The integrity, cleanliness and uniformity standards of Aijiren 4ml vials (HPLC autosampler vials) are very high. The 4ml sample bottle provided by Ajiren is usually used with HPLC, Aijiren, Shimadzu and Waters and other autosamplers. When the instrument is running, the flat-bottomed sample bottle is suitable for downward movement. The flat-mouth vial has a larger contact area with the septum and has a stronger seal.
