1) Autosampler vials
Contingent on the respective manufacturer the most commonly used 12 x 32 mm laboratory vials are indicated with a volume of 1.5 ml, 1.8 ml or 2.0 ml. These vials are made from borosilicate glass of hydrolytic class I, PP or TPX. Divergent sizes are possible up to a volume of 50 ml. Thanks to micro inserts the volume of the laboratory vials can be reduced down to 50 µl.
Once the appropriate laboratory vial has been found the lid is essential. Options include threading, rolled edges or snap rings. The threadings are divided into the different sizes (such as ND9, ND11 etc.), headspace vials and short-thread vials. The selection of lid is based on the closure type and your requirements.
The appropriate lid for every laboratory vial: no matter whether crimp or screw cap, headspace or snap ring cap. Screw caps from PP or snap ring caps from PE with hole, crimp caps from classic aluminum and center tear-off caps are a common material in different laboratories. Magnetic crimp or complete tear-off caps and magnetic screw caps are considered exotic and are mainly used in the pharmaceutical field.
Headspace caps stand out from the previous closures through their overpressure protection.
In the field of chromatography septa play an important role, due to the fact that all lids are equipped with various septa. The 8 most commonly used materials are natural rubber, TEF, PTFE, silicone, aluminum foil and different Pharma-Fix septa.
The resulting characteristics drive the choice of the septum:
