No-purge groundwater sampling device provides comparable, formation quality samples of ALL parameters from small-diameter (1.5" Sched 40 and larger) wells for both short and long-term monitoring.
Disposable. Fits in 1.5 Schedule 40 and larger wells. Standard material = virgin 4 mil PE. Tensile strength 25-35 lb.
Absolute maximum volume obtainable without spilling 600 mls
Fill stroke is the length of the sampler when used in 1.5-inch to 2-inch wells. It will be longer for larger diameter wells. Alternative method of recovery is recommended for use in larger wells - see link below.
