Pyrex® brand Erlenmeyer flask. High standard series 4980.
This 500ml Pyrex Erlenmeyer flask features a heavy duty rim for longer lab service and approximate graduations in durable white enamel. It also has an extra large marking area.
The Erlenmeyer Flask is used to heat and store liquids. The advantage to the Erlenmeyer Flask is that the bottom is wider than the top so it will heat quicker because of the greater surface area exposed to the heat.
