• Pouch or wrap items to preserve sterility after processing. Use only protec-
tive coverings designed and recommended for use with steam sterilization.
• Do not wrap items too tightly. Steam penetration will be affected if an item
has excessive wrapping.
• Do not stack trays on one another. Using Midmark’s standard tray rack and
trays provides proper tray spacing.
• Position loads on trays with appropriate space between items. Adequate
space is required between items to allow proper steam flow and drying.
• Place unwrapped items on a towel.
Listed below are maximum recommended loads for each tray:
‡ Packs to have a minimum of 1/4 in. (6.3 mm) space between each other and
away from all sterilizer surfaces.
