Product Advantages
- Exceptional chemical resistance: Exhibits extraordinary tolerance to strong acids, alkalis, and various organic/inorganic solvents.
- Low background values: Extremely low leaching and extraction levels, making it suitable as a sample vial for long-term storage of high-purity reagents and standards without worrying about impurity precipitation.
- Compatibility:
- Open-top design allows autoclaving; flat outer bottom enables heating on hot plates or steam pressure.
- Can be used as a digestion vessel with our company's perforated electric digestion apparatus for medium-low pressure heating experiments.
- Recommended temperature limits: ≤160°C when sealed; up to 250°C when open.
- Design features:
- Available in U-shaped, V-shaped, and flat bottom designs per experimental requirements:
- U-bottom design facilitates sample transfer.
- V-bottom design optimizes collection of small sample volumes.
- Flat bottom design ensures uniform heating and easy sliding.
- High transparency: As a digestion vessel or tube, it allows real-time observation of in-tube sample reactions.
