适用于I型和II型地下抓斗式取样器，硼硅玻璃制造 Each sampler consists of an inert polypropylene head with stainless steel fittings and an aluminum pole assembly with a golden alodine finish. It comes with a 1000 mL narrow-mouth sample bottle with a PTFE- lined cap. To use it, screw a sample bottle into the head and lower to the desired depth. Pull the cable at the top of the handle which will lift a spring-loaded plunger from the bottle opening, allowing liquid to enter through four 5/8" diameter holes. Release the cable when the bottle is full to reseat the plunger.
