These lightweight bags are made of five layers of different materials bonded to form one 0.14 mm (5.5 mil), flexible, leakproof, impermeable material. The materials are inert and will not react with or absorb gas.
These collection bags have a large 35 mm (1-3/8 in) ID molded opening with ‘O’ rings for a slip sealing fit over standard 35 mm (1-3/8) male fittings. For volume calibration syringes, see page F38. On one side of this opening is a female Luer lock port and on the opposite side is a hose barb. Both can be used for sampling or injection. The female Luer port is connected to an internal 1.6 mm (1/16 in) bore tubing looped inside the bag for mixing and sampling. Mounted on the lower portion of the bag is a self sealing septum for syringe withdrawal or injection. The opposite side has an on/off valve with a hose connection. These bags are available in 6 sizes and are supplied non-sterile. Their functional volumes are listed below, and they have little back pressure. These bags are typically used with a stopcock, having one port measuring 35 mm (1-3/8 in) OD.
