Whirl-Pak B01356 Bottom Section with Valve - 5 ft. (1.53 m)

The Whirl-Pak B01356 is a replacement bottom section for the Sludge Judge® II sampler, designed to collect sludge and sediment from the bottom of tanks, clarifiers, and wastewater basins. It allows operators to measure sludge blanket depth and analyze settleable solids accurately.

This bottom section includes a valve at the base that seals the sample during retrieval, preventing loss of material while lifting the sampler. This helps maintain clear layer separation and accurate depth readings during wastewater or process sampling.

The B01356 is a 5-ft (1.53 m) section with approximately 1-1/4 in. diameter tubing and a capacity around 890 mL, allowing sufficient sample volume for sludge evaluation and visual measurement.

Yes, the unit is part of a modular Sludge Judge system, where top, extension, and bottom sections can be combined to reach deeper tanks. The quick-connect design allows users to customize sampling length based on application needs.

This component is widely used in wastewater treatment plants, settling basins, lagoons, industrial clarifiers, and water treatment systems to monitor sludge levels and process performance. Sludge Judge tools are designed to measure settleable solids in liquids, especially at low solids concentrations.
