The barrel plunger BTA series is used to ensure that the pressure is spread evenly across the fluid surface to provide consistent dispensing. They prevent air entrapment and ensure no material residue is left on the syringe barrel walls by wiping the syringe barrel wall clean with its precision wiping edges during dispensing. The barrel plungers are recommended for difficult materials whose properties could cause problems with the barrel plunger BT series. The parts that make contact with fluids are made of aluminium and FKM, thus they have excellent chemical resistance. It is sold individually.
