MTC™ Bio Erlenmeyer Flasks

Sterile, Vented, High-Performance Cell Culture Flasks.

MTC™ Bio’s Erlenmeyer Shaker Flasks are designed for high-efficiency cell culture and microbial growth. Made from high-quality polycarbonate, PETG, or styrene/butadiene (for Jumbo Flasks), these flasks provide durability and clarity for optimal lab performance.

Each flask features a vented polypropylene screw cap with a 0.2 uM membrane filter, allowing enhanced gas exchange to support vigorous cell growth. The standard SBS-compatible mouth ensures a secure fit with bioreactor and shaker equipment for seamless integration.

Polycarbonate flasks and Jumbo Fernbach flasks feature a baffled (ribbed) bottom, promoting superior oxygenation and efficient mixing, even at lower shaking speeds.

All Erlenmeyer flasks are individually wrapped and gamma sterilized to a Sterility Assurance Level (SAL) of 10, and are certified RNase-, DNase-, pyrogen-, endotoxin-, and human DNA-free for uncompromised experimental conditions.

Key Features

• Vented screw caps with 0.2 uM filters for increased air exchange
• Available with flat or baffled bottoms
• Gamma sterilized (SAL 10)
• Free of RNase, DNase, pyrogens, endotoxins, and human DNA
• Individually wrapped for sterility
• Polycarbonate flasks are autoclavable at 121°C and 15 psi for 30 minutes 

These flasks are ideal for suspension cell cultures, microbial fermentation, and other bioreactor-compatible applications.
 

NEST High-Efficiency Erlenmeyer Flasks

High-efficiency, large-volume culture flasks allow cells to show strong viability with large expression amounts of proteins in the culture of mammalian cells and insect cells. During the culturing process, the use rate of the shaker is significantly increased, and the survival rate and viability of cells are both dramatically elevated.

NEST culture flasks also provide high repeatability, which allows high inter-batch consistency of cell growth and yield.

3 L Wide-mouth Efficient Erlenmeyer Flask

• Borosilicate 3.3 hybex™ glass
• Autoclavable, reusable & breakage resistant
• Permanent enamel graduation markings
• Ideal for shaking, media prep or storage

hybex™ Erlenmeyer Flasks are manufactured from high quality, borosilicate 3.3 glass. A low coefficient of thermal expansion (3.3), provides temperature resistance that is far superior to that of standard lab glass (or soda lime glass). hybex™ glass is designed to withstand high temperatures, making them ideal for shaking applications, media preparation and long-term storage.
The standard Erlenmeyer flasks have permanent, white enamel graduations for volume measurement and a white identification box for marking or coding.

hybex™ Erlenmeyer Flasks with GL45 caps
 
For storage of media and cultures, the capped flasks include an autoclavable polypropylene cap & drip-ring. Optional cap colors are available, as well as PBT material caps for temperature applications up to 180°C. (Threads are standard GL-45 for compatibility with a wide range of cap types from various manufacturers, including phenoic caps, vented caps, etc.)

Heathrow Scientific® Lead Rings

Heathrow Scientific® Lead Rings are designed to stabilize glassware and lab vessels securely on the benchtop or in water baths. These vinyl-coated lead rings offer a flexible and protective solution for preventing tipping or movement of flasks, beakers, and cylinders during procedures.

The durable vinyl coating protects both your labware and benchtop from scratches, marks, or damage, while the C-shape design option allows for slight manual adjustment to accommodate a range of vessel sizes.

Ideal for labs using water baths or uneven surfaces, these stabilizing rings improve safety and efficiency during experiments. Sold in vibrant blue, they offer easy visibility in busy workspaces.

Key Features

• Stabilizes labware on benchtops or in water baths
• Vinyl-coated lead won’t scratch glassware or lab surfaces
• Ideal for use with flasks, beakers, and graduated cylinders
• Durable, reusable, and easy to clean
• Color: Blue for visibility and organization

Sterile 250mL polycarbonate flask without baffles. Virtually unbreakable Lexan (registered trademark of GE Plastics) polycarbonate is used in the manufacture of this product.

Flask comes sterile via gamma irradiation, packaged in its own protective bag with two polypropylene 38mm closures. One is a standard leakproof closure. The other is a vented closure with a PTFE membrane, 0.22um pore size for sterile air exchange.

The polycarbonate is autoclavable which makes for repeated reuse of the flasks. They are certified non pyrogenic and DNase/RNase free for convenience. Product fits all standard shaking incubator slamps and are ideal for culture, media preparation, storage and any related application.
