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

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.
