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.
