Profesional manufacturer & supplier for test equipment & analytical instruments since 2003.
PTFE Volumetric Flask
Note: Due to the opaque characteristics of the material itself, the liquid level cannot be seen when the volume is fixed. If the requirements for experimental data are higher, it is recommended to use a volumetric flask made of FEP material.
Features
1. Pure white appearance, good sealing.
2. High and low temperature resistance, usable temperature -200℃～+250℃.
3. The upper port is a sealing plug, and the lower port can be used as standard ports such as 19 and 24 ports.
4. Corrosion resistance, strong acid, strong alkali, aqua regia and various organic solvents, and no dissolution, adsorption and precipitation.
5. Anti-pollution, low blank value of metal elements.
6. Resistance to atmospheric aging, radiation resistance and low permeability.
7. Self-lubricating and low surface viscosity, soft texture, smaller friction coefficient and smaller surface energy
8. Harmless: with physiological inertia.
