According to the revised Management Measures for Procurement and Tendering of Shanghai Electric Power Institute, due to work requirements, we are now conducting a rapid procurement of Shanghai Electric Power Institute operating glove boxes numbered SDJU-2025020. Welcome suppliers with corresponding qualifications and capabilities to participate in the quotation. 1、 Procurement requirements (quantity, technical specifications, warranty period, acceptance requirements, etc.) 1. Project overview (1) Brief description: Our school's laboratory plans to purchase a glove box. This glove box is easy to operate and maintain; Suppliers are required to provide comprehensive after-sales services, including equipment installation, debugging, training, maintenance, and parts supply. A glove box is necessary for conducting laboratory experiments without water or oxygen, which can greatly improve work efficiency. Its specific uses include: researching and developing new semiconductor materials and devices; The preparation of optoelectronic devices such as photovoltaic cells and LEDs can improve the quality of scientific research papers, therefore, the investment benefit prospects are promising. (2) Service target: 1) Laboratory researchers at our university: providing experimental platforms for teachers, graduate students, and undergraduate students, supporting scientific research projects and experimental teaching; 2) Enterprise cooperative units: Provide technology research and development and pilot testing services for cooperative enterprises, promote the integration of industry, academia and research; 3) Research institutes: Conduct collaborative research with other universities and research institutes to jointly promote technological innovation. 2. Purchase details, serial number, name, quantity, reference brand, estimated cost (10000 yuan), 1 glove box, 1 super; Inert； Braun 103. Technical index number name quantity Technical index 1 Glove box 11. Internal dimensions of the box: length ≥ 1220mm, depth ≥ 750mm, height ≥ 900mm; Material: 304 stainless steel, thickness 3mm; ★ 2. The large and small transition compartments are integrated on the right side of the box. The diameter of the large transition compartment is ≥ 360mm and the length is ≥ 600mm, while the diameter of the small transition compartment is ≥ 150mm and the length is ≥ 300mm. The connection between the large and small transition compartments and the box is detachable and cannot be welded to the side panel of the box. Physical pictures of the connection parts between the large and small transition compartments and the box must be provided during bidding. ★ 3. The front window of the glove box adopts an O-ring flange window, and the solid O-ring is embedded in the sealing groove. The vacuum sealing method has no break point, strong corrosion resistance, and good sealing performance. When bidding, physical pictures of the O-ring flange window and a schematic diagram of the sealing structure of the flange window need to be provided. 4. A pair of butyl rubber gloves, imported brand. 5. Gas purity: Water<; 1ppm, oxygen<; 1ppm. ★ 6. Gas control valve: Adopting stainless steel electromagnetic integrated valve seat, optimizing pipeline layout and reducing leakage points. Physical pictures of the stainless steel integrated valve seat should be provided during bidding. ★ 7. A water analyzer: measuring range: 0-500ppm. The water probe can be restored to its initial state through a cleaning and regeneration program, and can be reused, avoiding the problem of one-time pollution and disposal. 8. A dual gas purification system: valve control, renewable purification materials, and automatic control of the regeneration process, with automatic water and oxygen removal functions. 9. An imported vacuum pump: can be manually or started through PLC, with a flow rate of ≥ 12m3/h, capable of vacuuming the transition chamber and maintaining pressure balance in the box. The maximum vacuum degree of the vacuum pump is ≤ 2 × 10
