FAQ

Does the LabTech EV311H come with glassware?

In addition to the selected condenser, all LabTech rotary evaporators come with a 1 liter collection flask, a 1 liter evaporating flask, and a 29/32 joint size vapor tube.

 

What is the minimum pressure the system will support?

EV311 series rotary evaporators can support an ideal minimum pressure of 0.0002mbar. However, most vacuum pumps don't have that low of a pressure capability so the minimum vacuum will most likely be limited by the vacuum pump you use.

 

What size tube is needed to attach to the cold water coil and vacuum ports on the condensers?

The condensers come with GL-14 thread size hose barbs which can accommodate tubing of 1/4" inside diameter.

 

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

LabTech has offices, including a warehouse and repair facilities, in Hopkinton, Massachusetts. If you experience any issues with your equipment which require repair, it will be performed by their staff in the United States.

 

I'm using an aggressive solvent and want to ensure it will not degrade the sealing ring. What is the sealing ring made of?

The sealing ring on all EV311 rotary evaporators is made of PTFE + FKM.

 

Is the LabTech EV311H UL certified?

No, the EV311 series of rotary evaporators are not UL listed.

 

What is the amperage of the EV311H rotary evaporator?

The EV311H requires 15 Amps.
