Safer Method for Inserting Glass
Tubing into Rubber Stoppers
A safe and convenient way for inserting glass tubing and thermometers into
rubber stoppers is to insert a cork borer (AP8848) that just fits over the item to
be inserted into the rubber stopper. Thread the tubing or thermometer through
the cork borer, and then remove the cork borer. To remove thermometers or
tubing from rubber stoppers, just reverse the process.
Stoppers, Glass See page 327.
