2.About the choice of cap
The sealing effect is good without any tools.
Aluminum jaw, good sealing effect, reducing the possibility of sample volatility;
High-temperature experimental environment, more resistant to high temperature;
To be used with jaw tools.
The sealing effect of the bayonet cap is not as good as the other screw cap and jaw cap;
The push-fit bayonet cap is ideal for storing powder samples and is not suitable for transporting liquids;
If the fit of the cap is very tight, the cap will be difficult to close and may break.
Integrated septa and cap
Ensure that the septa and the cap are always together during transportation and when the cap is placed on the sample vial;
Prevent the septa from falling during use;
Avoid excessive evaporation and keep the vial properly sealed.
The glass sample vial is generally divided into low boron and neutral, the difference is that the content of borosilicate and the physical and chemical properties of the glass are also different. HAWACH can provide sample vials of two materials. For high-throughput laboratories, low borosilicate glass is recommended.
HAWACH sample vials are produced according to the requirements of the international standard, which can reduce your consumption in the experiment and save time. This series of products reduces the analysis error caused by ghost peaks, syringe damage, and septa movement, which can largely avoid analysis failure and achieve sample reuse.
