Crimp neck bottles, made of 1st hydrolytic class glass.
This glass is very resistant, has a low expansion coefficient even at high temperatures, and has excellent chemical resistance to acid, neutral and even alkaline solutions.
Headspace vials might differ in
• Volume (5 mL, 10 mL, 20 mL)
• Rounded or flat bottom
A rounded bottom is more sturdy and thus more resistant to the high pressure within the vial during the heating process. Furthermore the vial slides more easily into the heating block when being transported by a magnet. A flat bottom might be necessary when vials have to run within the instrument on a slightly downwards tendency.
• Clear/amber glass
• With/without label and filling lines
• Upon request with a barcode label
