It can be connected to either side of the vacuum line of LH-87 or LH-88. A is a cold trap body and is constructed by two ball-grinding ports. The B nozzle is a 57mm flange with a clip for the O-ring and 57mm flange. C has a vacuum valve door of 0-8mm. The vacuum valve door of D is 0-8mm, and is connected with the B tube by a 57mm flange. H is a vacuum valve tube of 0-4 mm, and a 9 mm branch pipe behind the tube. The ball grinding port at G is connected to the A of the main body cold trap. The real door valve door with F of 0-8mm is connected to the A tube as a main body cold trap. The high-vacuum valve of the all-inclusive ring is corrosion-resistant and has a high vacuum.

The two tubes with parallel rows of tubes have 15#O-Ring interface on both the left and right ends, no need to apply vacuum grease, and the airtight performance is good. It is used with the flanged cold trap of the product No. LH-935781. The outer end of the section door with 14# and 24# can be used with the reaction bottle and reaction tube. The spool handle has a black mark that distinguishes the vents for easy identification when switching gases. The door spool is a high-vacuum hollow core door with a glass sphere.
