Alpha Bottle Kit - 2.2L Vertical, PVCIncl line, messenger, carry case

About Alpha™ bottles Alpha™ Van Dorn-style bottles have flexible, plunger-like blue polyurethane end seals for reliable sealing. Black latex tubing is used to close the bottle because it better resists decay in sunlight and in water than amber tubing. It is an extremely strong elastic material but may leach a small amount of heavy metals or other contaminants. The end seals may leach trace amounts of mercury into the water sample in the range of  20 - 450 ng/L (nanograms per liter). End seals may also leach phosphorus in small amounts.  When tripped by a messenger, the urethane end seals snap tightly onto each end of the cylinder, producing an almost leakproof seal. A small amount of sample is always lost until a slight vacuum forms inside as the sealed sampler is lifted.  Alpha™ bottles feature a stainless steel trip head for durability and high performance. Nylon safety line connects the end seals to hold them in place even if the latex tubing breaks.
