PYREX 60° Angle Fluted Laboratory Funnel - Short Stem Borosilicate Glass Funnel – Premium Chemistry Reusable Funnel for Laboratories, Classrooms or Home Use - PYREX Lab Glassware, 75mL, 2/Pk

PYREX 60° Angle Fluted Laboratory Funnel Made from Type 1, Class A low expansion borosilicate glass, PYREX scientific glassware has become the accepted standard in chemistry labs across the globe. These PYREX fluted laboratory funnels have a short stem, and the chemistry funnels are fabricated from blanks formed to a 60° angle which allows accurate filter paper fitting. Designed for use in flasks or test tubes without a filter rack, the lab funnels have depressed inside flutings to further decrease filtering time. The borosilicate glass funnel is suitable for heating many times to 230°C and cooling to -230°C, and the high-quality lab equipment is chemically resistant to most acids, alkalis and solvents, allowing the glass funnel to accommodate harsh materials. Suitable as professional laboratory equipment, the lab glassware is also ideal for home or classroom STEM activities and experiments, and has a strong beaded edge for strength. Easy to clean or sterilize in autoclaves up to 121°C at 15 psi for 15 minutes, this range of PYREX borosilicate glass filters is available in sizes from 50mm – 100mm inside diameter. PYREX scientific glassware - trusted by scientists for 100 years Exceptional strength and stability. Brilliant transparency. Superior resistance to chemicals, contaminants, and drastic changes in temperature. These are among the key properties that enable PYREX glass to endure even the toughest laboratory environments, making it the indispensable partner for chemists and research scientists for more than 100 years.
