Product Overview
50ml Glass Test Tube is a medium-volume glass tube for labs that need more space than a routine small test tube provides. It is used for chemical synthesis, biological cultivation, batch sample detection, storage, and reaction observation when the 50ml working volume should stay in one tube during preparation and checking.

Key Features
- Medium-volume handling: the wider body holds larger sample preparation, reaction observation, and batch testing work without repeated subpackaging.
- Thickened wall for daily use: the wider tube has better resistance to bench contact, rack movement, washing, and repeated lab handling.
- Scale reading for dosage checks: the interval scale keeps sample volume visible when several tubes are filled together.
- Stopper fit for temporary covering: the mouth matches common stopper sizes for short-term holding, display, and transfer inside the lab.

- Diameter and Length: standard fixed-volume formats plus non-standard tube development
- Wall Thickness: standard wall range plus stronger wall options for bulk supply

Quality Control
50ml Glass Test Tube inspection checks capacity accuracy, wall strength, mouth finish, and stopper matching. Yukang confirms the approved sample, tube size, capacity reference, wall thickness, scale position, and stopper specification before production. The batch is then checked for capacity consistency, diameter, length, wall uniformity, transparency, cracks, bubbles, scratches, mouth smoothness, and stopper fit.
Products that do not match the approved sample are removed before shipment preparation. Yukang checks every tube before packing, accepts third-party inspection, and handles confirmed quality issues through the 3-year warranty.
