Product Spotlight - Glass and Plastic Erlenmeyer Flasks

Durable glass wide mouth and narrow mouth Erlenmeyer flasks feature a wide range of capacity choices, heavy-duty tooled top finish, matte white ceramic writing areas, and graduations, making them versatile for a range of laboratory processes. The wide mouth and narrow mouth Erlenmeyer flasks reach ASTM Specification E1404, Type I, Class 1 (narrow) or Class 2 (wide) requirements.

SKS Science offers the clear glass narrow mouth Erlenmeyer flasks in a convenient starter pack with five different sizes, ranging from 50 ml to 1,000 ml capacities.

Wheaton offers two non-graduated Erlenmeyer flasks that feature white writing areas and optional use with compatible closures. 1,000 ml clear glass Erlenmeyer flasks are designed for biological or media culture storage. These lab flasks are paired with black caps that feature an ultrasonically bonded silicone liner, which eliminates the possibility of contamination from adhesives. These Erlenmeyer flasks are composed of 33 low extractable borosilicate glass, meeting ASTM Type 1 Class A and USP Type 1 standards, and can be autoclaved between uses.

Clear glass 25 ml Erlenmeyer flasks are highly popular for continuous extraction of analytes from a solid into an organic solvent. The specialized threaded neck of these Erlenmeyer flasks makes them compatible with black phenolic LDPE cone lined caps, which are sold separately.

Plastic Erlenmeyer flasks can be an economical choice when a heating process is not necessary. Polycarbonate Erlenmeyer flasks paired with blue polypropylene closures are available in a wide range of capacities and are composed of unbreakable Lexan polycarbonate. These plastic Erlenmeyer flasks come with or without baffles, which assist with regulating the flow of liquid within the flasks.

The Erlenmeyer flasks are shipped via sterile via gamma irradiation and packaged in a protective bag. Matched with each Erlenmeyer flask are two blue polypropylene caps, one being a standard leak proof closure, and the second a vented closure with a PTFE membrane, which has a 0.22 um pore size for sterile air exchange. These Erlenmeyer flasks can be autoclaved for repeated use and are certified non-pyrogenic and DNase/RNase free.

SKS Science offers Erlenmeyer flasks composed of autoclavable polypropylene in a selection of styles and sizes that are durable and chemically resistant. Natural narrow mouth Erlenmeyer flasks include molded graduations and are constructed from one piece of plastic to eliminate any weak points. These lab flasks are a top choice for long term use with minimal degradation. Natural wide mouth Erlenmeyer flasks with blue printed graduations come in capacities ranging from 50 ml up to 1,000 ml and are sold with compatible natural polypropylene threaded closures. Printed next to the blue graduations, the Erlenmeyer flasks include the maximum temperature of polypropylene, the polypropylene recycle code, and the do not heat universal symbol.

Natural polypropylene Erlenmeyer flasks with tooled necks match with polypropylene stoppers and are available in capacities from 50 ml to 1,000 ml. Graduations, maximum temperatures, and the universal do not heat symbol are printed on the Erlenmeyer flasks in permanent black ink.
