Warnings

Operator safety is the top important issue! Please operate the equipment with cautions. Working with inflammable& explosive or toxic gases is very dangerous, operators must take all necessary precautions before starting the equipment. Working with positive pressure inside the reactors or chambers is dangerous, operator must fellow the safety procedures strictly. Extra caution must also be taken when operating with air-reactive materials, especially under vacuum. A leak can draw air into the apparatus and cause a violent reaction to occur.
