A preferred material would possess a surface or coating suitable for marking by hand or computer.Īdditionally, the material may be amenable to computer-directed printing with consumer-oriented desktop printers. Such materials offer many of the desired attributes and may be readily die cut. Since the device does not rely on adhesives for application, failure of adhesives resulting in delamination in extreme conditions, like steam, boiling water and liquid nitrogen, is avoided.Ĭandidate materials include, but are not limited to, polyester, PVC (vinyl), polypropylene, and other materials with similar qualities. Preferably, the device is composed of a suitable stock that is moisture-proof, tear-proof or tear-resistant, and is able to maintain indicia in readable form during typical laboratory practice. may be delaminated or distorted when tubes are exposed to certain extreme laboratory conditions, such as immersion in boiling water baths (at 100 C) and liquid nitrogen (at -196 C) masks the tube contents from view, and may also interfere with inserting the tubes into holding racks and centrifuge rotors must be carefully oriented on the tube surface for proper application, and may be subject to abrasion during subsequent tube handling the marking may be inadvertently scuffed or defaced by repeated handling of the tube during laboratory procedures the shiny, non-porous surface of a polypropylene microtube can be marked only with writing implements adapted for such a surface writing by hand on the limited and sharply curving tubular surface or cap of a microtube can be unwieldy and tedious Problems with existing labeling methods. Labeling microtubes has largely been limited to applying identifying information with a writing instrument to the surface of the tube itself, or by fastening an identifier-bearing label thereto. Microtubes (a/k/a microcentrifuge tubes) are a commonly used consumable in research, diagnostic, industrial, and forensic laboratories. The device comprises a markable panel component and an aperture for frictionally engaging the tube barrel. This is helpful for life science applications or applications where molecular biology, cell biology, DNA isolation and purification, cell lysis, pellet formation/re-suspension, preparation for PCR, mixing of viscous liquids or any other method that requires tube vortexing and centrifugation of many samples.A novel labeling apparatus adapted for microcentrifuge tubes that is durable, easy to use, and does not interfere with laboratory practice. These units are versatile as they can hold un, semi and fully skirted PCR plates to allow for PCR plate centrifugation or plate mixing. There are combined vortex mixer/centrifuges which are centrifuges with vortex mixing to help save time as you can simultaneously prepare multiple samples at once. This is the better option for if you are wanting to separate samples of different sizes. The tubes are placed inside the centrifuge in a fixed position to separate the liquids. This is the better option when you are looking to mix difficult liquids together or to help dissolve something in a solution.Ī centrifuge is mainly used to separate components of different sizes, these are mainly used in biological areas for centrifuging cells. The tubes are placed on top of the vortex mixer to mix the liquid. Vortex mixers can be used in all laboratories but are mainly used within microbiology, bioscience, biochemical and analytical lab settings to help mix samples together before analysis, or to suspend cells. Camlab choice centrifuge Do I need a vortex mixer or centrifuge?
