About Beta bottles

Beta™ Van Dorn-style bottles have rigid, white ASA plastic end seals with silicone gaskets. Amber latex tubing is used to close the bottle because it leaches fewer contaminants than the black latex tubing used on our Alpha™ bottles. It is not as durable, however. The Beta™ sampler is excellent for trace metal sampling, as there are no metal parts to touch your sampler.

When tripped by a messenger, their ASA plastic 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 out of the water.

As with our Alpha™ bottles and Ekman grabs, Beta™ bottles feature a 316 stainless steel trip head mechanism for durability and high performance. They also feature a nylon safety line connecting the end seals, so if the latex tubing breaks, the end seals often remain with the bottle.

Choose between completely transparent acrylic or the more durable, less costly opaque PVC main tubes. Acrylic allows full view of the contents during your field work.

Warning: These seals close with considerable force and could cause injury. Do not operate out of the water!
