SEPARATE LIQUIDS WITH PRECISION: Purer extractions lead to more accurate work. Precisely separate compounds using the graduated lab funnel and the leak-proof PTFE stopcock. This graduated container is designed for solvent/liquid-liquid extraction and is an essential tool in any lab. We recommend you run an extraction at least 2-3 times for the best results (distillation may be needed to remove impurities).
CONSTRUCTED TO LAB AND INDUSTRIAL STANDARDS: The Fristaden Lab Separatory Funnel can handle tough, corrosive materials and high and low temperatures without breaking. The separating funnel is made with lab-quality borosilicate beaker 3.3 glass, which can handle much more stress than standard glass. The flask also features a corrosion resistant PTFE stop cock.
PACKED SO IT WON’T BREAK: Our lab filter funnel, encased in sturdy foam packaging, will safely make the journey to your door. Lab equipment with inferior packaging has a high risk of breaking in transit.
BEER BREWING? SAVE MONEY ON YEAST: The separatory funnel is a useful tool for any dedicated brewer. The flask can be used to easily wash previously-used yeast for future use. The separating flask is especially handy for lagers and other bottom-fermenting beers where you can’t easily scrape the yeast. For professional brewers, recycling yeast not only saves money, but also allows you to preserve unique strains of yeast.
