Vertical Point Water Sampler
|
 |
| Water Sampler Units Include: -sample cylinder: standard volumes: 2.0, 5.0, and 8.0 liters; clear polycarbonate (92 mm I.D., 3 mm wall thickness) or PVC (95 mm I.D., 10 mm wall thickness) with UHMW end bushings; stainless steel tube weight (1.5 kg) -armored thermometer (optional): mounted inside clear polycarbonate water samplers; available in C or F -PVC drain and vent: 20 mm diameter; latex drain tube and pinch clamp -internal closure: latex tubing (12.5 mm I.D.; 19.5 mm O.D.) with internal elastic "back-up" cord; Teflon coated stainless steel spring with Kevlar lanyards available at an additional cost -solid rubber ball end seals: internal closure and arming cables are attached by threaded PVC fittings; all components easily serviced -vertical release mechanism: Polyethylene and stainless steel construction; simple, spring loaded anvil-release pin provides easy sampler loading; built-in heavy duty handle; stainless steel cable clamps allow easy attachment of multiple samplers to a single wire (maximum diameter: 9 mm) for "in-series" deployments -messenger: 333 gm cast bronze with stainless steel hardware, split messenger with hole for lanyard attachment |

  *Thin-layer sampling of physical (temperature), chemical (dissolved gasses, nutrients, metals) and biological (phyto-bacterioplankton) data *Non-metalic sample containment *Messenger activated horizontal release mechanism is easy to load; near bottom water recovery with bottom tripping assembly (optional) |
|
| -horizontal release mechanism: Polyethylene and stainless steel construction; simple, spring loaded release pins provides easy sampler loading and sure-fire operation; built-in heavy duty handle; single sampler attached to end of line |

VERTICAL POINT WATER SAMPLERS, PVC CONSTRUCTION |
||||
|
PVC DISCRETE POINT WATER SAMPLERS: Horizontal or vertical
orientation, opaque PVC and polyethylene construction, silicone end seals, heavy
duty amber latex internal closure, stainless steel lanyards,
simple-single-moving-part release mechanism, solid bronze messenger (300 gm), 20
m calibrated line (0.5 m increments), linereel, padded toolbox carry case, 2.2
liter capacity, complete, $255
Notes: Designed for general limnological uses and light sensitive studies of phytoplankton and bacterioplankton. In-series sampling possible with vertical models and optional bronze split-messengers. Horizontal models useful for thin layer or near bottom sampling. Heavy-duty latex internal closure is easily tightened or replaced with a simple, “thread-on” assembly. |
POLYCARBONATE POINT WATER SAMPLERS |

|
Horizontal or
vertical orientation, clear polycarbonate and polyethylene construction,
ultra-clean silicone end seals, heavy duty amber latex internal closure,
stainless steel lanyards, simple-single-moving-part release mechanism,
solid bronze messenger (300 gm), 20 m calibrated line (0.5 m increments),
linereel, padded toolbox carry case, 2.2 liter capacity, complete, $285
Notes: Designed for general limnological use where sampler clarity is important (zooplankton collection, near bottom water recovery w/o contamination, hydrogen sulfide…). EPA approved for ultra-clean analysis of water. In-series sampling possible with vertical models and optional bronze split-messengers. Horizontal models useful for thin layer or near bottom sampling. Horizontal samplers can be inverted and actuated with a sharp tug on towline with a “Toggle-Release” (above right, included). This is very useful when deploying a sampler from a bridge where currents deflect the towline and the messenger can not effectively hit the release mechanism. Heavy-duty latex internal closure is easily tightened or replaced with a simple “thread-on” assembly. |
