Model 09722

The specimen tube, model 09722, is intended for the determination of rammability and bulk density according to GOST 23409.13-78. The specimen tube operation principle is the production of a sample for the mixture which is poured into the tube and squeezed with the impact testing device.


A specimen tube consists of the actual tube and a mold base. A mold base is used as a specimen tube bottom when it is filled with mixture. The specimen tube is used in molding materials workshops and factory laboratories and research institutions laboratories.
