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. Review: Cream of the crop - This is a high-quality product that performs exceptionally well in a variety of laboratory settings. There were no defects or imperfections, and the flask handled extreme temperature changes with ease, providing reliable and consistent results. Its durable construction and precise design make it a dependable choice for anyone needing a robust, versatile flask for scientific work. I highly recommend this flask to anyone in need of a top-tier laboratory tool. Review: Not just for labs! - I have several sets of these and use them for a lot of stuff, none in a science lab or classroom. Unless you count my kitchen as a science lab. They (with cork stoppers) currently hold water, taco sauce from a taco kit, and homemade salad dressing in the fridge, M&Ms, peanuts and almonds on my counter, and flowers in my living room. The tiny one makes a really cute bud vase. With my soapstone countertop and these and beakers holding various foods, I guess I do kind of have a Breaking Bad kitchen! These are good quality and fun to have around. ## Features - 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. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B005MIPIWK | | Best Sellers Rank | 313,615 in Business, Industry & Science ( See Top 100 in Business, Industry & Science ) 455 in Lab Flasks | | Bottom Shape | Round | | Bottom shape | Round | | Brand | Pyrex | | Capacity | 50 Millilitres | | Customer Reviews | 4.9 out of 5 stars 31 Reviews | | Item Weight | 2.4 Pounds | | Manufacturer | Glass Corning Incorporated, Life Sciences | | Manufacturer Part Number | 4980-PACK | | Material | Borosilicate Glass | | Material Type | Borosilicate Glass | | Model Number | 4980-PACK | ## Product Details - **Bottom shape:** Round - **Brand:** Pyrex - **Capacity:** 50 Millilitres - **Manufacturer:** Glass Corning Incorporated, Life Sciences - **Material:** Borosilicate Glass ## Images ![PYREX Narrow Mouth Erlenmeyer Flask with Heavy Duty Rim,Borosilicate Glass Flask – Premium Glass Chemistry Flask for Laboratory, Classroom or Home Use,PYREX Chemistry Glassware, Multipack, Set of 5 - Image 1](https://m.media-amazon.com/images/I/51G7gA2ktBL.jpg) ![PYREX Narrow Mouth Erlenmeyer Flask with Heavy Duty Rim,Borosilicate Glass Flask – Premium Glass Chemistry Flask for Laboratory, Classroom or Home Use,PYREX Chemistry Glassware, Multipack, Set of 5 - Image 2](https://m.media-amazon.com/images/I/61PNb+dl4yL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Cream of the crop *by T***K on 8 November 2024* This is a high-quality product that performs exceptionally well in a variety of laboratory settings.

Its durable construction and precise design make it a dependable choice for anyone needing a robust, versatile flask for scientific work. I highly recommend this flask to anyone in need of a top-tier laboratory tool. ### ⭐⭐⭐⭐⭐ Not just for labs! *by H***N on 2 June 2017* I have several sets of these and use them for a lot of stuff, none in a science lab or classroom. Unless you count my kitchen as a science lab. They (with cork stoppers) currently hold water, taco sauce from a taco kit, and homemade salad dressing in the fridge, M&Ms, peanuts and almonds on my counter, and flowers in my living room. The tiny one makes a really cute bud vase. With my soapstone countertop and these and beakers holding various foods, I guess I do kind of have a Breaking Bad kitchen! These are good quality and fun to have around. ### ⭐⭐⭐⭐⭐ Precision measurement *by V***Z on 13 April 2016* This starter pack can be put to use by any novice or expert alike. With pinpoint measurements from 50mL to 1000mL, these little guys truly pack a punch when precision is required. The durability of Pyrex is also a huge selling point, as they are pretty well shatter resistant. After transferring my pack from room to room, one fell out of my grasp and landed flat on concrete from five feet. Expecting an explosion of glass, to my amazement there it bounced and landed flat with no issue.
