2 mL, Standard Opening, 8-425 screw thread vials
Although most laboratories have switched to 9 mm screw thread vials for a wider opening while still being autosampler compatible, some labs use 8-425 vials for storing solvents. The standard opening 8-425 vials have more threads per inch, so there is less likelihood that volatile solvents will evaporate over time.
