What are the common sizes of lab flasks available?
Lab flasks come in various sizes, ranging from small capacities of 25 ml to larger sizes of 5 liters or more. The choice of size depends on the specific experimental requirements.
Can plastic lab flasks be used for high-temperature applications?
Plastic lab flasks are generally not recommended for high-temperature applications as they have lower heat resistance compared to glass flasks. Glass flasks are better suited for heating or boiling liquids.
Are lab flasks suitable for storing chemicals?
Yes, lab flasks are commonly used for storing chemicals. However, it's important to consider the compatibility of the flask material with the specific chemicals being stored. Glass flasks are typically preferred for chemical storage due to their chemical resistance.
Can lab flasks be used for vacuum filtration?
Certain types of lab flasks, such as filtering flasks or Buchner flasks, are specially designed for vacuum filtration. These flasks feature a sidearm for connecting to a vacuum source, enabling efficient filtration of liquids.
Do lab flasks have any volume calibration markings?
Some lab flasks come with volume calibration markings, particularly volumetric flasks. These markings allow for precise measurement and preparation of solutions with accurate concentrations.
How should I clean lab flasks?
To clean lab flasks, rinse them with suitable cleaning agents and warm water to remove any residue. You can also use a bottle brush or other cleaning tools to reach the inner surfaces. Ensure thorough rinsing and drying before reuse.
Are lab flasks fragile and prone to breakage?
While lab flasks are generally made of sturdy materials like glass or plastic, they should be handled with care to avoid accidental breakage. Avoid strong impacts, rapid temperature changes, and improper handling to prolong their lifespan.
Can lab flasks be used for distillation processes?
Yes, some types of lab flasks, such as round bottom flasks, are commonly used for distillation processes. These flasks can withstand heating under reflux and effectively condense vapors during the distillation process.
