Vials are suitable basically to inject samples from an autosampler. Autosampler needle pierces through the cap during injection and withdraws the required aliquots of sample from the vials. Screw top vials (volume 7 mL, clear glass vial, O.D. × H 17 mm × 60 mm, thread 15-425) are used on many autosamplers. Screw caps are available as solid caps with aluminum liner. Solid phenolic caps can withstand a maximum temperature of 205°C.
Sterols and hopanoids are chemically and structurally related lipids mostly found in eukaryotic and bacterial cell membranes. Few bacterial species have been reported to produce sterols and this anomaly had originally been ascribed to lateral gene transfer (LGT) from eukaryotes.
