Nasco Whirl-Pak® Write-On Sterile Sample Bags have a convenient white Write-On Strip that will accept virtually any writing instruments (ballpoint pen, pencil, or felt-tip marker) for easy sample identification. Bags are made of high-quality blended polyethylene. Leakproof closure (whirling or tightly folding the tab over 3 times) prevents impurities from entering the bag and contaminating the sample. Bags are sterilized using ethylene oxide gas at an independent ISO-certified facility. FDA approved. Capacity is measured in fluid ounces. Volume and dimensions are approximate.

Photo of Nasco Grease Trap Sampler

The Nasco Grease Trap Sampler is designed with an inside diameter of 1.38" to allow for the passage of large solid particles during sampling of grease (liquid grease and oils) holding tanks. It will not work with solid or semi-hardened materials. Unit is lowered into the liquid, the float valve opens allowing the sample to flow in. Upon reaching the bottom, the unit is raised up and the valve closes holding the sample inside. Clear tubing is marked at 1-Ft intervals. Made of two 4-Ft sections that screw together.

The Sludge Judge® is designed to take accurate readings of settleable solids, 5% or less, in a variety of liquids, to any depth. It is ideal for sewage treatment plants, chemical plants, and food processing facilities - anywhere that accurate sample levels of settleable solids in noncaustic materials are needed. The unit holds approximately 3 oz. per foot (89 ml per 0.31 m). The Sludge Judge® shippes in 3 five foot sections of ¾" plastic pipe with screw type fittings. The top section includes a nylon rope for raising and lowering the sampler.

For maximum strength and rigidity - use the Sludge Judge® Ultra! Designed for sampling 5% or less solids. It is constructed of extremely strong polycarbonate that is treated with an ultraviolet stabilizer to help reduce deterioration from the sun’s harmful rays. The material is very rigid, minimizing bending of the unit when it is full of water or other liquids. Durable in cold temperatures and it can withstand heat up to 280° F (138° C) with careful handling. The 3/4" (1.9 cm) diameter tubing is marked with blue tape to designate 1-ft. (.31 m) measurements on the tubing.

The Sludge Judge® II is made from a 1-1/4" (3.18 cm) outside diameter plastic tubing resulting in double the capacity and a very rigid unit when assembled. Designed for sampling 5% or less solids. It holds 6 oz. per foot (178 ml per .31 m) and can be assembled according to the requirements of the job. Add or subtract sections as needed, and the 1-ft. (.31 m) markers on the tubing will help identify the amount of sludge in the tank. The unit is made up of three 5-ft. (1.53 m) sections (top, extension, bottom) or individual sections can be combined as required.

If you need to collect a sample from a horizontal flowing stream, such as a sewer, the Nasco Swing Sampler is just what you need. The end of the sampler swings, allowing collection from different angles, including 90°. The 6-Ft fiberglass pole extends to 12 ft and the 8-Ft pole extends to 24 ft. Unit comes with a 960 mL polyethylene bottle with vinyl lined leak-proof cap.

The Nasco B01098WA Coliwasa Composite Liquid Waste Sampler permits representative sampling of multiphase wastes for a wide range of viscosity, corrosivity, volatility, and solids content. This unit can be used to sample most containerized liquid wastes, except those containing ketones, nitrobenzene, dimethylformamide, mesityl oxide, and tetrahydrofuran. Its simple design is easy to use, and allows the rapid collection of samples, minimizing the exposure of the sample collector to potential hazards from the wastes.

The Nasco B01477WA Fuel Sampler is designed for sampling ethanol and ethanol-blended fuels. The Nasco Fuel Sampler is efficient and easy to use. It is made up of three 5 ft. (1.53 m) sections of clear PVC that screw together to make a 15 ft. (4.60 m) length. As the sampler is lowered into the fuel tank, the float valve at the bottom opens, allowing the fuel up into the tube. When the bottom of the tank is reached, simply raise the sampler up to close the valve and hold the sample inside, showing a core section of the fuel.
