Glass Flasks

Flasks come in a variety of shapes and sizes and a specified volume measured in metric units such as milliliters (mL) or liters (L). We offer Erlenmeyer, Buchner, and Volumetric Flasks manufactured from the highest quality materials for use in the lab. Laboratory flasks have traditionally been made of glass, but they are also available in plastic-coated-glass varieties.

At the opening at top of round-bottom flasks and volumetric flasks, there are often outer tapered joints. Some flasks, especially volumetric flasks, come with a stopper or cap made of glass, plastic or Teflon®. Flasks which do not come with stoppers may be capped with a rubber bung or cork stopper. (Appropriate bung sizes are noted on each product page.)

Flasks are ideal for volumetrically measuring chemicals, samples, and solutions for chemical reactions or other processes such as mixing, heating, cooling, dissolving, precipitation, distillation, or analysis.
