Designed for surface sampling and effective in hard-to-reach areas, the 8 in. inch (20.3 cm) long probe consists of a polypropylene holder with detachable handle that is adhered to a durable polyurethane sponge that resists tearing and fraying. Probe is packaged in a sealed 24-oz. (710 ml) write-on bag and hydrated with 10 ml of HiCap™ Neutralizing Broth. Product is terminally gamma processed to guarantee sterility. Box contains five foil pouches with 20 probes each for a total of 100 probes. Bags are 9 in. L x 6 in. W (23 x 15 cm) with a thickness of 2.5 mils (.064 mm). To use, tear open the top of the bag; squeeze out any excess neutralizing broth; swab the surface; insert the sponge back into the bag; and, while holding the sponge from the outside, unscrew the handle and discard. Drop the sponge into the bag, fold the top of the bag over three or more times, bend in the wire tabs to close, and send to a lab for testing.

Shelf Life from Sterilization date found on the Sterility Documentation: 2 years from Sterilized date found on your Sterility Confirmation due to the buffer

Two-year shelf-life with ambient storage at 36°-86° F (2°-30° C). The bags are packaged in a foil liner bag to prevent evaporation of the buffer.

Do NOT use for sampling ethanol or ethanol blended fuel. 

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® comes in 5 ft. (1.53 m) sections of 3/4 in. (1.90 cm) plastic pipe with screw-type connectors. The top section includes a nylon rope for raising and lowering the sampler. Individual sections can be combined as required to achieve the length needed. Do not use in liquids over 165° F (74° C). Sludge Judge® is not autoclavable. A convenient cotton canvas carrying case that holds four sections, a cleaning brush, cleaning rod, and cotton strips are available.

To use:

1. Slowly lower the Sludge Judge® to the bottom of the tank. The float valve opens (see figure A), allowing materials to flow in. When the bottom has been reached and the pipe has filled to the surface level, tug slightly on the rope as the unit is raised. This sets the check valve(see figure B), trapping the mixture inside.

2. When the unit has been raised clear of the liquid, the amount of solids in the sample can be read using the 1 ft. (0.31 m) increments marked on the pipe sections. To release the material in the unit, touch the pin extending from the bottom section against a hard surface. This opens the check valve to drain the sample. One-year warranty.

Blended, Virgin Polyethylene Film: exceptional clarity, superior strength, sterilized after manufacturing, FDA approved for food contact.

• Puncture-Proof Closure Tabs: inner and outer tapes for longevity and stability, wire for easy opening, pouring, and closing.
• Post-Manufacturing Sterilization: increased sample integrity, perforated closure to maintain sterility. Opening Pull tabs: for easy opening, non-slip textured Tyvek.
• Continuous Perimeter Seal: maximum protection against leaks.
• Trusted, Puncture-Proof Closure Tabs: tape extends beyond wire to eliminate sharp ends and provide a sturdy grip, wire tabs hold the top open for easy access to add to or remove sample, worry-free, no-leak closure for sample integrity.

Bags should not be used at temperatures above 180° F (82° C). Bags can be frozen to any temperature, even liquid nitrogen temperatures down to -346° F (-210° C) —careful handling is required after freezing. Capacity is measured when the bag is closed and tab is folded over three times. Volume and dimensions are approximate.

Dimensions:

• 4 oz. (118 ml), 3” W x 7-1/4” L (7 x 19 cm)
• Film Thickness: 3 mils (.076 mils).
• Box of 500.

Rack Size: 10 in. x 10 in. x 3-1/2 in. (25.4 x 25.4 x 9 cm)

Compartment Size: 3 in. x 2-3/8 in. (7.6 x 6 cm)

Made in the U.S.A. of 10 and 12-gauge steel fused together to create strong joints and straight lines. Rack is finished with an electrostatically applied powder coating. The result is a strong, durable finish which will stand up to many laboratory materials and the rack can be autoclaved. Max dry temperature is 300°F (148°C) and wet temperature is 500°F (260°C). Dimensions listed above are approximate.
