Vial Size ND20 Headspace Vials 20MM Aluminum Seal Avoid Excessive Evaporation

The long-term seal is formed by the aluminum crimp compressing the bottom of the stopper flange to the top surface of the vial crown. However, prior to the application of the aluminum crimp, the seal provided by the interference fit (typically 2–10%) of the stopper plug in the vial bore must provide an initial seal (see Fig. 1 Sealed Vial).

Aijiren headspace vials come in two basic sizes (10 mL glass vials and 20 mL glass vials; Crimp caps are most common however many customers use screw sample and application dependent; clear glass vials and amber vials are available; 11 mm caps, 18 mm caps, and 20 mm caps are engineered to prevent sample contamination while providing consistent, secure seals. Aijiren headspace vials come in both flat bottom and round bottom styles for use in a wide variety of headspace instrument platforms.

Using poor-quality vials (or the wrong vials for your application) can cause sequence problems, unnecessary downtime, expensive repairs, and the loss of precious samples Aijiren vials are the only vials that deliver time and cost savings: • Reduced labor: Our short-thread screw-top vials make screwing/ unscrewing the cap up to 30% faster.

vial and the crimped aluminum cap. This forms an excellent seal preventing evaporation. The septum stays seated during piercing by the autosampler needle. The crimp cap vial requires crimping tools to carry out the sealing process. For few samples, manual crimper tools are the best choice. For large numbers of sample, automated crimpers are

Seal the vial with teflon tape and parafilm. I make the heater from the small cylinder shaped ceramic resistors which are usually available from the electronics shop. I found some green ones of 100 ohms which are a good size. Place just the tip of the vial with the solid pellet in the heater, with the vial at ~45 degrees from vertical.

A steam sterilizer dries the load after sterilization by drawing a deep vacuum in the chamber (post- conditioning phase). A vacuum level of 1.0 to 2.0 psia (6.9 to 13.8 kPa) is recommended for efficient drying. At 1.0 psia (6.9 kPa) chamber pressure, water boils at 38.7°C (101.7°F).
