No it does not. ESP ran the most extensive spike test available, under method 8260B and 8270, and the results on our PVC where equal to polyethylene, in all areas recognized.

PVC naturally sinks due to specific gravity in water, but ClearView™ sink as well if not better than any single weighted bailer on the market. In addition, ESP’s ClearView™ bailers have no weights, to block the flow of the sample being taken or the purging of the bailer, which results in quicker sampling and purging time.

ESP manufactures a .46″ and .70″ bailer in three and four foot lengths. Our micro bailers are made of the highest quality medical grade PVC. This allows the bailers to maintain its shape, deterring the bailer from bending and hanging up in the well. In addition, Geoprobe has tested ESP micro bailers and stated, “the micro bailers work great and retrieved full samples without hanging up.”

This is a great question, but you will not have to worry about that anymore. Recently, we changed our mold for the balls, and there is no longer an issue with the ball sticking.

First of all, our locking I.D. plug truly locks the well; we challenge anyone to prove otherwise. In addition, our plug is manufactured out of a glass-reinforced polymer for additional strength. We incorporated a large wing nut design for ease of installation and removal. The plug is water tight, florescent orange, which helps locate the well, and are priced to you save money.

Yes we do. We have ClearView™ Bailers in 1.5” x 4′ and 7′ sizes. Also we have 3.33″ x 3′ that holds up to 5100 mL.

Yes, ESP offers a hydrocarbon recovery bailer. We use a polyethylene ball, which floats in water, but sinks in hydrocarbons, which means when you lower the bailer in the well and capture both water and hydrocarbons, the bailer will release the water, but will capture hydrocarbons to be removed.
