosion-proof configurations. Customers typically pair our rotovaps with circulating chillers and vacuum pumps for complete ethanol winterization and solvent recovery workflows.

Catalog Highlights

What the product catalog adds

These points are drawn from the supplied LM product catalog and turned into buyer-facing detail.

PTFE and fluororubber dual spin seal design for deeper vacuum and cleaner solvent recovery.

Accurate bath temperature control with continuous receiving during distillation workflows.

Regular and explosion-proof configurations appear in the catalog, matching solvent-heavy applications.

Buying Guidance

How to specify the right system

Premium instrumentation decisions should account for methods, workflow and lifecycle service before the purchase order is issued.

Sizing & throughput

Choose evaporating flask size based on batch volume — 20L and 50L are the most common for cannabis ethanol recovery.

Compliance & hazloc

Specify explosion-proof configuration if the unit will operate in a C1D1 or C1D2 (or equivalent local) hazardous environment.

Power & utilities

Confirm 110V or 220V single-phase supply — a step-up transformer is often required for 110V sites running the 50L unit.

Buyer Notes

What usually matters during internal approval

These points help procurement and engineering move from browsing to approval without the usual back-and-forth.

Confirm whether the installation is a non-hazardous room, C1D2 or C1D1 before quoting explosion-proof scope.

Chiller sizing often controls actual throughput more than flask size alone, so we'll size both together.

If the unit is for workplace use, buyers may ask for documentation beyond CE; address that in the quote package.

Request a quote with process, utility and destination data.

Include the target application, solvent or media, batch size, required temperature or vacuum range, facility power, hazardous-area requirement and destination ZIP code.
