ISCO 3710 Portable Composite Sampler

  • Quick and Easy Set Up Up to 24 sampling stop and resume times can be preset for unattended automatic sampling
  • Thick Foam Insulation and 20lb Ice Capacity Allows optimum effectivness for cooling and preservation of samples
Product Options


The 3710 Automatic Sampler is simple to operate and has high volume capacity for single - bottle sampling. Composite samples can be collected either at flow or time based intervals.

Auotmatic samples can be collected in either a 2.5 gallon glass or polyethylene bottle, or a 4 gallon polyethylene bottle. Up to 24 sampling stop and resume times can be preset for unattended, automatic sampling.

Set up and programming of the automatic sampler is easily done. All the user has to do is choose the options needed from the selections displayed on the two-line, backlit LCD.

The ISCO 3710 automatic sampler has a thermal resistance of R-11 which allows maximum effectiveness for cooling samples. The base of the sampler is insulated by one inch thick foam, keeping the unit more rigid and less affected by ambient temperatures.

Standard Features

  • Fail-safe float shutoff prevents overfilling of sample bottle
  • Exclusive LD90 Liquid Presence Detector and pump revolution counting system ensure accurate, repeatable sample volumes.
  • Thick foam insulation (R-11) and 20-lb ice capacity (with 4-gallon bottle) to preserve samples.
  • Quick, easy setup for:
    - Uniform time intervals
    - Non-uniform time intervals
    - Flow-paced sampling with or without time delay
  • 3710 Controller is housed in a NEMA 4X and 6 (IP67) environmentally sealed enclosure, and is fully interchangeable between portable and refrigerated samplers.
