Intended for shallow or deep waters, these bottles are called “horizontal” because they descend, parallel to the bottom. They are pulled sideways just before closing by the operator. This ensures a representative water sample for that specific depth. They are ideal for sampling at the thermocline, at other stratification levels, or just above the bottom sediments. These popular and versatile bottles come in your choice of transparent acrylic or opaque PVC. PVC is more durable and less costly, but the acrylic allows you to view the bottle contents immediately.
When running metal, organic, or any other chemical analyses, it is best to run a blank on the sampler prior to use.
Alpha samplers are not suitable for chemical analysis of contents due to the potential for contamination (i.e. by mercury and phosphorus) by the materials in the sampler’s construction. For chemical analysis, choose our Beta or suggested Kemmerer water samplers.
Beta bottles are 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. A thermometer can be mounted inside acrylic bottles.
NOTE: Volume may vary slightly. It is recommended that you verify the exact volume of your bottle prior to use.
