In the world of scientific research and laboratory work, professionals use countless tools and equipment daily. One of these indispensable tools is the Falcon tube. If you’re not familiar with what a Falcon tube is or how it’s used, you’re in the right place. This guide will explain everything you need to know about Falcon tubes.
What is a Falcon Tube?
Falcon tubes, a type of plastic tube commonly used in laboratories for various scientific purposes, especially in biology and chemistry, are named after the Falcon brand, which originally produced them, but the term “Falcon tube” has become a generic name used to describe similar types of tubes from various manufacturers.
Manufacturers typically make Falcon tube of high-quality plastic, such as polypropylene or polystyrene, and produce them in various sizes, ranging from small tubes that hold just a few milliliters to larger tubes that can hold up to 50 milliliters or more. Falcon tubes are known for their durability, clarity, and the ability to withstand high speeds in centrifuges (machines that spin samples at high speeds).
Why are Falcon Tube Important in Laboratories?
Falcon tubes are essential in laboratories for several reasons: –
- Researchers commonly use Falcon tube to store liquid samples such as cell cultures, chemicals, or biological specimens, ensuring that their secure caps keep the contents uncontaminated and safe during storage.
- Falcon tubes are designed to withstand the high forces generated during centrifugation, a common technique used to separate substances in a mixture based on density, making them ideal for separating components of blood, purifying DNA, or isolating proteins.
- Researchers also use these tubes to transport samples from one location to another, ensuring that their robust construction keeps the samples intact during transit.
- Falcon tubes are easy to label and mark, aiding in identifying samples quickly and accurately. They are also user-friendly, featuring flat caps for easy labeling and clear graduations for precise measurement.
Types of Falcon Tube
Falcon tubes come in several different types, each designed for specific applications:
- Conical Tubes: These tubes have a conical shape, with a wider top that tapers down to a narrow bottom, making them especially useful during centrifugation for the easy collection of precipitates at the bottom. –
- Round-Bottom Tubes: These tubes have a rounded bottom and are generally used for gentle mixing or storing liquid samples.
- Flat-Bottom Tubes: These tubes are designed to stand upright on flat surfaces, making them ideal for storage and handling without the need for a separate tube rack.
- Graduated Tubes: Many Falcon tubes have graduations (markings) along the side to help measure the volume of the liquid inside accurately, which is particularly important in experiments where precise measurements are crucial.
Sizes and Capacities
Falcon tubes come in various sizes and capacities to suit different needs:
- 15 mL Falcon Tubes: These are smaller tubes, often used for smaller sample volumes. They are perfect for tasks like aliquoting small amounts of liquids, storing small sample volumes, or performing centrifugation with limited sample sizes.
- 50 mL Falcon Tubes: These larger tubes are more commonly used for storing or centrifuging larger sample volumes. They are often used in experiments that require mixing larger quantities of liquids or separating larger sample volumes through centrifugation.
How to Use Falcon Tubes
- Label the Tube: Before adding any sample to the Falcon tube, label it clearly with relevant information such as sample type, date, and any other necessary details to keep track of samples and avoid mix-ups.
- Add the Sample: Carefully add your sample to the tube using a pipette or other appropriate tool. Ensure that the volume does not exceed the tube’s capacity.
- Seal the Tube: Once the sample is inside, securely close the cap to prevent any leakage or contamination.
- Centrifugation (if needed): If you need to centrifuge the sample, place the tube in a centrifuge machine. Ensure that the centrifuge is balanced by placing tubes of equal weight opposite each other. 5. Storage: After processing, store the sample in the Falcon tube at the appropriate temperature for the sample type.
Common Applications of Falcon Tubes
Falcon tubes are versatile and used in a wide range of scientific applications:
- Cell Culture: In biology, Falcon tube are often used for growing and maintaining cell cultures, providing a sterile environment for cells to grow.
- Molecular Biology: These tubes are used in processes like DNA extraction, where samples need to be mixed, centrifuged, and stored.
- Biochemistry: In biochemistry labs, Falcon tubes are essential for mixing chemicals, preparing solutions, and performing various experimental procedures.
- Clinical Laboratories: Falcon tube are widely used in medical labs for handling blood samples, urine, and other biological specimens.
Tips for Proper Falcon Tube Handling
- To prevent spillage and ensure proper mixing or centrifugation, avoid overfilling the tubes.
- Keep tubes organized and prevent them from tipping over by using appropriate tube racks.
- Maintain sterility and avoid contamination by handling Falcon tubes with clean gloves.
- Ensure sample integrity by storing tubes in a sterile environment.
- Prevent reactions or degradation by checking the tube material’s compatibility before using with chemicals or solvents.
