The pump piston has been designed with a smaller diameter so that the handle can be pulled out with even less effort. The pump body is covered with a soft elastomer, The pump is make of non-sparking materials of ABS resin

Light-Pull Handle
The full-stroke(100ml) and the half-stroke (50ml) positions are marked exactly by the red line on the pump shaft, and the handle is precisely locked at those positions.

Improved Flow Finish Indicator
The attached flow finish indicator tells you automatically when the stroke is complete. When the white disk pops out, the sample is complete.
