Labcon Culture Tubes Plastic with Dual-Position Caps Polystyrene Culture Tubes. Many blood banks and inoculation sites require a particular type of cap with a very specific type and/or size of opening and these Labcon Polystyrene Culture Tubes with Dual-Position Caps are one of the best products for inoculation of any kind. These tubes contain approximately one million cells when compared to a cotton swab or loop filled with cotton swabs and the caps are positioned so that they will not roll off of the edge of the culture dish. The flexible dual-position cap is easy to remove for sampling and also enables convenient pouring of the culture without having to open and manipulate the base. Large openings in the necks of the tubes allow for easy volume adjustment and the caps once on provide a leakproof unit. The tubes are constructed of polystyrene and are translucent. They have an ovoid shape and are designed for vertical inoculation. Flat-bottom tubes have two large see-through drainage eyes at the base of the tube. The larger opening also accepts a cotton swab or filter. Nonsterile tubes have a plain non-diaper stopper (sold separately).
