Collection broths play a critical role in the success of an environmental monitoring program. HiCap™ (High Capacity) Neutralizing Broth is the first collection broth developed specifically for use in the food and beverage industry. By neutralizing residual sanitizers on the sampled surface and maintaining the viability of the collected microorganisms for up to 72 hours, HiCap™ helps prevent false negative test results and facilitates accurate quantification of microorganisms.

Medical-grade polyurethane sponge provides improved rigidity making it easier to handle and manipulate than a cellulose sponge. It also resists tearing and fraying, allowing for vigorous scrubbing on irregular surfaces to disrupt biofilm.

Microorganism Viability

Microorganism Viability

To ensure the accuracy of pathogen detection and quantitative test results it is important to maintain the viability of the collected organisms until the sample is processed by the laboratory, typically 1-2 days.

HiCap™ was formulated to recover and maintain both gram-negative and gram-positive organisms.

POLYSPONGE™ HYDRATED

POLYPROBE™ HYDRATED

Durable high-density polyurethane sponge is packed in a sealed 18-oz. (532 ml) write-on Whirl-Pak® bag and hydrated with 16 ml of HiCap™ Neutralizing Broth.

Box contains five foil pouches with 20 sponges each for a total of 100 units. Bags are 9" L x 4" W (23 x 11.5 cm) with a thickness of 2.5 mils (.064 mm).

Two-year shelf-life with ambient storage at 36°-86° F (2°-30°).
PolySponge™ - B01590WA
PolySponge™ with Glove - B01591WA

NOTE: To use the glove, tear off the glove pack along the perforation. The glove is folded with the wrist opening extended so that is can be extracted from the pouch and fitted without touching the hand and finger areas.

Ideal for collecting environmental surface samples without touching the sponge. The bendable polypropylene handle allows maximum contact of the sponge with the sampling surface and also helps with the collection of hard-to-reach surfaces, around corners, and irregular shaped areas. The innovative twist-off head holds the polyurethane sponge securely but is quick and easy to remove from the handle once sample collection is completed.

The PolyProbe™ is sealed in a 24 oz. (710 ml) write-on Whirl-Pak® bag and hydrated with 10 ml of HiCap™ Neutralizing Broth. Bags are 9" L x 6" W (23 x 15 cm) with a thickness of 2.5 mils (.064 mm).

Two-year shelf-life with ambient storage at 36°-86° F (2°-30° C).

Potential Benefits of

POLYURETHANE SPONGES for ENVIRONMENTAL Surface Sampling

  1. Non-Toxic: Polyurethane sponges being used by Whirl-Pak® are non-toxic and do not contain biocides. Unlike the “wet” cellulose manufacturing process, there is no need to include biocides to control microbial growth during the polymerization process to produce polyurethane sponges.
  2. Routinely Used in Medical Devices: Unlike cellulose sponges, polyurethane sponges have a long history of use in medical products that are in contact with the body (e.g. wound dressing) or inside of the body (e.g. wound drainage) because of their non-toxic properties and other attributes such as tensile strength.
  3. Batch to Batch Consistency: The polyurethane sponges utilized by Whirl-Pak® are manufactured using high purity raw materials and well-controlled manufacturing processes. Consequently, the chemical and mechanical properties of the polyurethane sponges are consistent from batch to batch.
  4. Strong; High Tensile Strength: These polyurethane sponges are less susceptible to flaking and tearing when sampling an irregular and abrasive surface. Therefore, rigorous scrubbing of a rough surface can be done with minimal to no sponge fragmentation.
  5. Good Water Absorbency and Retention: The polyurethane sponges that Whirl-Pak® uses release liquid only under pressure. Consequently, the amount of liquid applied to a surface during sampling is comparable between cellulose and polyurethane sponges.
