GrainSense Glassless Tray has been designed in order to enable measurements of larger diameter seeds. Glass of the tray is removed and replaced by a thin Teflon sheet (to protect the bottom sphere glass). The package contains 3 protection Teflon discs. 

This additional space allows fitting whole maize and soybean kernels into the Analyzer.

Please note: Glassless Tray is only compatible with the A-2 version of the GrainSense Analyzer
