The tube and cap are also sealed with a silicone seal, making them suitable for storage in the gaseous phase of liquid nitrogen (-196 degC).
This product is available non-sterile or sterile, depending on your preference and application. Sterile microcentrifuge tubes can be stored without refrigeration and have a shelf life of 10 years. Non-sterile microcentrifuge tubes are sterilized with ethylene oxide, while sterile tubes are sterilized using steam under aseptic conditions.
1.25 mL Microcentrifuge Tubes
The larger capacity of these microcentrifuge tubes makes them a popular choice for a variety of laboratory applications. They are perfect for pooling media from 15 mL or 50 mL culture flasks, as well as bacteria cultures and many other applications that require more than 0.5 mL of working volume.
Each tube is made from premium polypropylene plastic, which provides a crystal clear tube with superior centrifugal strength and durability. These tubes are also resistant to a wide range of chemicals, including alcohols, bases and acids, phenol and chloroform.
With a snap-lock closure that ensures a secure seal and eliminates leakage, these tubes are easy to use. Audible open/close pops help prevent accidental opening and the locking system is compatible with most standard rotors. These glass-free tubes are rated for up to 30,000 relative centrifugal forces, and are certified free of detectable RNase, DNase, DNA and pyrogens.
These glass-free tubes are perfect for handling sensitive samples, such as RNA and protein solutions. The frosted labeling panels allow for easy writing and identification. They are also autoclavable, which allows them to be used in a variety of different laboratory conditions and applications.
Plastic centrifuge tubes are a more convenient and economical alternative to glass ones. They are less expensive and easier to clean, and they can be sterilized in most laboratory autoclaves. They are also more durable than glass centrifuge tips, which can break more easily and cause contamination.
These molded ribbed polypropylene tubes are made for general lab use, with graduations molded in on both the tube and cap, as well as 2D barcode labels. They are also compatible with a variety of rotary and fixed-angle rotors and can be autoclaved at 121 degC (2 bar, DIN EN 285). The tube and cap are manufactured from medical-grade polypropylene, and feature subdivisions of 0.1, 0.5, 1.5, 2.0 and 5.0 mL, as well as a convenient locking mechanism to prevent accidental opening. The lids are also designed to achieve an exceptionally strong seal and are secured with a catch that helps prevent accidental opening.
0.5 mL Microcentrifuge Tubes
Designed for the centrifugation and storage of small volume samples, reagents, and DNA extracts. Made from robust virgin polypropylene, these clear microcentrifuge tubes are tough and durable. They have flat caps and frosted body surfaces for easy labeling. They tolerate centrifugal forces of up to 25 g-forces and are autoclavable. They are free of RNase, DNase, and pyrogens and are certified sterile.
These high quality 0.5 mL microcentrifuge tubes are available in packs of 50 or 100 sterile tubes and can be resealed with a sealing cap after use. The wide lid rim facilitates manual handling. They are a great choice for the centrifugation of cell culture, molecular biology, biochemistry, and microbiology experiments. They are made from pure granular polypropylene and manufactured with state of the art product equipment housed in a positive pressure HEPA filtered environment. The manufacturing process eliminates processing additives like slip agents and plasticizers avoiding contaminating leachables that interfere with assay quantification.
Microcentrifuge tube dimensions and maximum centrifugal force ratings are important considerations for the proper operation of a laboratory centrifuge. The diameter of the tube determines whether it can be used in a certain size centrifuge, and the maximum centrifugal force rating ensures that the tubes will not break under the stresses of a spinning experiment. The rated maximum relative centrifugal force (RCF) of the tube also dictates the temperatures and lengths of time that can be safely used with the instrument.
When selecting a lab centrifuge, pay special attention to the design of its spin chamber to make sure that the tubes will fit well. Laboratory centrifuges are driven by a motor that accelerates the rotation of a sample to separate materials of different densities. This technique, known as sedimentation, is based on the principle that the heavier substance sinks to the bottom of a container while lighter material rises to the top.
When the centrifuge is turned off, the rotational speed slowly decreases to allow the heavier sample to remain in the middle of the tube. The resulting sediment is then collected by the tube’s sealing rim in a collection tube.
0.1 mL Microcentrifuge Tubes
These microcentrifuge tubes feature a clear polypropylene construction and are autoclavable. They are ideal for molecular biology,clinical chemistry and bio-chemistry research. The high transparency makes them easy to read, and the tube and cover design ensures a quick seal to avoid evaporation during centrifugation. They are certified free of RNA, DNA, Non-pyrogenic and Non-cytotoxic to ensure the highest test result.
Using the right tubes for your laboratory procedures is critical to success. This includes choosing the correct size tube for your centrifuge, ensuring that the tube has a sufficient relative centrifugal force (RCF) rating for your experiment and knowing how to store and handle the samples.
RCF values can be influenced by several factors, including the temperature and duration of your experiment. The higher the RCF, the greater the stress on the sample, which could result in deformation, cracking or breakage if the tube is too small or is made of materials that are not suitable for high-speed centrifugation.
When choosing a microcentrifuge, it is important to know the maximum RCF it can support. If the centrifuge is too powerful, it can damage or break your samples and also strain the rotor. In addition, if the load in the centrifuge is uneven, it could cause an imbalance of forces that strains the rotor and causes it to spin out of control.
If you are looking for a new centrifuge to work with, it is important to consider its RCF ratings and other specifications carefully. In addition to the RCF, it is important to make sure that the centrifuge has a lid and other safety features to prevent injury from accidental contact with the rotor during the spin cycle.
