Labplas Sani-Sponge pre-moistened kits are sterile, ready-to-use surface sampling sponges for environmental monitoring and sanitation verification. Each kit has a biocide-free cellulose or polyurethane sponge already moistened with transport medium, inside a 7.5 × 11.5 in TWIRL'EM sampling bag with a writing area and a twist-wire closure. Open, swab, return the sponge to the bag and seal it, with no hydration step.
This page covers four transport media: Buffered Peptone Water (BPW), Dey-Engley Neutralizing Broth (DE), Letheen Broth (LT) and Neutralizing Buffer (NE). Each broth is available with a cellulose sponge, with or without a pair of sterile gloves, or with a polyurethane sponge (without gloves). All are packed 100 per case. They're used in food and beverage QA/QC, food processing plants, environmental labs and research laboratories. Labplas Sani-Sponge kits are available in Canada from Cambridge Environmental Products with CAD pricing and Canadian purchasing support.
The sponge comes moistened with transport medium. Your team doesn't have to prepare and dispense broth, and every sample starts the same way.
Sanitizer residue picked up by the sponge can keep killing organisms on the way to the lab, which can give false negatives. DE, LT and NE are neutralizing media, which Labplas includes to neutralize biocides from sampled surfaces. BPW is non-neutralizing.
Cellulose (yellow) has many small pores and suits smooth surfaces such as stainless steel. Polyurethane (white) is a stiffer, hydrophilic foam that releases liquid more easily, and suits rougher surfaces such as textured belts, floors and drains.
The "with gloves" kits include a pair of sterile blue polyethylene gloves. Labplas packs them in individual pairs, irradiates them and folds them to keep them sterile while you put them on.
Labplas sterilizes Sani-Sponge kits by irradiation, with a sterility assurance level (SAL) of 10⁻³ established according to ISO 11137. The kits are also listed as DNase-free, RNase-free and non-pyrogenic (endotoxin limit 2.15 EU/device). The sponge is free from biocides, so it won't kill organisms in the sample before testing.
The sponge comes inside a TWIRL'EM sampling bag with a writing area. After sampling, the sponge goes back in the bag, and you twirl the bag by its 2 round wires and fold them over to seal it. The same bag goes to the lab, and Labplas lists the bags as compatible with incubators and homogenizers (stomachers).
Labplas states the bag materials meet FDA 21 CFR 177.1520 and EU Regulation No 10/2011 for food contact. Labplas also notes the kits can be used as part of a CFIA Preventive Control Plan (PCP) and HACCP program. That is not a CFIA approval of the product itself.

| Broth | Cellulose | Cellulose + Gloves | Polyurethane | Case |
|---|---|---|---|---|
| Buffered Peptone Water (BPW) | KSS-67110-BPW | KSS-67115-BPW | KSS-67810-BPW | 100 (5 × 20) |
| Dey-Engley Neutralizing Broth (DE) | KSS-67110-DE | KSS-67115-DE | KSS-67810-DE | 100 (5 × 20) |
| Letheen Broth (LT) | KSS-67110-LT | KSS-67115-LT | KSS-67810-LT | 100 (5 × 20) |
| Neutralizing Buffer (NE) | KSS-67110-NE | KSS-67115-NE | KSS-67810-NE | 100 (5 × 20) |
The data sheets give the following for each medium:
| Broth | Type | pH | Shelf Life | Storage |
|---|---|---|---|---|
| BPW – Buffered Peptone Water | Non-neutralizing | 7.2 ± 0.2 | 24 months | 2–8 °C |
| DE – Dey-Engley Neutralizing Broth | Neutralizing | 7.6 ± 0.2 | 15 months | 2–8 °C |
| LT – Letheen Broth | Neutralizing | 7.0 ± 0.2 | 15 months | 2–8 °C |
| NE – Neutralizing Buffer | Neutralizing | 7.2 ± 0.2 | 24 months | 2–25 °C |
Labplas data sheets classify each medium as neutralizing or non-neutralizing but don't list which sanitizers each one neutralizes. The guidance above reflects common industry use. Always follow your lab method, and check neutralizer effectiveness against the sanitizers in your facility.

Specifications are from the Labplas technical data sheets for the KSS-67110, KSS-67115 and KSS-67810 codes. Some Labplas web listings show a 6 × 10.5 in bag for these kits; we've used the 7.5 × 11.5 in size from the data sheets. The volume of broth in each sponge isn't published. Contact Cambridge if you need it.
Sampling areas, transport temperatures and holding times come from your lab method or customer requirements, not from the kit. Follow your own procedure.

It's a sterile cellulose or polyurethane sponge already moistened with transport medium, in a sampling bag with a writing area, ready for surface swabbing without a hydration step.
Yes. Labplas sterilizes them by irradiation, with a sterility assurance level of 10⁻³ established according to ISO 11137.
Use the medium your lab method specifies. As a general guide, choose BPW for non-sanitized surfaces or where BPW is specified, and a neutralizing medium (DE, LT or NE) where sanitizer residues may be present. See the broth guide above.
Labplas says to store BPW, DE and LT kits at 2–8 °C on receipt. NE kits can be stored at 2–25 °C.
24 months for BPW and NE, and 15 months for DE and LT, per the Labplas data sheets.
A pair of sterile blue polyethylene gloves, packed in individual pairs and irradiated.
Labplas recommends cellulose for smooth surfaces. Polyurethane is stiffer, releases liquid more easily and suits rougher surfaces.
Not on this page. The polyurethane kits (KSS-67810 codes) come without gloves. Contact Cambridge and we'll check with Labplas.
