How to Prevent Sample Vials Fragmentation

Hawach ensures the accuracy of each sample vial and cap specification, from the initial design to the final photoelectric scanning inspection process, with our strict tolerance control throughout the entire manufacturing process.

Integrity, cleanliness, and uniformity of a sample vial are critical to today’s demanding applications. To prevent contamination and avoid instrument damage, proper selection of spacers is crucial.

The pad of a sample vial may degrade resulting in sample contamination. Rubber pads only stay stable under 90 ℃, and therefore not suitable for high-temperature applications. In general, PTFE-lined silicone rubber spacers are the best choice for all temperatures.

All Hawach sample vials are manufactured under ISO9001 clean environment, and the unique packaging ensures cleanliness and safety during transportation.

How to prevent debris:
1. Select a PTFE-lined spacer to prevent the spacer material from entering the sample;
2. Almost complete removal of debris using pre-perforated spacers;
3. For highly sensitive samples, we recommend using PTFE lining spacers as the PTFE layer acts as a barrier to chemical corrosion.
The sealing of a sample vial is also an important factor affecting the experimental result.
