Transparent jaw headspace bottleUsually made of high borosilicate glass, it has the characteristics of high transparency, high temperature resistance, corrosion resistance, etc. It can clearly observe the state of the sample and has good resistance to common acidic and alkaline chemicals. Widely used in fields such as biological research, chemical analysis, environmental monitoring, etc., it can be used for storing and transporting biological samples, chemical reagents, environmental water samples, etc.

selectTransparent jaw headspace bottlePossible factors to pay attention to:

Material purity:

Priority should be given to high borosilicate glass or special glass with surface inerting treatment to avoid sample adsorption or container corrosion.

Sealing performance verification:

Check the strength of the magnetic steel, the elasticity of the sealing gasket, and the flatness of the bottle mouth to ensure that there is no air leakage during long-term use.

Blank test can be conducted: After the bottle containing pure solvent is left to stand for 24 hours, the sample is tested to confirm that no impurity peaks appear.

Dimensional accuracy and compatibility:

Accurately measure the clamp size of the instrument and select the appropriate bottle mouth diameter (such as 22.5mm standard specification).

Confirm the matching degree between the inner diameter of the bottleneck and the automatic injection needle to avoid difficulty in injection or excessive dead volume.

Preprocessing and Quality Control:

Newly purchased bottles need to undergo strict pre-treatment (such as soaking in chromic acid solution, ultrasonic cleaning with pure water, and muffle furnace roasting).

Require suppliers to provide batch testing reports, with a focus on indicators such as heavy metal leaching and particle count.

Brand and after-sales service:

Choose reliable brands to ensure stable quality and compatible accessories.
