This capillary tube, produced by Canrd with a 0.3 mm inner diameter (model MA-CM-GL-020J1U), is designed for precise liquid handling and sample transfer in laboratory settings. As a general consumable made of glass, it offers chemical inertness and thermal stability suitable for use in chromatography, microinjection, or microscopic analysis. The narrow bore enables controlled capillary action, making it a reliable tool for applications requiring accurate fluid management in small volumes. Its standardized dimensions support compatibility with common experimental setups across materials research, biochemistry, and analytical chemistry. This product serves as a straightforward, functional component for routine laboratory workflows rather than a specialized device.
