Plastic Clips Testing Instruments

Plastic Clips Testing Instruments

Plastic clips are usually made of polyacetal and are colored according to joint sizes. Typical problem areas include a flask over the plate which may drop off the end of the column as it gets hot and the connection the condenser makes to the still head which will reach high temperatures and may allow the condenser to fall off. As such, different clips should be used at these points or the glassware should be clamped such that these elements can't slide apart or don't need the clip. Polyacetal clips suffer another problem in that the material is strongly affected by corrosive gases. This effect can be so dramatic that the clip will fall apart in minutes of exposure to minute quantities leaking through even greased, ground tapers. Importantly, this failure mode is sudden and without warning. The plastic clips can be tested using various testing instruments such as Plastic Clips Testing Instruments.
