This product is suitable for leak testing of packaging bags, bottles, tubes, cans, and boxes in industries such as food, pharmaceuticals, medical devices, daily chemicals, automotive, electronic components, and stationery. It can also be used to test the sealing performance of samples after drop and pressure tests. The test helps detect through-wall defects such as leaks and cracks, as well as airtightness defects, thereby preventing product leakage, contamination, resource loss, and spoilage.
① Significantly reduces the oxygen content in the storage environment, lowering the risk of oxidation of easily oxidizable substances;
② During the vacuum formation process, 99.99% of microorganisms and suspended bacteria are removed from the storage environment, reducing the chance of product contamination;
③ Microbial activity is reduced in a vacuum state, extending the shelf life of materials by 3-5 times, preventing mold and chemical degradation;
④ The cleanliness of the vacuum environment can reach Class 100, suitable for long-term storage of products requiring high cleanliness;
⑤ The vacuum state effectively prevents temperature changes, making it the preferred method for storing heat-sensitive substances;
⑥ By isolating oxygen and moisture through a vacuum environment, it inhibits metal oxidation and moisture damage to electronic components, improving protection efficiency by over 90%;
⑦ The vacuum environment can effectively filter sound waves, creating an ultra-quiet environment;
⑧ Upgraded appearance: While improving the overall performance of the equipment, the appearance has been upgraded to be exquisite and elegant;
⑨ Guaranteed after-sales service: A comprehensive after-sales service network covering most parts of the country is provided to ensure worry-free use for users (Note: excluding a very few remote towns and villages);
⑩ Technical support solutions: Provides multi-faceted technical guidance including videos, telephone support, and online video tutorials, intuitively demonstrating equipment performance and operation methods to help users quickly master the equipment.
① Outer Casing Material: Made of selected high-quality cold-rolled steel plate (Q235), precisely formed by CNC machining. The surface is treated with phosphating and anti-static powder coating, creating a robust casing. It is anti-static, corrosion-resistant, and scratch-resistant, ensuring long-lasting quality;
② Working Chamber: Made of thickened stainless steel, possessing excellent high-temperature stability and corrosion resistance, with a smooth surface for easy cleaning;
③ Door Seal: Resistant to thermal oxidation aging, maintaining elasticity and sealing integrity for a long time, effectively preventing heat loss and ensuring the stability of the working chamber temperature;
④ Shelves: Standard configuration includes high-corrosion-resistant chrome-plated mesh shelves with surface hardening treatment, providing oxidation resistance, acid and alkali resistance, and stable load-bearing capacity; supports flexible customization of various materials and hole types, including stainless steel, alloy, and Teflon, perfectly matching the demanding requirements of pharmaceutical, electronics, and scientific research applications, providing precise and reliable load-bearing solutions for high-end drying processes.
⑤ Some large-capacity models are equipped with high-performance silent universal wheels, combining flexible movement and stable parking, suitable for precision laboratories and high-end industrial environments, showcasing attention to detail and user-friendly design.
⑥ Optional activated carbon adsorption module is available, meeting cleanroom emission standards;
⑦ Supports customized chamber volumes (10L~2000L), compatible with various loading methods such as trays and racks;
