Choosing Equipment Falling Film vs Wiped Film Evaporators for Solvent Recovery

October 22, 2026 6 min read

If you recover ethanol or other solvents from large volumes of flavour and botanical extracts, a rotary evaporator eventually becomes the bottleneck. The next step up is a thin film evaporator. The two designs you will hear about most are the falling film evaporator and the wiped film evaporator. Both spread liquid into a thin layer on a heated surface so solvent evaporates quickly. They do it in different ways, though, and that difference decides what each one is good at.This guide explains how each works, [...] Read the guide › Choosing Equipment Choosing a Rotary Evaporator Size: 2L, 5L, 10L, 20L or 50L?

Rotary evaporator size is one of the first decisions on any quote, and one of the easiest to get wrong. Buy too small and the unit becomes a bottleneck. Buy too large and you pay for bench space, power and glassware you never fill. This guide explains how a rotovap actually removes solvent, why the number on the flask is not your working volume, and how to match a 2L, 5L, 10L, 20L or 50L system to your batches for solvent recovery, essential oil concentration and flavour work.How a Rotary Evaporator WorksA [...] Read the guide › Choosing Equipment Dry Scroll vs Rotary Vane vs Diaphragm Vacuum Pumps for the Lab

October 22, 2026 7 min read

Most lab vacuum questions come down to three pump types: diaphragm, dry scroll and oil-sealed rotary vane. All three will pull a vacuum on a rotary evaporator, a distillation setup or a vacuum oven. They do it in very different ways, and that changes how deep they go, how they cope with solvent vapour and what you spend your time maintaining. This guide explains how each one works, then matches them to common jobs, with real catalogue examples so you can compare data sheets side by side.How Each Pump Create [...] Read the guide › Choosing Equipment Short Path vs Wiped Film Distillation: Which Suits Your Process?

If you purify essential oils, flavour extracts or other natural products, you will eventually ask whether to start with a glass short path kit or invest in a wiped film system. Both are vacuum distillation tools that separate compounds by volatility. They differ in how long your material sits on a hot surface and how much of it you can process in a shift. Here is how each one works, where each makes sense and what you need around them.The Principle Both Share: Vacuum Lowers Boiling PointsA liquid boils when [...] Read the guide › Choosing Equipment Single vs Dual Jacketed Glass Reactors and How to Match a Chiller

A jacketed glass reactor controls temperature through its jacket and the circulator feeding it. For crystallization, controlled cooling and low-temperature synthesis, the two main choices are whether the vessel has one jacket or two, and which recirculating chiller will drive it. Get both right and you hold setpoint, see your batch and protect the glass. Get them wrong and you have a fogged vessel, a chiller that never reaches temperature, or a cracked jacket. Here is how the parts work and how to match the [...] Read the guide › Choosing Equipment Choosing a Heat Transfer Fluid for Your Chiller or Heated Circulator

October 22, 2026 7 min read

The fluid in your chiller or heated circulator does the real work. It carries heat out of a reactor jacket, condenser or cold trap, or carries heat into it, and then returns to be cooled or reheated. The wrong heat transfer fluid for a chiller or circulator can freeze, turn too thick to pump, boil, smoke or degrade. The right one is easy to forget about. This guide covers how to match a fluid to your temperatures and equipment, and how to fill and change it safely.How a Heat Transfer Fluid Works in the Loop [...] Read the guide ›
