This is a combination of a small vacuum pump and a suction selector switch.
Adsorption can be turned on and off without depending on the power switch of the vacuum pump.
A suction switch and one 2 m air hose (outer diameter φ6 mm, inner diameter φ4 mm) are included.
*Connect the ON side of the suction selector switch to the vacuum pump with an air hose.
*Please prepare the air hose from the suction switch to the suction destination by yourself.
*Can be used with vacuum adapter VA-631/931/131 (adsorption power may be insufficient depending on the conditions of the sample to be adsorbed).
