BulkSeal™ Tray

BulkSeal™ Freeze Drying Tray

Aseptic and Anaerobic for Bulk Lyophilization Applications

The BulkSeal Tray is a sealable bulk tray system for anaerobic, sterile, or aseptic applications. It is impermeable and can handle liquids, solids, and devices. The tray eliminates the risk of particle generation, enables transport and storage, and protects its operators.

Compared to a single-use enclosed freeze drying tray, the BulkSeal Tray is reusable, providing a sustainable option for your application. Our tray can also be fitted with a transparent lid enabling visual inspection and can seal other devices under vacuum, such as well plates, diagnostic beads, tissue and other custom container types not suitable for single-use enclosed freeze drying trays.
