The PVC body is opaque, but is more durable and less expensive than acrylic. 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, inquire about the Beta or suggested Kemmerer water samplers. This sampler requires a messenger and line (not included, except in kits) for operation. A thermometer can be mounted inside acrylic Alpha™ bottles.
