Microcentrifuge Tube

What is a Microcentrifuge Tube?

A microcentrifuge tube, also known as a microtube or microfuge tube, is a small, cylindrical tube used for holding and centrifuging small volumes of liquid, typically in the range of 0.2 to 2.0 milliliters. Microcentrifuge tubes are made of plastic or glass and are commonly used in laboratories for a wide variety of applications, including the separation of cells, subcellular organelles, or molecules; the storage of samples; and the preparation of solutions. They are typically placed in a microcentrifuge, a small, high-speed centrifuge that is used to spin the tubes at high speeds in order to separate or purify the contents.

1.5 ml Microcentrifuge Tubes

A 1.5 mL microcentrifuge tube is a type of small, cylindrical tube with a capacity of 1.5 milliliters (mL). It is made of plastic or glass and is commonly used in laboratories for a variety of applications, including the separation of cells, subcellular organelles, or molecules; the storage of samples; and the preparation of solutions. These tubes are small enough to be placed in a microcentrifuge, a small, high-speed centrifuge that is used to spin the tubes at high speeds in order to separate or purify the contents. 1.5 mL microcentrifuge tubes are often used when working with smaller volumes of liquid, as they allow for more precise measurement and handling. They are also convenient for storing and transporting samples, as they are lightweight and can be easily sealed with a cap or closure.

Microcentrifuge Tubes with Snap Cap

A microcentrifuge tube with a snap cap is a small, cylindrical tube used for holding and centrifuging small volumes of liquid, typically in the range of 0.2 to 2.0 milliliters. It has a cap or closure that is designed to snap securely onto the top of the tube, providing a leak-proof seal. This type of microcentrifuge tube is commonly used in laboratories for a wide variety of applications, including the separation of cells, subcellular organelles, or molecules; the storage of samples; and the preparation of solutions. The snap cap allows the tube to be easily opened and closed, and also helps to prevent spills and contamination. Snap cap microcentrifuge tubes are typically made of plastic, and are small enough to be placed in a microcentrifuge, a small, high-speed centrifuge that is used to spin the tubes at high speeds in order to separate or purify the contents.

Microcentrifuge Tube Rack

A microcentrifuge tube rack is a device used to hold and organize microcentrifuge tubes in a laboratory setting. It is typically made of plastic or metal, and consists of a series of slots or wells in which the tubes can be placed. The rack is designed to hold a specific number of tubes, typically between 6 and 96, depending on the size and design of the rack. Microcentrifuge tube racks are commonly used to hold and store tubes in a laboratory, as well as to transport tubes from one location to another. They are often used in conjunction with a microcentrifuge, a small, high-speed centrifuge that is used to spin the tubes at high speeds in order to separate or purify the contents. The racks are usually designed to fit inside the centrifuge, making it easy to load and unload the tubes. Some microcentrifuge tube racks are also designed with a flat base, allowing them to be placed on a benchtop or other surface for storage or handling.  

Microcentrifuge Tube Uses

  There are many ways in which microcentrifuge tubes can be used in a laboratory setting. Here are a few examples:

  1. Separation of cells or subcellular organelles: Microcentrifuge tubes can be used to separate cells or subcellular organelles from a sample by centrifuging the sample at high speeds. This process can be used to isolate specific types of cells or organelles for further analysis or experimentation.
  2. Preparation of solutions: Microcentrifuge tubes can be used to mix and prepare solutions of various chemicals or reagents. They are convenient for handling small volumes of liquid and can be easily sealed with a cap or closure.
  3. Storage of samples: Microcentrifuge tubes can be used to store small amounts of samples for later analysis or experimentation. They are convenient for this purpose because they are small, lightweight, and can be easily sealed.
  4. Sample concentration: Microcentrifuge tubes can be used to concentrate samples by centrifuging them at high speeds to remove excess liquid. This can be useful for purifying samples or removing contaminants.
  5. Mixing and homogenization: Microcentrifuge tubes can be used to mix and homogenize samples by shaking or vortexing the tubes. This can be useful for breaking up cells or tissue, or for mixing reagents.
