Focused on Sterility & Biosafety Solutions
Wenzhou TOONE Biotechnology Equipment Co., Ltd. has been deeply engaged in the field of microbial testing for more than ten years. As a National High-Tech Enterprise and one of China’s core suppliers of sterility testing consumables and equipment, TOONE is committed to the philosophy of “Building the Brand with Quality, Protecting Safety with Expertise.”
Focusing on microbial quality control needs in the pharmaceutical, food, CDC, and chemical industries, TOONE provides a complete range of solutions integrating sterility testing pumps, disposable sterility test canisters, and filtration consumables. All products comply with the standards of the Chinese Pharmacopoeia, deliver performance comparable to international brands, and offer outstanding cost-effectiveness.
TOONE fully enclosed sterility test canisters (compatible with intelligent sterility testing pumps such as TW-APL01) are designed based on membrane filtration technology for sterility testing of pharmaceuticals, biological products, sterilized medical devices, and more. The system enables fully enclosed filtration with no cross-contamination and highly reliable results.
Key AdvantagesFully Enclosed Design：Integrated sterile tubing allows filtration, rinsing, media addition, and incubation to be completed within a completely closed system, effectively preventing external microbial contamination.
Safe and Durable Materials：The main body is made of AAS material, offering excellent cleanability and corrosion resistance.
Strong Compatibility：Compatible with single-channel, dual-channel, and multi-channel drainage systems, adapting to various sterility testing pumps and meeting both laboratory-scale and batch-testing requirements. Standard configuration includes a 0.45μm sterile membrane filter with ≥99.99% retention efficiency.
Convenient Operation：Combined with automatic pump control, culture media can be added directly after filtration for in-place incubation without transferring the membrane, significantly reducing contamination risk and improving counting accuracy and testing efficiency.
