The buret is made of acrylic for durability, and has a polytetrafluoroethylene (PTFE) plastic plunger stopcock for resistance to chemicals, moisture, and high temperatures. Acrylic is lightweight, and resists shattering, impact, and most non-abrasive cleaners including ammonia and strong detergents. PTFE plastic is a strong, low-friction material that has smooth transfer, high surface release, and nonstick properties. It has high chemical resistance, and resists moisture, high temperatures, flames, thermal expansion, and ultraviolet (UV) exposure. PTFE has low temperature toughness. The buret has 100.0mL capacity with 0.10mL graduation, and is suitable for high school or college students, or ages 14 to 21.
