Isco GLS Portable Sampler

Isco GLS Compact Composite Sampler

  • Easy to handle
  • One-button Programming
  • Accurate, repeatable sample delivery
  • Ultra compact

ISCO’s GLS is a composite sampler which allows readings to be taken at time or flow based intervals. Samples can be collected in either 1 or 2.5 gallon glass or polyethylene bottles or if required a 2 gallon disposable ProPak bag. The GLS portable sampler has a very simple programming system with setup able to take less than a minute, allowing the field operator to start sampling with the touch of two buttons on the unit. Pressing the go button starts the sampling routine. The auto-sampler can be programmed to an alternative set up, without losing the original program setup.

It’s a Great Little Sampler!
The GLS Sampler is designed to collect composite samples for general purpose monitoring. It holds a 1- or 2.5-gallon sample bottle, or a 2-gallon disposable ProPak® bag.

One-button Programming
With GLS’s simplified controls, operation is quick and easy. Just select answers to six short questions, then store the results as the default program.
Once in the field, the operator simply calls up the default program with two keystrokes, presses the green “GO” button – and the desired sampling routine begins

Ultra compact
Overall diameter is only 16.5 inches (41.9 cm), so the GLS fits easily into manholes as small as 18 inches (45.7 cm), and also easily drops into most offset manholes.

Easy to handle
With a dry weight of less than 25 lbs (12 kg), GLS is the lightest sampler in the Isco line. A hinged handle makes one-handed carrying a breeze.

Accurate, repeatable sample delivery
The patented* LD90 Liquid Presence Detector and Isco pump revolution counting system delivers accurate, repeatable sample volumes time after time.
