| Narrow Neck | 250, 500, 1000 | Borosilicate Glass | Titration and chemical analysis |
| Wide Mouth | 250, 500 | Polypropylene | Mixing and easy pouring |
| Graduated Flasks | 100, 500 | Borosilicate Glass | Accurate measurements and mixing |
| Non-Graduated Flasks | 250, 1000 | Borosilicate Glass | General lab use, heating, and storage |
Types of Conical Flasks
Conical flasks come in various types, each tailored for specific laboratory needs. The primary types include:
Standard Erlenmeyer Flask
These flasks are the most common type found in laboratories. They have a flat base and a tapered neck, making them ideal for swirling without the risk of spillage. They are available in sizes ranging from 100 mL to 2000 mL and are typically made of borosilicate glass, which is known for its excellent thermal resistance.
Baffled Erlenmeyer Flask
Baffled flasks are designed with external ridges or baffles. This design improves mixing efficiency and is particularly useful in biological applications, such as cell culture and fermentation. These flasks are often larger, accommodating volumes from 1000 mL to 2000 mL.
Narrow Neck and Wide Mouth Flasks
Narrow neck flasks are useful for titration and chemical analysis, while wide mouth flasks facilitate easy pouring and mixing. Both types can be made from either glass or polypropylene, depending on the specific needs of the laboratory.
Graduated vs. Non-Graduated Flasks
Graduated flasks feature measurement markings, allowing for precise volume measurements. Non-graduated versions are often used for general purposes where exact measurements are not critical.
Applications of Conical Flasks
Conical flasks play a significant role in various laboratory applications:
Titration
The tapered neck and wide base of the conical flask make it ideal for titration experiments. The design allows for easy swirling of solutions without risk of spillage, ensuring accurate results.
Mixing Solutions
Whether for chemical reactions or preparing solutions, conical flasks offer a secure environment for mixing. The shape allows liquids to swirl and mix thoroughly, which is crucial for many laboratory procedures.
Heating
The borosilicate glass material used in most conical flasks can withstand high temperatures, making them suitable for heating solutions on a hot plate. The ability to seal these flasks with a stopper also allows for controlled heating.
Storage
Conical flasks can be sealed and used for storage of reagents and solutions. Their design helps to minimize contamination risks, making them a preferred choice for long-term storage.
