PYREX Narrow Mouth Erlenmeyer Flask with Heavy Duty Rim - Borosilicate Glass Flask – Premium Glass Chemistry Flask for Laboratory, Classroom or Home

LABORATORY FLASK: This narrow mouth conical borosilicate glass flask is ideal chemistry glassware for use in laboratories, schools, and for home and STEM activities and experiments. SAFE & DURABLE: Offering superior heat, chemical and thermal shock resistance, the flat bottom lab glassware with heavy duty rim delivers premium strength and will not shatter easily. CLEAR METRIC MARKINGS: A graduated metric scale in white enamel makes it easy to measure liquids and approximate contents, and the lab glass flask has a large labelling area. EASY TO CLEAN: The reusable glass scientific flasks are easy to clean and can be sterilized safely in autoclaves at 121°C, making them ideal for repeated use in busy lab environments. PYREX GLASSWARE: PYREX scientific glassware has been a trusted partner for chemists and research scientists in the toughest laboratory environments for more than 100 years. PYREX Narrow Mouth Erlenmeyer Flask Made from Type 1, Class A low expansion borosilicate glass, PYREX scientific glassware has become the accepted standard in chemistry labs across the globe. This glass chemistry flask is manufactured with a cylindrical neck, conical body and flat bottom, along with a uniform wall thickness to make it ideal for heating by hot plate, flame, oven, microwave or heating mantles. The laboratory flask’s construction offers optimum balance between thermal shock resistance and mechanical strength, and in normal service it can be heated many times to 230°C and cooled to -230°C. The borosilicate glass flask is chemically resistant to most acids, alkalis and solvents, and the heavy-duty rim reduces cracking or chipping. The ideal chemical and heat resistant chemistry glassware for use in laboratories or for home or classroom science experiments, this range of PYREX low expansion borosilicate glass flasks is available in sizes from 50mL - 1L capacity. The lab glass flasks have approximate graduations marked in durable white enamel, and an extra-large marking spot. These scientific flasks are easy to clean or sterilize in autoclaves up to 121°C at 15 psi for 15 minutes. 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.
