About the Properties and Features of Sample Vials

The sample vials are commonly used in various experiments. The material of the sample vial is usually neutral borosilicate glass, which will not cause the precipitation of metal ions and affect the analysis results. In order to prevent the sample from being adsorbed, some sample vials are also silanized. Sample vials are made of high-quality glass raw materials in the category-Class 1 borosilicate glass with an expansion coefficient of 51. This type of glass does not affect the analytes in your sample matrix, which means that vials are an indispensable solution for your valuable samples.

The newly born sample vial
The main contents can be seen clearly via the sample vial. It is for this reason that external light can easily pass through the container, causing the contents to change and deteriorate. At present, a colorless and transparent sample vial that can block ultraviolet rays has attracted widespread attention. The production method is to add a metal oxide that absorbs ultraviolet rays into glass. At the same time, the complementary color effect is used, and some metals or their oxides are added to fade the colored glass.

Sample vial features
1. Extremely high inertness: The inertness of the sample vial can reduce the peak variability of the analyte.
2. Consistent performance: Each batch of the sample vial has consistent performance, which saves you more time for troubleshooting and re-running samples.
3. Certificate of analysis: The sample vial is equipped with an analysis certificate, which can guarantee you that it can work normally even in a harsh environment.
4. Can be matched with various bottle cap designs: sample vials can use your existing 2ml autosampler caps, bringing more convenience to your inventory management.
5. Fewer septa issues: HAWACH has continued to improve septa to actively reduce leaching, chipping, blocking, pushing, stiffening, and adsorption issues.

Chromatography vials are a typical type of sample vials and are widely used in the market.
1: Compared with others, chromatography sample vials are more cost-effective and more durable.
2: The chromatographic sample vial rack can be marked with numbers and other symbols, which can make the experiment more accurate.
3: It can be stacked in the case of vacancy and full, effectively saving workspace.
4: The product is made of high-quality PP plastic and it will not deform when it comes into contact with organic solvents and general acid and alkali liquids.

How important is the quality of a chromatography vial?
If the tolerance is not strictly controlled, the labeled size and wall weight of the autosampler sample vial may be different, which will affect the sample volume in the sample vial. It is very important for a small number of samples. Our strict tolerance control runs through the entire manufacturing process, from the initial design to the final photoelectric scanning inspection process, to ensure the accuracy of each sample vial and cap specifications.

The integrity, cleanliness, and uniformity of chromatographic sample vials are critical to today’s demanding applications. All HAWACH sample vials are manufactured in an ISO9001 clean environment, whose unique packaging guarantees cleanliness and safety during transport.

The HAWACH sample vial has excellent sealing performance, which can effectively avoid sample evaporation. The vial and the corresponding 11 mm aluminum cap can be easily and quickly combined with the jaw capping tool. The vial can withstand heat and pressure, and can also be used for chemical reactions. Especially for vials with white open caps and thick PTFE / silicone septa, they can be used as anhydrous and oxygen-free reaction bottles.
