WaterMark Dome-End 36” Disposable Polyethylene Single Check Valve Bailers, 1/2” O.D., Case of 24

1/2” O.D. with 500 ml capacity and 5/16” Delrin Ball, Case of 24. Made of inert polyethylene, these inexpensive, disposable bailers are pre-cleaned in Liquinox™ laboratory detergent and then rinsed with de-ionized water, helping you eliminate cross contamination of samples and time-consuming clean-up in the field. Each bailer measures 36” long and has a friction fit nozzle for easy removal of sample. Has polyethylene retainer to retain the ball when emptying the bailer from the top. Also has a slide-in slotted nozzle for easy sample removal. Domed-designed ends avoid hang-ups when lowering or retrieving bailers.
