Use only vial caps and well plate covers as outlined below.

Vial Caps and Septa

Use only talcum-free, unfilled silicone/PTFE-based septa. Talcum and seal-filler particles may cause backpressure issues or blockages in the system.

Example of caps that meet the requirements:
Thermo Scientific bonded red PTFE/white silicone vial screw thread caps and septa

Well Plate Cover Mats

Use unfilled silicone cover mats.

Example of mats that meet the requirements:
Thermo Scientific WebSealTM 96-well non-coated plastic microplate with WebSeal silicone mats

Well Plate Sealing Tape

Use sealing and resealing tape without adhesive at the cavity area. Adhesive at the cavity area can lead to injection needle contamination.

Example of tape that meets the requirements:
Thermo Scientific WebSeal 96-well non-coated plastic microplate with WebSeal sealing tape with 3 layer no adhesive at cavity area

Do not use well plate seals that are likely to result in seal material being punched out by the autosampler needle. For example, sections of aluminum tape may be punched out of aluminum well plate sealing tape and deposit in the needle seat.
