Manual vacuum pump for gas detection tube

The Japanese Guangming Chemical Gas Pump AP-20 is specifically designed for extracting gases from gas detection tubes. There are two extraction modes: 100ml and 50ml. Can extract 100ml and 50ml of gas at once.

When the gas intake is large, the handle of the hand pump can be retracted to extract gas again. The pump body itself has a cutter that can cut the end of the detection tube. Save the cost of purchasing specialized cutters.

At the same time, the pump itself has a red timer at the top, which can automatically pop up the timer when extracting gas. No need for specialized timers such as watches. Can be timed for multiple gas extractions.

Finally, AP-20 has a broken glass storage container that can store the broken glass at the end of the cut detection tube to prevent injury.

The AP-20 gas collector produced by Guangming Chemical Industry Co., Ltd. in Japan is a device with excellent airtightness. It creates negative pressure through the movement of the piston inside its internal cylinder, and sucks in the detected gas through the detection tube.
