Product Introduction

The ZW-808A Sterility Tester is a disposable, fully enclosed collection culture unit for配套 use. It features an integrated, stainless steel housing design: constructed entirely of L304 food-grade stainless steel, meeting the high cleanliness requirements of sterile and microbiological rooms. It enhances the lifespan of the instrument and reduces costs associated with repairs and replacements due to rusting issues commonly found in traditional collection culture units. The housing design eliminates any dead corners to prevent corrosion from chemicals. It operates based on the principle of directed peristaltic pressure through the sterility tester, retaining microorganisms in the microporous filter membranes (0.22µm x 47mm or 0.45µm x 47mm) of the sample. The inhibitory components are removed by rinsing the filter membranes, and then the required culture medium is directly introduced into the fully enclosed filter collection culture unit via the injection pipeline. It is then placed in an incubator for sterile culture.

Application Fields

Pharmaceutical Industry:无菌 testing for pharmaceuticals (injections, oral preparations, sterile APIs), and microbiological limit testing for medical devices (syringes, catheters, implants).

Food & Beverage:无菌 verification for bottled water, juices, dairy products, canned goods, etc., to detect the presence of pathogenic bacteria or contaminants.

Cosmetic Industry: Microbial testing for sterile cosmetics (such as eye products, injectable skincare) meets industry hygiene standards requirements.

Environmental Monitoring: Microbial sampling and culturing from pure water, industrial wastewater, and air purification systems to assess the sterility of the environment.

Research & Experimentation: Sterilization filtration of samples in microbiological studies, isolation of target strains, and verification of sterile operations in biological laboratories.

Key Features

1. New Pump Head: Eccentric tensioning for easy and quick operation.

2. The transmission system of the intelligent bacteria-collecting instrument employs a low-speed, high-torque motor for direct drive, thereby reducing input power and the surface temperature of the body, with noise below 50 db.

3. The蠕动泵 features a safety protection device that automatically stops operation when the switch is turned on quickly, preventing operational errors from causing harm to individuals.

4. The whole machine features an integrated ultra-small design with L304 stainless steel, minimizing the space occupied by the operation console.

5. Speed control utilizes a stepless variable-speed method, offering simple and direct operation with a pause memory function.

6. Foot switch utilizes imported aviation waterproof connectors, controls electrical appliances at ultra-low voltage, ensuring no risk of electric shock injury.

7. The casing surface is mirror-polished for easy disinfection and cleaning.

8. Drainage trays are available in split-type and on-machine rotating styles.

9. All installation openings on the body have been sealed with waterproofing, effectively preventing liquid from渗入the interior.

10. Customizable for client requirements, we can add product retrieval functionality, with the freedom to disassemble and retrieve the support stand, catering to the unique needs of retrieving expensive items and product sterilization.
