When Do You Need an Explosion Proof Rotovap?
The deciding factor is your facility's hazardous-area classification, not the solvent alone. If the evaporator sits in a zone classified for flammable vapor atmospheres — common in ethanol extraction, pharmaceutical API recovery and fine-chemical pilot plants — codes such as ATEX in the EU or NEC Class I, Division 1/2 in the US typically require certified Ex-rated equipment. A ventilated, non-classified lab usually does not; check the rotary evaporator range if your space is unclassified.
What to Specify in Your Inquiry
Three details determine the right configuration: the solvents you run and batch volumes, the certification your site requires (ATEX category, NEC class and division, or local equivalent), and whether supporting equipment must also be rated — a recovery line pairs the evaporator with a vacuum source and chiller, which may need matching protection inside the classified zone.
FAQ
What is the difference between an explosion proof and a standard rotary evaporator?
The glassware and distillation path are essentially the same. The difference is the electrical system: motor, controls and wiring are enclosed or rated so they cannot ignite surrounding vapor. Bath heating may also change; an exposed element is itself an ignition source.
Can UnionClay match a specific ATEX or NEC requirement?
Tell us the exact marking your site engineer or insurer requires and we will confirm whether we can supply a matching configuration, with documentation, before you order.
