Preparation accessories refer to a wide range of tools and instruments used in preparing, processing and examining biological samples or specimens in laboratories, research institutes, medical facilities and other scientific disciplines. These tools help perform various techniques and procedures for the analysis and study of biological material. Here are some common preparation accessories:
- Microscope slides and coverslips: Thin glass slides used to mount a sample for microscopic examination. The sample can be observed under a microscope after it has been prepared and covered with a coverslip.
- Slides and Holders: These glass slides are used for preparing and examining thin sections of tissues or cells. They can be used in making histological preparations or cytological smears.
- Dye: Chemicals used to visualize certain structures or components in a sample. Dyes are commonly used in histology, cytology, and microbiology to identify and visualize specific tissues, cells, or organisms.
- Fixation fluids: Chemical solutions used to stabilize and preserve specimens. Fixation is performed to preserve the structure and composition of the sample and prevent degradation. Commonly used fixatives include formaldehyde, alcohol and broth.
- Cutting tools: Instruments such as scalpels, microtomes and tissue homogenizers are used to accurately cut, chop or grind tissue samples for further analysis.
- Centrifuges: Devices used to separate samples based on density differences. Centrifuges apply a force to the samples, causing components such as cells or particles to sink to the bottom of the tube so they can be collected for further analysis.
- Incubators: Devices used to control temperature, humidity and control other environmental conditions to permit the growth and culture of organisms or cells.
- Pipettes: Instruments used to transfer precise amounts of liquids. There are several types of pipettes, such as mechanical pipettes, electronic pipettes, and single-use pipettes.
- Freezing microtomes: Special microtomes used to freeze tissue samples and then cut very thin sections for examination under a microscope.
These are just a few of the various preparation accessories used in various research and medical laboratories. The choice of preparation accessories depends
