钳口样品瓶，用于薄型密封

Autoclavable, easy to maintain. A vial is used to store or as a closure type,in order to prevent contamination.

Regular crimp seal vials are normally used for performing derivatization reactions, when no pressure or heating is involved. These vials are at times tapered, or have special inserts that allow the recovery of small volumes of sample from them.

薄型密封垫样品瓶具有更厚的瓶口。此类样品瓶瓶口更大，在固相微萃取应用中可以容纳更薄的隔膜。此类样品瓶可使用 20mm 厚的薄型隔膜（<0.030 英寸）并且依然保持良好的密封性。有关瓶盖的选择，请参阅固相微萃取样品瓶部分：薄型密封垫钳口样品瓶的瓶盖。
