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.
Alpha samplers are not suitable for trace metal analysis due to the potential for contamination (i.e. mercury and phosphorus) by the materials in the sampler’s end seals. For trace metal analysis, choose our Beta Bottle water samplers.
A thermometer can be mounted inside acrylic Alpha™ bottles.
