This valved liquid sampler prevents contamination and is easy to operate. Ultra-pure PTFE/FEP construction is suitable for harsh or critical chemicals, while economical polypropylene (PP) works for aqueous solutions and noncorrosive chemicals. Both material options feature a smooth surface where no crevices or pores exist, eliminating concern for accumulation and cross-contamination. Integral scraping ring can be used to mark depth, or to wipe excess sample off the outside of the tube.

Push-button valve is normally closed. Simply push the button to open the valve and let the sample into the tube. Sampler features threaded connections that are easy to disassemble and clean.
