I'm concerned about purchasing a rotary evaporator from China. What happens if it breaks?

The EcoVap rotary evaporators have an extremely simple design. If any problem occurs, we will help you diagnose the problem remotely and Hydrion will ship you the necessary replacement part which can be easily installed.


What sizes are the glassware joints for the evaporating flask and collection flasks on the EcoVap RE-720 / RE-750?

For the RE-750, the joint for the evaporating flasks is a 125 mm flange joint and the joint for the collection flask is a 50 mm flange joint.

For the RE-720, the joint for the evaporating flasks is a 90 mm flange joint and the joint for the collection flask is a 50 mm flange joint.


What electrical connections are included on the EcoVap RE-7 Series rotary evaporators?

The motor unit uses a NEMA 6-15P plug and will draw approximately 2 amps. The bath comes with an electrical connection that does not have a plug. Hydrion does this because of the high power requirements of the large baths (up to 6 kW / 27 amps). You should affix a suitable high-amperage 220 V plug.


What size are the fittings on the condenser for the EcoVap RE-720 / RE-750

They are 15 mm fittings.
