ABSTRACT:
An ultra-pure chemical sampling apparatus has an elongated sampling tube which is lowered into the liquid to obtain samples of the chemical. The sampling tube extends the depth of the liquid and holes arranged along the tube provides for a representative sample to be obtained at different depths. The sampling tube is coupled to a collection bottle by a tubing of which a section of flexible tubing is coupled to a peristaltic pump to pump the liquid up the sampling tube, through the tubing and into the collection bottle. A cap is used to seal the sampling tube and a secondary containment receptacle is used to enclose the bottle in order to inhibit the escape of chemical fumes which could harm the environment or the person obtaining the sample.
