Key Features
- Compact body for small-volume control: the slim tube keeps micro samples close to the scale line during pipetting, dilution, and short observation work.
- Smooth mouth for rack handling: the polished opening feels less rough during loading, rinsing, and stopper matching.
- Clear graduation for quick reading: the fine scale lets operators check small-volume transfers and teaching demonstrations without another measuring vessel.
- Small format for bulk supply: the compact body fits dense rack placement and carton-based supply for labs and distributors.

Quality Control
Production is checked against the approved sample and confirmed 5ml specification before release. For this small tube size, Yukang checks tube straightness, scale clarity, smooth mouth finish, rack handling, and visible glass condition. Pieces with unstable shape or unsafe finish are removed before packing.
