Care & Maintenance of Laboratory Glassware
To obtain the maximum performance from your laboratory glassware correct handling is essential. The following information is a guide on the safe handling of glassware and tips on how you can optimise its performance and life span.
Heating and Cooling
Vacuum and Pressure Use
Because working conditions can vary enormously, DWK Life Sciences cannot guarantee the performance of any of its glassware when used under vacuum or positive pressure. The application of positive pressures inside glass apparatus is particularly hazardous and should be avoided, if at all possible. Safety precautions should always be taken to protect personnel and a number of these are listed below:

To prevent joints leaking in use and to assist separation, lubricate the ground surfaces of the joint with a silicone-free laboratory grease. Apply a light coating completely around the upper part of the joint. Alternatively, a PTFE sleeve can be fitted between the cone and socket.
If ground glass joints do seize, we suggest the following remedies to separate the joint:
