Etelux Vacuum Glovebox Lab2000 with Purification System

This glove box (Lab2000) is specifically designed for scientific research and development requiring ultra-pure environments. Its primary function is to remove O₂, H₂O, and organic gases, making it ideal for applications that demand water-free, oxygen-free, and dust-free conditions. The glove box is widely used in the production and research of lithium-ion batteries and materials, semiconductors, supercapacitors, specialty lighting, laser welding, brazing, material synthesis, OLED manufacturing, and MOCVD processes. Additionally, it is suitable for biological applications such as anaerobic and hypoxic cell culture.

The system primarily comprises a sealed chamber, a transfer chamber, a gas circulation system (including purification and regeneration units), water and oxygen monitoring, a control system, and a vacuum system. The gas circulation operates in a closed loop, ensuring zero leakage throughout the process. An integrated pressure control system maintains constant pressure within the chamber for optimal performance.

3.1 Control Method: Features self-diagnosis, automatic restart after power failure, pressure control, and adaptive functions. Offers automatic operation, circulation management, password protection, and vacuum chamber control—all accessible through an LCD display. Unit operation is managed via a Siemens PLC touch screen interface.

3.2 Pressure Control: Maintains the pressure of both the glove box and transition chamber at predetermined set values.
a) Users can freely set the working pressure range between +12.5 and -12.5 mbar; the PLC automatically adjusts chamber pressure within this range. The default working pressure range is -1 to +3 mbar.
b) If box pressure exceeds 12 mbar, the PLC automatically activates the safety valve to relieve excess pressure, protecting gloves, equipment, and internal materials.
c) Fine adjustments to chamber pressure can be made using a convenient foot pedal.

3.3 Foot Pedal: Allows operators to easily control glove box pressure, providing hands-free convenience during operation.

4. Circulation System (Including Purification and Regeneration System)

4.1 Materials: Utilizes German BASF and American UOP purification materials, along with German Proud valves. The host system features a modular design, integrating a fully automatic electronic gas solenoid valve group, PLC controls, circuits, circulation pump, purifier, and display into a single independent unit for compactness and efficiency.

4.2 Control: Maintains water and oxygen levels below 1 ppm to ensure an ultra-pure environment.

4.3 Adjustment: All adjustments—including heating, evacuation, purification, and regeneration—are controlled via the PLC touchscreen. The entire process, except for 2.5 hours of ventilation, operates automatically and does not require human supervision.

4.4 Working Gas: Compatible with helium (He), nitrogen (N₂), or argon (Ar) as circulating gases.

4.5 Circulating Fan: Features a high-speed, variable-frequency fan with a capacity of 0–100 m³, microprocessor-controlled, constructed from stainless steel, and pressure-tested for reliability.

4.6 Purification Column: Equipped with a single column containing 5 kg of German BASF deoxygenation material and 5 kg of UOP high-efficiency absorbent from the United States, ensuring extended purification capacity. The system can remove up to 2.2 kg of water and absorb 63 liters of oxygen.

4.7 Purification Valve: Fully automatic electric valve for precise and efficient operation.

4.8 Filter: High-efficiency filter with a 0.3-micron pore size, compliant with HEPA standards.

4.9 Regeneration: Regeneration restores the purification system for continued use. The process requires a gas mixture of helium/H₂, nitrogen/H₂, or argon/H₂, with hydrogen comprising 10% of the mixture. The catalyst can be regenerated 10–12 times, with each regeneration cycle lasting 6–12 months. Total catalyst lifespan can reach up to 10 years, depending on usage and maintenance.
