Recommended for specimens over 12" in length (dogfish, cats). This polyethylene tray is chemical-resistant and lightweight. The 16" x 30" tray holds a 10" x 23" Flex-Pad allowing for easy pinning and cleanup. Corner pegs are included for tying specimen to tray. Replacement Flex-Pads and a clear plastic cover are available separately. The cover will help to prevent drying out of the specimen between lab periods.
