1. Sample Cleanliness:
Item Pre-treatment: It is recommended to pre-purify items in a clean environment (such as a Laminar Flow Cabinet or pass-through window) before placing them inside. The purification level should meet requirements and can refer to international standards. Avoid introducing dust, grease, or other impurities.
Oven Cleaning: Before use, wipe the cavity of the oven and shelves with a lint-free cloth and specialized cleaning agent (such as isopropanol). If necessary, run the oven empty first for pre-purification.
Minimize Door Opening: Operate quickly, reduce the number and duration of door openings to prevent external contamination.
2. Internal and External Filters:
Regular Replacement: Replace HEPA/ULPA filters according to the manual or manufacturer's recommended schedule. This is key to maintaining cleanliness. If frequently drying items with more impurities, replace filters earlier.
Handle with Care: Wear lint-free gloves during replacement, avoid touching the filter material, and ensure proper sealing during installation.
3. Safe Operation:
Temperature Compliance: Set the required temperature and also set the upper limit of the over-temperature protection device to not exceed the item’s heat resistance limit to avoid damage.
Prohibited Items: Do not place flammable, explosive, volatile, or strongly corrosive items inside.
Burn Prevention: During operation and after shutdown, the oven remains hot. Wear high-temperature resistant lint-free gloves when operating.
Heat Dissipation: Ensure sufficient clearance around the equipment for proper ventilation.
4. Specifications and Maintenance:
Keep air inlet and outlet unobstructed.
Handle with care to avoid impact and particle generation.
Place items properly, leaving gaps between them to ensure uniform airflow.
Perform regular maintenance: clean the chamber, calibrate the temperature controller, verify cleanliness and drying effectiveness, and keep records.
Strictly follow the equipment’s specific manual requirements.
