Overview
The 3M Hydrated-Sponge with 10 mL Letheen Broth (HS10LET) is a reliable, ready-to-use option for environmental surface sampling and microbiological monitoring. Designed to reduce handling time and minimize waste, this hydrated sponge format supports efficient sampling workflows in laboratory and field environments—without compromising sample integrity.
Why Letheen Broth matters (quat environments)
Each sponge is pre-hydrated with 10 mL Letheen Broth, a diluent formulated to neutralize quaternary ammonium compounds (quats). This makes HS10LET ideal for hygiene swabbing and environmental monitoring where disinfectant residues may interfere with organism recovery and downstream results.
Sponge + sample bag configuration (published)
HS10LET uses a durable, absorbent biocide-free cellulose sponge designed to withstand scrubbing while helping maintain organism viability. The sponge is housed in a 5" × 9" 3M Sample Bag (holds up to 30 oz / 0.89 L) with a blue top, wire tie for secure closure, and a writable white panel to document sample source, date, and time.
Organism viability / refrigerated hold time (published)
The biocide-free sponge format is described as maintaining microorganism viability for up to 48 hours under refrigeration for Salmonella and E. coli, and up to 72 hours for Listeria—supporting sample transport and scheduling discipline in high-throughput programs.
Decontamination + quality (published)
Both sponge and sample bag are gamma-irradiated for decontamination to support long shelf life and organism viability. The product is manufactured in the USA using globally sourced materials, is ISO 9001:2008 certified, and is intended strictly for laboratory use.
Benefits (published)
- Ready-to-use, pre-hydrated sponges for easy and convenient environmental and food sample collection.
- Durable sponge withstands scrubbing.
- Sponge bag with write-on label for ease in labeling samples.
- Decontaminated through gamma irradiation to maintain organism viability and long shelf life.

Recommended pairings (common workflow add-ons)
- Follow-up on seams: After broad sponge sampling, use swab samplers for gasket lines, hinges, and tight interfaces where harborage points often persist.
- Neutralizer matching: Use Letheen formats specifically in areas exposed to quat sanitizers where neutralization is required to protect recovery.
- Controlled-area support: Reinforce adjacent controlled spaces (QA labs, controlled staging) with Texwipe cleanroom wipers and swabs to reduce recontamination around verification activities.
