Tubing

Polyethylene Tubing MP1 Pump: 12 x 16 mm, roll of 50 m 12 x 16 mm, roll of 100 m

Groundwater sampling demands the highest standards in tubing quality because the contamination potential is significant. Tubing quality is even more important when using with a dedicated pump as your sample quality will depend on robust, leak tight connections for the duration of the sampling period. Van Walt’s specialist tubing is hallmarked and carries our QA plus stamp of purity and cleanliness. It is available in a variety of sizes and roll lengths and is ideal for sampling for trace metal; Hydro-carbons; Volatiles and Macro-parameters analysis. All our tubing is hydro-carbon resistant to protect your samples’ integrity while making system installation and operation easier and more economical.

Foot Valves and Dyneema

Our Foot Valves come in a variety of sizes and can make very powerful pumping systems capable of sampling to great depths. These pumps, using no electrical components are useful if you have to sample in an intrinsically safe way. Stainless steel foot valves are re-usable as they can be cleaned in a dishwasher making them more cost effective than plastic valves which cannot be effectively cleaned, so could cause sample contamination if re-used. Our Dyneema rope is the material of choice when it comes to deploying level loggers. It is strong, light weight, floats in water, water resistant, chemically inert, non-stretch and highly durable.
