RDVT-01 Vacutainer blood collection vessel pump volume tester Applies to the pumping volume of blood collection tube and it can accurately Measure whether the drawing volume meets the standard in different elevations. 

 the Testing principle of blood vessel suction volume tester is shown in the figure below:

the testing Tube is inserted into the test system, so that it is consistent with the Pressure in the left tank. Then according to the elevation of blood tube Application, the tester will create different pressure value. after waiting for One minute for the pressure to stabilize, the weight of tube before and after Test is compared to determine the drawing volume.  

  

RDVT-01 Vacutainer blood collection vessel pump volume tester is convenient in use, digital input, and the system will automatically keep Constant pressure in accordance with the change of liquid level in the tank, so as to guarantee the accuracy of the test.
