・ By reducing the cross -sectional area in a conical shape toward the lower PTFE cock, liquid separation can be performed more efficiently than spherical.
・ Because the liquid plug is an SPC standard, unlike a general grinding tube of a general arrangement (transparent), it is possible to connect a dense and dirty no grease.
・ Since the lower end is a compatible SPC standard, the drip solution can be efficiently recovered by connecting to the same S socket -shaped container.
