to observe microscopic specimens that cannot be seen by the naked eye. Microtitre plates: mostly used for ELISA: Microtome: cuts prepared specimens for analysis under microscope Nichrome wire loop: used to inoculate test samples into culture media for bacterial or fungal cultures, antibiograms, etc.; sterilized by flaming to red hot before use
A researcher observing a specimen through the built-in microscope in a Class III biosafety cabinet Aerosol control platform inside a Class III Biosafety Cabinet The Class III cabinet, generally only installed in maximum containment laboratories, is specifically designed for work with BSL-4 pathogenic agents, providing maximum protection.
Microbial cultures on solid and liquid media. A microbiological culture, or microbial culture, is a method of multiplying microbial organisms by letting them reproduce in predetermined culture medium under controlled laboratory conditions.
A laboratory specimen is sometimes a biological specimen of a medical patient's tissue, fluids, or other samples used for laboratory analysis to assist in differential diagnosis or staging of a disease process. These specimens are often the most reliable method of diagnosis, depending on the ailment.
Culture tubes are test tubes used in biology and related sciences for handling and culturing all kinds of live organisms, such as molds, bacteria, seedlings, plant cuttings, etc.. Some racks for culture tubes are designed to hold the tubes in a nearly horizontal position, so as to maximize the surface of the culture medium inside.
Biological specimens in an elementary school science lab. A biological specimen (also called a biospecimen) is a biological laboratory specimen held by a biorepository for research. Such a specimen would be taken by sampling so as to be representative of any other specimen taken from the source of the specimen. When biological specimens are ...
Typical information linked to a specimen would be the specimen's origin and when it arrived at the biorepository. (ii) Processing of specimens is standardized to minimize variation due to handling. Processing may prepare the specimen for long-term storage.
Preparation of microbiological samples in a laminar chamber. A laminar flow cabinet or tissue culture hood is a partially enclosed bench work surface designed to prevent contamination of biological samples, semiconductor wafer, or any particle-sensitive materials.
