10ml Top empty bottles have a round bottom or a flat bottom. Both types are suitable for injection but round-bottomed bottles tend to be stronger in storing samples. Therefore, the more reliable work should be the automatic sampler of the round bottom bottle. Round-bottomed bottles also tend to withstand higher pressures and are more suitable for temperature increases and are compatible with applications such as derivatization.The round bottom sample bottle is compatible with most automatic samplers, and the sample arm is convenient for carrying the sample bottle from the tray The flat-bottled sample bottle can achieve a high level of heating efficiency during manual head space injection and is suitable for certain types of instruments

The 18mm Screw Headspace with caps with electromagnetic screw seals used for CTC is novel in the headspace vial market dominated by crimping necks. Especially for magnetic caps that are difficult to crimp, screw caps are a convenient choice. 18mm Screw Headspace with caps with aluminum skirt and magnetic center plate, it is easy to crimp and remove the cap. 18mm headspace vial with cap is preferred for the following instruments: Shimadzu. How to choose whether to buy the Headspace Vial with round bottom or flat bottom? The round bottom is stronger, so it is more resistant to the high pressure in the sample Vial during heating. In addition, the vial is easier to slide into the heating block when transported by the magnet. When the vial must run in the instrument with a slight downward trend, a flat bottom may be required.Select the correct Headspace Vial at the bottom and use modern instruments to prepare the entire experiment with highly repeatable samples for accurate analysis.
Aijiren provides Screw Thread Headspace Vial always be applied to Aijiren, Shimadzu, Tekmar, CTC PAL, Varian, Gerstel, Atas, Thermo Scientific autosamplers. Aijiren’s Screw Thread Headspace Vial are all round bottom, this is because A rounded bottom is more sturdy and thus more resistant to the high pressure within the vial during the heating process.

Aijiren’s Headspace Caps often use metal material aluminum, which is soft and convenient for Hand Crimper and Decrimper for sealing. Not only that, the Septa produced by Aijiren is also made of high-quality silicone and ptfe, and is pressed with an exclusive process. This kind of septa is not easy to deform, break, and fall off, and it can also ensure the tightness of the vial.
COD (Chemical Oxygen Demand) digestion vial is a specialized laboratory glassware used for the determination of chemical oxygen demand in water samples. COD is a measure of the amount of oxygen required to chemically oxidize organic and inorganic substances present in water. COD digestion vial typically consists of a glass or plastic vial with a tight-fitting screw cap. The vial is designed to withstand high temperatures and chemical reactions that occur during the COD digestion process.
