Omnifit(R) GL38 Gallon Bottle Cap with Luer Port, 2 Ports, Filter & Check Valve Included, OMJ4312F, 1 Piece

The thread standard for the amber gallon bottle with handle is GL38, and it can be used with most reagent bottles and burettes (thread standards 38-400, 38-410, 38-415, 38-430) sold in Japan. This is a gallon bottle cap with a thread standard of GL38 that connects by passing a 1/8" outer diameter fluororesin tube through 2 to 4 female lure ports on the top of the white body. The female lure port can also accommodate separately sold lure port accessories or the male lure part of various commercially available syringes. The port spacing is 11mm for the 2 port type, 9mm for the 3 port type, and 6mm for the 4 port type. There are types with and without a PTFE 10um inlet filter in the center of the body top to prevent the inhalation of contaminants and a Viton check valve on the inside to balance the negative pressure inside the bottle. The blue cap is made of polypropylene (PP) and the white body that comes into contact with the liquid is made of PTFE. The cap can be rotated freely while preventing the tube already connected to the port from twisting when attaching or detaching the cap. Number of ports: 2 Filter & check valve: 1
