Density Testing Flasks
 |
Accurately measure the density of a liquid based on volume and weight. Also known as pycnometers, these flasks help you compare the specific gravity of a liquid to water. They’re often used for quality control in labs for food and beverage, pharmaceutical, or chemical manufacturing. Made from borosilicate glass, these flasks resist chemicals and won’t expand or contract from temperature changes. Use the included non-mercury thermometer to check the temperature of your sample—it's tested for accuracy, has small increments for precision, and is safe for shipping and handling. You can place these flasks in a constant temperature bath to control the temperature of the liquids inside.
To find the specific gravity of a liquid, divide the weight of the testing liquid by the weight of water at the same temperature.
50 ml Capacity—50 ml flasks help you comply with ASTM D153 testing standards for finding the specific gravity of pigments.
