Application

 

1. Trace & Ultra-Pure Analysis

ICP-MS / Elemental Analysis: Ensures accurate data for ultra-low concentration metal detection, eliminating container background interference.

Ultra-High-Purity Chemical Storage: Safely stores photoresists, high-purity acids, and solvents for semiconductor and photovoltaic industries.

Ultra-Clean Sample Handling: Ideal for processing ultra-low background samples like polar ice cores and deep-sea water.

 

2. Biopharma & Advanced Therapies

Precious Biorepository: Enables long-term, stable storage of viral vectors, antibodies, and cell therapy intermediates.

Critical Process Interim Storage: Used for handling and transferring container-sensitive critical materials in vaccine and gene therapy production.

 

3. Demanding Chemistry & Frequent Sterilization

Highly Corrosive Chemicals: Handles strong acids, oxidizers, and specialized organic solvents incompatible with plastics.

High-Frequency Sterilization & Industrial Sampling: A durable, safer alternative to glass for repeated high-temperature sterilization in fermentation and microbiology applications.
