Kemmerer PTFE 1.2L Kit (includes line, messenger, carry case). The top-of-the-line Fluoropolymer (PTFE) Kemmerer sampler is available only from Wildlife Supply Company! Includes 1.2 L Fluoropolymer (PTFE) body with all-Fluoropolymer All-Angle™ trip heads. Especially useful when you need chemical or heat resistance, or both. For strength, the Fluoropolymer (PTFE) center rod is solid; therefore, a line cannot pass all the way through it and be knotted, as in our other Kemmerers. We solve this problem by including a special Fluoropolymer PTFE) adapter which fastens the line to the center rod top. Because the seals are also Fluoropolymer (PTFE), your water sample touches only Fluoropolymer (PTFE). Designed for trace metal and trace organic sampling. When running metal, organic, or any other chemical analysis, it is best to run a blank on the sampler prior to use.
