Glove Box Fume Hood
A Glove Box Fume Hood is a specialized laboratory device that combines features of a glove box and a fume hood to provide enhanced containment and safety for handling hazardous or sensitive materials. Below is a concise overview based on available information:
Key Features and Functions:
- Purpose: Designed for containment of highly toxic or sensitive materials, such as Active Pharmaceutical Ingredients (APIs), Highly Potent APIs (HPAPIs), or air-sensitive substances. It protects the operator, the environment, and the materials being handled.
- Containment: Unlike a standard fume hood, which primarily extracts hazardous fumes via ventilation, a glove box fume hood is a sealed enclosure with glove ports, offering a higher level of containment (e.g., below 30 ng/m³ for certain processes).
- Airflow: Equipped with HEPA filters for laminar airflow, often meeting ISO 5 cleanliness standards. It can feature dual HEPA filtration for both inlet and exhaust, ensuring a clean internal environment and safe air recirculation or exhaust.
- Design: Typically includes transparent panels (e.g., acrylic, glass, or static-dissipative PVC), glove ports for manipulation, and transfer ports (e.g., airlocks or RTP ports) to move materials without breaking containment.
- Applications: Used for handling hazardous chemicals, biological samples, or air-sensitive materials in industries like pharmaceuticals, oncology, and research. It supports equipment like balances, ovens, and FTIR within the enclosure.
Glove Box vs. Fume Hood
- Fume Hood: An open system that extracts toxic vapors, gases, or aerosols via ventilation, primarily protecting the operator. Suitable for processes with a Time-Weighted Average (TWA) exposure value above 400 ppm. Not ideal for highly hazardous substances or closed-system requirements.
- Glove Box: A sealed, enclosed system that protects the operator, product, and environment. Ideal for processes requiring a controlled atmosphere (e.g., inert gas like nitrogen or argon) or handling highly toxic substances with TWA below 1 ppm.
- Glove Box Fume Hood: Combines the sealed containment of a glove box with advanced filtration and exhaust systems of a fume hood. It can operate under negative pressure to protect operators or positive pressure to protect samples, offering versatility for applications like HPAPI processing or biohazard containment.
Specific Features
- Filtration: Often includes HEPA or ULPA filters for particulate removal (down to 0.3 microns) and optional carbon filters for additional protection against gases or vapors.
- Materials: Constructed from materials like stainless steel, polypropylene, or acrylic, chosen based on chemical compatibility and application needs (e.g., static-dissipative PVC for static control).
- Customization: Options like double-safe waste chutes, continuous liners, or gas purification systems for inert atmospheres (e.g., <1 ppm H₂O and O₂) are available.
- Safety: Third-party testing confirms containment levels, and features like negative pressure blowers or leak-tight barriers ensure operator safety.
Use Cases
- Pharmaceuticals: Handling APIs, HPAPIs, or compounding non-hazardous drugs in a sterile environment.
- Biological Research: Safe manipulation of pathogens or sensitive biological samples.
- Inert Atmosphere Work: Processing air-sensitive materials (e.g., hygroscopic or pyrophoric substances) under nitrogen or argon.
