Qorpak Bottle Beakers® also known as Graduated Medium Rounds are excellent for use with biological and pathological specimens, but can also be used for storing industrial laboratory chemicals and reagents. These clear / flint bottles are designed with a slight shoulder for easy pouring and handling. Graduated in ml and ounces. Mix, measure, and store in the same container.
Attached black thermoset (phenolic) caps with solid PE liners offer good chemical resistance and low moisture vapor transmission rate. They are great for nail polish remover and higher concentration acids & alkalis. Good for non-oil products filled at room temperature. Because this lining system is paperless, your samples will not be contaminated with fiber or paper particles from the closure.
