Chex-All® Sterilization Pouches and Tubes are intended to be used to enclose another medical device, in a single or double pouch configuration, that is to be sterilized by a health care provider using:

Hospital size sterilizer cycles

• Gravity steam at 121°C (250°F) for 30 minutes; 25 minutes dry time
• Pre-vacuum steam at 132°C (270°F) for 4 minutes; 20 minutes dry time
• Pre-vacuum steam at 135°C (275°F) for 3 minutes; 16 minutes dry time

Tabletop sterilizer cycles:

• Pre-vacuum steam at 132°C (270°F) for 4 minutes; 30 minutes dry time

Ethylene Oxide sterilization cycles:

• Ethylene Oxide (EO) with a concentration of 736 mg/L at 55°C (131°F) and 50% to 60% relative humidity for 60 minutes. Aeration time of 8 hours at 60°C (140°F).

Chex-All sterilization pouches and tubes can be used for steam sterilization of devices with lumens at maximum load as the following:

Metal lumen: 7 inch long, 3.2mm internal diameter
Plastic lumen: 5 inch long, 2.0 mm internal diameter.

Suitable Lumen cycles:
Hospital size sterilizers: pre-vacuum cycles with 132°C-4.0 min exposure (20 minutes dry time) and 135°C-3.0 min exposure (16 minutes dry time).
Table-top sterilizers: pre-vacuum cycle with 132°C-4.0 min exposure (30 minutes dry time).

Chex-All sterilization pouches and tubes can be used for steam sterilization in double pouch configuration, in gravity 250°F-30 min exposure cycles (25 minutes dry time) and in pre-vacuum 270°F-4 min exposure cycles (20 minutes dry time).

The Process chemical indicators on the Chex-All sterilization pouches and tubes are intended to demonstrate that the device has been exposed to the steam or EO sterilization process and to distinguish between processed and unprocessed pouches. The chemical indicators change from crème to gray/black after exposure to steam and from beige-pink to green after exposure to ethylene oxide.

If stored according to the recommended conditions, the products before sterilization have a maximum shelf life of 2 years from the date of manufacture. The pouches are intended to allow sterilization of the enclosed medical device(s) and to maintain sterility (SAL≥10-6). The subject device is intended and has been validated to maintain sterility of the enclosed devices for 30 months after steam sterilization and 12 months after EO sterilization.

The maximum pouch load is 2.65 lb. (1.2 kg) or less. The maximum pouch load for table-top sterilizers is 1.10 lb. (0.5 kg) or less. The maximum pouch size for use in table-top sterilizers is 13"x18".

The Chex-All® Sterilization pouches and tubes are made from a medical grade porous paper thermally sealed to a plastic film on the left, right, and bottom of the pouch. The top side is open to insert medical devices to be sterilized and to seal the pouch. They are available either pre-manufactured self-seal or heat-seal sizes or in a roll of heat-seal tubing for the customer to cut the pouches to their required size.

The pouches also contain chemical process indicators used to demonstrate that the pouches have been a subject of either a steam or ethylene oxide sterilization process.

All Chex-All sterilization pouches and tubes are flat and include the following products: Chex-All Heat-seal sterilization pouch, flat; Chex-All Heat-seal sterilization tube, flat, sold in rolls; Chex-All II Self-seal sterilization pouch, flat; Chex-All III Self-seal sterilization pouch, flat.
