Based on a 1927 design by Dr. George Kemmerer, University of Wisconsin, the Kemmerer bottle has long been favored by limnologists and shery biologists. With few moving parts and a simple trip, it offers trouble-free operation.

This series of versatile bottles are sized from 0.4 to 6.2 liters. All are constructed with corrosion-resistant stainless steel. Seals are made of silicone which is a better alternative to polyurethane in that silicone does not leach metal contaminants. Metal parts are 316 or 304 stainless steel except for fasteners and plastic-coated cables of 18-8 steel.

When running metal or any other chemical analysis, it is best to run a blank on the sampler prior to use.

Using Kemmerer Samplers
1. All-Angle trip heads lock the seals open before lowering into the water. In the open position, water flows smoothly around the bottom seal and into the cylinder, thereby obtaining an accurate and representative water sample to the milligram per liter (mg/L) level.
2. Lower the bottle on a line to the desired depth.
3. Drop a messenger down the line
4. Shaft retainer opens and top seal falls, closing both ends
