Conical flask with a wide throat

Wide Mouth Access for Simplified Sample Handling

You're preparing a microbial culture at 2 AM when your spatula slips and agar powder scatters across the bench. With a standard narrow-neck flask, you'd be fishing out clumps with tweezers for the next ten minutes. A conical flask with wide throat changes that scenario entirely—the enlarged opening lets you pour, scoop, and scrape without the bottleneck frustration that plagues routine prep work.

Working with borosilicate 3.3 glass construction, these flasks handle thermal shock from -70°C to +500°C while the reinforced rim survives countless autoclave cycles. Graduated markings run up the conical body, giving you visual confirmation without stopping your workflow to check volumes.

Easy Addition of Solid Reagents

Powder transfers become straightforward when the throat diameter opens 20-50% wider than conventional designs. Agar, salts, and buffer compounds pour cleanly without bridging at the neck. Large spatulas fit through without scraping glass, and you can insert pH probes or thermometers while mixing proceeds. Compare this to round bottom flask designs where narrow necks force you to use funnels for every addition, or flat bottom flask options that lack the self-centering vortex action during magnetic stirring.

Cleaning and Maintenance Advantages

• Brushes reach every interior surface without contorting through tight openings
• Visual inspection catches residue that narrow necks hide in shadow
• Dishwasher spray jets penetrate fully for automated cleaning cycles
• Your hand actually fits inside smaller volumes for manual scrubbing when needed

Unlike round-bottom flask with socket configurations that require specialized brush angles, the wide throat pairs with standard cleaning tools you already stock.

Media Preparation and Culture Applications

Cell culture media mixing demands repeated ingredient additions—yeast extract, peptones, supplements that arrive as chunky powders. The wide opening accommodates serological pipettes up to 50ml without tilting the flask at awkward angles. When scaling up from laboratory boiling flasks or transitioning from flat bottom flask with socket setups, the conical geometry maintains efficient heat distribution while the throat diameter prevents the ingredient-addition delays that bottleneck your prep schedule.
