Safety Information

Safety Precautions

If the motor overloads - stop operation immediately.

If you continue operation under abnormal overload conditions, the motor may stop by the safety device. If the motor stops, turn the volume knob to the minimum and cut the switch off.

Overload means the situation when the motor surface heats up more than 90 due to

rust on ball bearing etc.,

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

Make sure that the volume knob is at “min”. If the volume 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 volume knob to the minimum.

Never fail to ground the unit.

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

Be cautious using 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, cut 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.
