Lab Supply - Glass Flasks


March 2015

SKS Science offers a wide range of glass flasks from Erlenmeyer to volumetric in sizes ranging from 5 ml to 6,000 ml. Laboratory glassware is often times a better choice when compared to plastic, due to its strong resistance to heat and chemical attack. All SKS Science glass flasks are made of KIMAX® borosilicate glass. The chemical compound of borosilicate glass makes it stronger than most other forms. It has a high resistance to temperature change, is very durable and has a maximum working temperature of 515 degrees Fahrenheit.

The KIMAX® glass Erlenmeyer flasks come in two different styles, narrow mouth and wide mouth. The difference between the two being that the narrow mouth flask has a smaller neck and opening than the wide mouth flask. The narrow mouth Erlenmeyer flask comes in sizes ranging from 25ml to 6,000ml while the wide mouth Erlenmeyer flasks are offered in sizes ranging from 125ml to 2,000ml. Both conform to USP Type I and ASTM E438, Type I, Class A requirements. Each size has a capacity scale as well as a marking spot for labeling, and both flasks have a beaded lip to offer more mechanical strength. The shape of an Erlenmeyer flask is meant to avoid spilling when mixing the contents by swirling, making them a great option for titrations.
