PFA Ultra-clean Fresh-keeping Box - The Ideal Choice for Precise Sample Management in Laboratories
Product Overview
The PFA fresh-keeping box is specially designed for ultra-clean laboratory environments. It is made of high-purity PFA material, featuring corrosion resistance, high-temperature resistance, and an extremely low background value. Multiple sizes are available, and it is equipped with a snap-on sealing lid to ensure the safety and cleanliness of samples during storage, transfer, cleaning, etc. It is an important tool for laboratories in fields such as semiconductors, new materials, and precision chemistry.
Core Advantages
1. Ultra-pure Material Guarantee
- Made of PFA (Perfluoroalkoxy), it is resistant to strong acids, strong alkalis, and organic solvents, and can withstand temperatures ranging from -200℃ to 260℃.
- After cleaning, the background value is as low as the ppt level, effectively avoiding trace contamination and meeting the strict requirements of high-sensitivity experiments such as those in the semiconductor field.
2. Sealing and Leak-proof Design
- The snap-on sealing lid design fits tightly with the box body, preventing leakage and volatilization and ensuring the stability of samples.
- The transparent box body and lid allow for direct observation of the state of the contents.
3. Multi-functional Application Scenarios
- Sample Storage and Transfer: Suitable for the temporary storage of precision materials such as wafers, electronic chemicals, and high-purity reagents.
- Soaking and Cleaning: It can withstand processes such as acid washing and can be reused, reducing the cost of consumables.
4. Flexible Size Options
- Multiple specifications (unit: mm) are available:
- Small: 80×80×80 (for portable single-sample storage)
- Long: 200×80×80 (for strip-shaped or multi-sample partitioned storage)
- Medium: 350×240×120 (for routine experimental batch processing)
- Large: 400×250×150 (For soaking large-volume reagents or devices)
Applicable fields
- Semiconductor manufacturing: Ultra-clean environment operations for wafers, photoresists, etching solutions, etc.
- New material R & D: Protection of samples of nanomaterials, high-purity metals, and functional coatings.
- Analytical testing: Sample pretreatment and storage in trace analysis such as ICP-MS and LC-MS.
- Biomedicine: Long-term stable storage of highly active ingredients and standard substances.
Usage and maintenance
- Cleaning suggestions: Use ultrapure water or laboratory-grade cleaning agents and cooperate with an ultrasonic cleaner to thoroughly remove dirt.
- Avoid sudden high-temperature changes: After long-term use at high temperatures, it is recommended to let it cool naturally to room temperature before opening the lid.
- Storage environment: Store in a dry and dark place, away from sharp objects to prevent scratching.
