Pack of 6 Gratnells Trays. The iconic, Worlddidac award-winning Gratnells school tray is found in learning environments all over the world. Made from fully recyclable polypropylene, it is molded to a standardized size for seamless fusion with standard school furniture. The strong rigid tray, which is loved by teachers and technicians is BSI approved for heavy educational use. The talc filled polypropylene makes our tray chemically resistant to more chemicals than other similar storage trays on the market made from ABS. This feature, in addition to it being semi fire-retardant at 0.22mm per minute, makes the Gratnells tray perfect carrying out science activities safely and has made it a staple item in many laboratories and prep rooms over the past 50 years. It even has the added benefit of an anti-static additive in the polypropylene to reduce the attraction of dust. The ease with which the tray can be moved around a learning space and swapped in or out of standardized units cannot be understated. It was designed to help provide a flexible, high-density storage solution on a small footprint, allowing more space to be kept available for learning activities. The tray comes in a range of colors for visually stimulating, color-coded storage and is easily accessible to learners due to its trademarked shape of design. Whether it is chemicals, worksheets, stationery, or robotics kits that need housing, a Gratnells tray is the solution.
