Specifications/Salient Requirements
GlutoPeak
Background and Scope
The Agriculture Research Service (ARS) has a requirement for the purchase of a GlutoPeak instrument that rapidly (1‐10 minutes/sample) measures gluten quality/rheological properties in wheat flour and wheat meal using a 3‐10 g sample. Instrument must include measuring bowl (qty 2) and mixing paddle (qty 2), refrigerated/heating circulator, computer, and software required for operation.
