We have three sizes of volumetric flasks to choose from: 100, 250 and 500 milliliters and they feature a single etched line or graduation to denote the fill-to-line at the chosen volume. Each size flask is specifically made for preparing solutions that correspond to its nominal value. For example, a 250 ml volumetric flask is the appropriate choice only when preparing a solution with a total volume of 250 ml.
500ml Erlenmeyer Flask. The 500ml erlenmeyer lab flask is large enough to allow mixing and storing of relatively large amounts of various liquids and can be sealed with either a cork or rubber stoppers. These flasks are made from heat resistant borosilicate glass & are autoclaveable. See Related Products below for cork & rubber stoppers that fit this flask.
