PVC constructionPVC DISCRETE POINT WATER SAMPLERS

  • Horizontal or vertical orientation
  • opaque PVC and polyethylene construction
  • silicone end seals
  • heavy duty amber latex internal closure
  • vertical point samplerstainless 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 $310
  • Other sampler volumes available (complete, as above):
    • 3.0 liter ($350)
    • 5.0 liter ($400)
    • and 10 liter ($500)
  • Internally mounted thermometers with armored case (centigrade, 5 to 45 degrees, liquid spirt filled): $60.

Notes: Designed for general limnological uses and light sensitive studies of phytoplankton and bacterioplankton. Inseries 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, “threadon” assembly.


POLYCARBONATE POINT WATER SAMPLERS

  • water samplers Horizontal or vertical orientation
  • clear polycarbonate and polyethylene construction
  • ultraclean silicone end seals
  • heavy-duty amber latex internal closure
  • stainless steel lanyards
  • water samplerssimple 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 $310
  • Internally mounted thermometers with armored case (centigrade, 5 to 45 degrees, liquid spirt filled): $60.
  • Other sampler volumes available (complete, as above): 3.0 liter ($350), 5.0 liter ($425).

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 ultraclean analysis of water. Inseries 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.

 


Optional Equipment

  • Extra Line and line reels ($39 / 20 meter section)
  • Directional Fin for horizontal water samplers in flowing waters ($75)
  • Bottom Tripping Mechanism with pad for automatic actuation near mud-water interface ($145)
  • Internal Mounted Thermometers ($65) (-5 to 50 degrees centigrade liquid spirit filled, armored case, mounted in inside of clear samplers only)
  • Pull-type Closing Assembly for deploying sampler off bridge without use of messenger. Sharp tug on line actuates close of sampler ($55)
