In China, 1000ml wide-mouth (W/M) reagent bottles are a staple lab supply produced by numerous manufacturers such as Jiangsu Huida Instruments and Yancheng Rongtai Labware. These bottles are specifically designed for storing solid reagents, powders, or viscous liquids due to their large-diameter neck, which allows for easy access with spatulas or scoops.
