Safety Information

Safety Precautions

If the motor overloads - stop operation immediately.

If you continue operation under abnormal conditions, the motor will stop automatically. If the motor stops, turn the control knob to the minimum and turn off the power switch.

Overload condition exists when the motor surface temperature reaches more than 90 .

A cause of motor overheating is seized ball bearings.

Make sure that the volume knob indicates “min” before turning the unit on.

Make sure that the control knob is at “min”. If the control knob is not turned to “min”, the evaporation flask turns round when you turn on the power switch.

Move the lift up or down after you stop rotation of the evaporation flask.

If the lift is moved up or down while the evaporation flask is rotating, scalding may occur due to dispersing of hot water. Be sure to move the lift after turning the control knob to the minimum.

Never fail to ground the unit.

This unit uses a 3-conductor power cord (including ground wire). Be sure to ground the unit for safety.

Flammable chemicals

This unit is not explosion proof. Do not use in flammable or explosive gas environments and do not evaporate explosive substances.

The flask clamp is very springy. Be careful not to break the glass apparatus.

The enclosed flask clamp is very springy to hold the glass apparatus firmly. Be careful not to break the glass.

Safety Information

Safety Precautions

Only water to be used with the Water Bath.

Only water in the Water Bath. Problems can occur if anything other than water is used. Also be sure not to heat with low water level or the bath can overheat.

Use a trap.

Use a trap when you decompress by hydraulic rotary vacuum pump. When you use our Handy Aspirator, fill to overflow.

Maintain the vacuum seal.

The vacuum seal is expendable. Exchange the seal in case of vacuum-down.

You can use the vacuum seal without grease. But you desire more longer life of the seal, put silicon grease onto the ripped side of vacuum seal. If you are afraid of sample contamination, use liquid sample.

Cleaning the exterior of RE series evaporator

Do not use any volatile chemicals to clean the exterior of this unit. This could damage the color and shape. Wipe clean with a soft dry towel , etc.-Do not use a brush.

If the unit is not in use for a long period of time, disconnect the power supply.

If the unit is not in use for a long period of time, turn the power off and pull out the power cord for safety.
