Petri dishes can be used to visualize the location of contamination on surfaces, such as kitchen counters and utensils, [34] clothing, food preparation equipment, or animal and human skin. [ 35 ] [ 36 ] For this application, the Petri dishes may be filled so that the culture medium protrudes slightly above the edges of the dish to make it ...
A close up of an inoculation needle. An inoculation needle is a laboratory equipment used in the field of microbiology to transfer and inoculate living microorganisms. [1] [full citation needed] It is one of the most commonly implicated biological laboratory tools and can be disposable or re-usable. [1]
used for puncturing into the spine (or cisterns or fontanelles of a new born) for cerebro-spinal fluid aspiration or for injection drugs, specially anesthetics in spinal blocks, epidurals, etc. Ryle's tube or Nasogastric tube: used for nasogastric suction of ingested toxins (or at times introduction of food or drugs). video link
Round-bottom flasks are often used to contain chemical reactions run by chemists, especially for reflux set-ups and laboratory-scale synthesis. [3] Boiling chips are added in distilling flasks for distillations or boiling chemical reactions to allow a nucleation site for gradual boiling. This nucleation avoids a sudden boiling surge where the ...
A Soxhlet extractor is a piece of laboratory apparatus [1] invented in 1879 by Franz von Soxhlet. [2] It was originally designed for the extraction of a lipid from a solid material. Typically, Soxhlet extraction is used when the desired compound has a limited solubility in a solvent, and the impurity is insoluble in that solvent. It allows for ...
Erlenmeyer flasks are also used in microbiology for the preparation of microbial cultures. Erlenmeyer flasks used in cell culture are sterilized and may feature vented closures to enhance gas exchange during incubation and shaking. The use of minimal liquid volumes, typically no more than one fifth of the total flask volume, and baffles molded ...

McIntosh and Fildes' anaerobic jar is an instrument used in the production of an anaerobic environment. This method of anaerobiosis as others is used to culture bacteria which die or fail to grow in presence of oxygen . [1] [2] It was originally introduced by James McIntosh, Paul Fildes and William Bulloch in 1916. [3]
