คุณลักษณะ

• Handy oil pump that draws non-viscous liquid into a dedicated bottle by manual piston operation.
• Water can be collected from bottles, tanks, barrels, drums, etc., with a minimum diameter of 1.5 cm, and is also suitable for water collection from well water, groundwater, and cisterns as it has a suction force of about 5 m from the liquid surface. However, it is not suitable for sampling water from sources containing garbage or impurities.
• Since the water sampling liquid enters the bottle directly from the tube without going through the aluminum pump cylinder, there is no need to clean the inside of the cylinder. Moreover, the tube and bottle can be easily attached and removed by simply twisting.
• General pumps have a release valve on the head, and when the required amount of water is collected, the pressure is released and the liquid in the tube is released.
• Glass bottles of screw standard GL45 (sold separately) can be connected with the conversion adapter for GL45 glass bottles sold separately.
• < Water sampling method >
• 1.Screw the bottle firmly into the head.
• 2.Insert one end of the tube from the tube fixing screw side through the head until it is 2~3 cm into the bottom bottle and tighten with the tube fixing screw.
• 3.Put the other end of the tube into the sampling solution.
• 4.When the piston is moved back and forth, the sampling liquid flows directly into the bottle through the tube.
• 5.After sampling the required amount of water, push the release valve to stop the inflow and return the liquid in the tube (however, there is no release valve for the large diameter).
• 6.Loosen the tube fixing screw little by little to confirm that the liquid in the tube is gone, then remove the tube and remove the bottle.
