GORE LYOGUARD Freeze-Drying Trays are fully enclosed, single−use, disposable containers that use a unique ePTFE membrane technology to both prevent cross−contamination and fly-out, and enable the free exchange of moisture vapor during lyophilization.
The ePTFE tray surface is chemically inert, non-shedding, and biocompatible and includes a convenient fill cap. The flexible, thin−film polypropylene tray bottom closely conforms to dryer shelves for efficient and uniform heat transfer.
These autoclavable trays are designed to be direct replacements to open trays and are compatible with most freeze-drying processes.
- Bulk API lyophilization up to 1800 ml

Other External Materials
The GORE LYOGUARD Freeze-Drying Tray is intended for use as a processing aid in the production of materials that are frequently subject to FDA regulation. The regulatory status of the end product resulting from a manufacturing process, such as a pharmaceutical, does not transform a manufacturing apparatus into a medical device. The GORE LYOGUARD Tray is neither classified nor regulated as a medical device.
Tray Manufacturing and Quality
Assembly operations for the GORE LYOGUARD Trays are conducted in an ISO 8 clean room with particle monitoring to ensure that the room is operating to at least ISO 7 (class 10,000) during operation. Final inspection and packaging are conducted in a controlled environment.
GORE LYOGUARD Freeze-Drying Trays are manufactured in a manner that adheres to relevant current Good Manufacturing Practices (cGMP), as defined in a quality system certified to ISO13485, and ISO15378.
GORE LYOGUARD Freeze-Drying Trays are 100% visually inspected for defects in workmanship and visible contamination.

All product contact surfaces are composed of polytetrafluoroethylene or polypropylene. Both polymers are chemically inert and have a high degree of compatibility with a variety of fluids.
As with other processing aids, the user, who is most knowledgeable about the formulation of the product, is responsible for ensuring the compatibility of their formulation with GORE LYOGUARD Trays.
The GORE LYOGUARD Tray may be steam sterilized once (if necessary), using a moist heat, pre-vacuum autoclave cycle. Refer to GORE LYOGUARD Freeze-Drying Trays Validation Guide for more information.
