Products
Compressed paper-based animal bedding (paper tissue material)
Compressed paper bedding made from tissue-paper production scrap, optimized for nesting, high expansion on use, absorbency, and reduced contamination risk; subject to periodic external contaminant analysis.
Chlorine dioxide gas-generating stick devices (rapid and sustained-release variants)
Stick-type chlorine dioxide gas-generating devices that release gas on activation; variants available for rapid high-concentration exposure for containers and sustained low-level release for ongoing hygiene management of shared items.
Low-concentration hydrogen peroxide fumigation systems
Portable and room-scale vaporized hydrogen peroxide generators for environmental sterilization validated to achieve multi-log reduction across volumes from small pass-throughs to large animal rooms.
Automated cage washers and rotary washing systems
Custom-dimension cage-washing equipment with multi-stage hot-water pump washing and steam spray finish, available in stationary and rotary configurations for facility-scale sanitation.
Portable bedding suction cleaner (cyclone + 2 µm filtration)
Compact, transportable bedding cleaner using cyclone plus 2 µm filtration to remove bedding from cages; capable of handling wet bedding and featuring washable filters and large-diameter hose to reduce clogging.
Custom animal cages and rack systems (rodent to NHP)
Design and manufacture of species-specific housing including NHP cages, dog/pig pens, marmoset cages and small-animal resin cages with materials selected for transparency and heat resistance; options for automatic watering and ILAR-compliant dimensions.
