Larger bottles are good for collecting small plankton. The wide-open mouth collects a true water sample with no contamination from other water levels. Water flow is not restricted during descent - desirable for collecting plankton, floating sediments and for metallic ion avoidance. Your choice of transparent acrylic or more durable opaque PVC.
Designed for trace metal sampling. Also may be used for organic sampling to concentrations of mg/L. When running metal, organic, or any other chemical analyses, it is best to run a blank on the sampler prior to use.
This bottle is excellent for near off-shore (to 200 m) trace metal sampling, since there are no metal parts to touch your sample. You avoid the metallic ion contamination that can cause major errors in algal assays or productivity. Beta Van Dorn bottles have rigid, white plastic end seals for clean sealing. The bottle ends are machined to fit foam silicone gaskets. Amber latex tubing, which does not leach measurable amounts of metal, closes the bottle. Beta™ bottles feature a nylon safety line connecting the end seals, so if the closing tube breaks, you’re less likely to lose your expensive seals. This is why Beta bottles have an excellent track record in a wide variety of field conditions.
This sampler requires a messenger and line (included in kits) for operation. It is not suitable for series sampling. A thermometer can be mounted inside acrylic Beta bottles.
