<h2>Laboratory Flasks for Research and Production</h2>
<p>Laboratory flasks are among the most widely used vessels in scientific research, bioprocessing, and quality-control work. From bench-scale culture experiments to pilot-scale fermentation, flask selection affects mixing efficiency, gas transfer, contamination risk, and workflow reproducibility. mLab Supply sources new, refurbished, and surplus laboratory flasks from established manufacturers to support research institutions, contract development organizations, and industrial laboratories. Configurations and availability vary by format, volume, and material. <a href="/pages/request-a-quote">Contact mLab Supply to request sourcing options</a>.</p>
<h2>Erlenmeyer Flasks</h2>
<p>The Erlenmeyer flask is the standard vessel for liquid culture, mixing, titration, and sample preparation across virtually every laboratory discipline. Its conical body and narrow neck reduce evaporation and minimize splash during agitation, making it well suited for orbital shaker work, microbial culture, and reagent preparation. Erlenmeyer flasks are available in borosilicate glass and a range of polymer materials including PETG and polycarbonate, in volumes from small benchtop sizes up to several liters. mLab Supply sources Erlenmeyer flasks from multiple manufacturers and can assist with volume sourcing for active research programs.</p>
<h2>Baffled Erlenmeyer Flasks</h2>
<p>Baffled Erlenmeyer flasks incorporate raised ridges or indentations along the interior wall that disrupt laminar flow during orbital shaking. This design significantly increases oxygen transfer and mixing efficiency compared to smooth-walled flasks at equivalent shaker speeds, making baffled formats the preferred choice for aerobic microbial culture, yeast fermentation studies, and enzyme production workflows. Corning and other suppliers offer baffled Erlenmeyer designs in standard volumes compatible with common shaker platforms. Availability and baffle geometry vary by manufacturer and model. <a href="/pages/request-a-quote">Request a quote</a> for baffled flask sourcing.</p>
<h2>Fernbach and Shake Flasks</h2>
<p>Fernbach flasks offer a wide, shallow body relative to their volume, providing a larger liquid surface area than a conventional Erlenmeyer flask of equal capacity. This geometry supports improved gas exchange and is commonly used in high-density microbial culture, fungal fermentation, and scale-up work where oxygen availability is a limiting factor. Shake-flask culture using Fernbach vessels is a standard bridging step between microplate-scale screening and bioreactor-scale production. Thermo Scientific Nalgene offers polycarbonate Fernbach flasks suited to autoclave-compatible workflows. Contact mLab Supply for current sourcing availability.</p>
<h2>Choosing the Right Flask Format</h2>
<p>Flask selection should reflect the specific demands of the application. Key considerations include required working volume and headspace ratio, whether agitation will be used and at what speed, the importance of oxygen transfer rate to the biological system, closure compatibility with cap or membrane vent requirements, and whether autoclave sterilization or single-use disposable options are appropriate. Baffled formats are generally preferred for aerobic cultures requiring high dissolved oxygen; smooth-walled Erlenmeyer flasks remain the standard for most general mixing and culture work; Fernbach formats are selected when surface-area-to-volume ratio is the primary design constraint.</p>
<h2>Glass vs. Plastic Flask Considerations</h2>
<p>Borosilicate glass flasks such as those in the DWK Life Sciences DURAN line offer chemical resistance, optical clarity, and reusability with standard autoclave sterilization protocols, making them suitable for applications requiring solvent contact or long-term reagent storage. Plastic flasks in materials such as polycarbonate, PETG, and polypropylene offer lighter weight, reduced breakage risk, and in some cases single-use convenience, and are widely used in cell culture and fermentation scale-up workflows. Material compatibility with media, solvents, and sterilization methods should be confirmed prior to use. mLab Supply can assist with sourcing specific materials and closures based on application requirements.</p>
<h2>Common Laboratory Applications</h2>
<p>Laboratory flasks are used across a broad range of scientific workflows including microbial culture and fermentation, mammalian and insect cell culture scale-up, enzyme and metabolite production, reagent and buffer preparation, chemical synthesis and titration, seed train preparation for bioreactor inoculation, and quality-control sample handling. The appropriate flask format, volume, and material depend on the specific biological system, shaker compatibility, and downstream processing steps involved in each application.</p>
<h2>Flask Manufacturers</h2>
