Observing vial and plate recommendations

Incorrect selection of sample vials and plates can lead to issues with system function and performance.

Waters recommends that you observe these usage guidelines for sample vials and plates in the sample manager:

• Vials
  • Use only Waters-certified vials.
  • Ensure that vial holders conform to ANSI/SBS standards.
• Plates
  • Use only Waters-approved plates and cap mats.
  • When selecting a new plate supplier, especially for 384-well plates, measure the plate size to ensure compatibility with Waters’ specifications for the sample manager.
  • To avoid warping plates, do not centrifuge them.
  • Be aware that plates containing samples with high concentrations of organic solvent can give inconsistent results at or above room temperature due to solvent evaporation.
• Covers
  • Use cap mats on sample plates whenever possible.
  • Use pre-slit cap mats/seals and vial caps. Use of non-pre-slit cap mats and vial caps can cause clogging in the wash drainage lines.
  • To prevent sample spillage or needle damage, use only Waters-approved covers on the sample vials.
