Amber narrow-mouth (N/M) reagent bottles with a 60ml capacity are widely manufactured in China for laboratory and pharmaceutical use. These bottles are primarily available in two materials: borosilicate glass (with ground-in stoppers or screw caps) and plastics such as HDPE or PP.
A 60ml Amber Narrow-Mouth (N/M) Reagent Bottle is a specialized laboratory container used for storing and dispensing light-sensitive chemical reagents. The “N/M” designation stands for Narrow Mouth, which is designed to minimize spillage, reduce evaporation, and facilitate controlled pouring of liquids.
Key Features & Specifications
