It’s a great little sampler!
The GLS Sampler is designed for general purpose or priority pollutant sampling in municipal and industrial applications where a full-size sampler is too large. It collects composite samples, based on time or flow intervals, in 1- or 2.5-gallon glass or polyethylene bottles, or in 2-gallon disposable ProPak bags.
With GLS’s simplified programming, setup takes less than a minute. In the field, the operator simply calls up the program with two keystrokes, presses the “go” button – and the sampling routine begins. You can also key in an alternate program in the field, without losing your stored program.

STANDARD FEATURES
-
Overall diameter is only 16.5 inches (42 cm), so GLS fits easily into manholes as small as 18 inches (46 cm), and also easily drops into most offset manholes.
-
Dry weight is less than 25 lbs (12 kg), the lightest sampler in the ISCO line.
-
Hinged handle makes one-handed carrying a breeze.
APPLICATIONS
-
Wastewater effluent
-
Stormwater monitoring
-
