Clean, convenient sampling – 1000 mL and 2-gallon sizes

These convenient, single-use sample bags bring a new dimension of productivity to your water and wastewater sampling. Using the patented Teledyne ISCO ProPak® sample bag will reduce your sampling costs by eliminating the expense of washing and storing conventional bottles while, at the same time, eliminating worries about contamination from previous samples. For SW846 trace metals analysis, testing shows that ProPaks yielded results equivalent to glass bottles in all categories except mercury.

Teledyne ISCO’s 1000 mL ProPak sample bags work in any application where you currently use 1000 mL wedge-shaped plastic bottles. The 2-gallon ProPak bags – used as liners for a special 2.5 gallon bottle – are ideal for composite sampling.
