Test Tubes, Round Bottom, Plain

These chemically clean test tubes are normally used in labs for mixing and experimentation purposes. Each tube is annealed at temperatures over 426.7°C (800°F) to increase strength and reduce breakage. Tubes feature smooth, well-rounded bottoms with no irregularities. Tops are fire polished to eliminate rough edges. Formed from 7.0 expansion borosilicate glass tubing to reduce pH changes and contaminants potentially leached from soda lime glass tubing.
