Chemistry stencils that used to be used for drawing equipment in lab notebooks. A laboratory notebook ( colloq. lab notebook or lab book ) is a primary record of research . Researchers use a lab notebook to document their hypotheses , experiments and initial analysis or interpretation of these experiments.
used in photochemical analysis and quantitative estimation of substances such as blood sugar, creatinine, and hemoglobin. Burette: used to measure the amount of acid or alkali used in titration: General laboratory stands, racks, filter paper, reagents, etc. Induction coils: as a source of high voltage electricity Cathode ray oscilloscope ...
Laboratory informatics is the specialized application of information technology aimed at optimizing and extending laboratory operations. [1] It encompasses data acquisition (e.g. through sensors and hardware [2] or voice [3] [4] [5]), instrument interfacing, laboratory networking, data processing, specialized data management systems (such as a chromatography data system), a laboratory ...
The term dot matrix printer is used for impact printers that use a matrix of small pins to transfer ink to the page. [17] The advantage of dot matrix over other impact printers is that they can produce graphical images in addition to text; however the text is generally of poorer quality than impact printers that use letterforms (type).
An electronic lab notebook (also known as electronic laboratory notebook, or ELN) is a computer program designed to replace paper laboratory notebooks. Lab notebooks in general are used by scientists , engineers , and technicians to document research , experiments , and procedures performed in a laboratory.
It also provides instructions on digital design sharing, Arduino microcontrollers, RepRap 3D Printers for scientific use and how to use open-source hardware licenses. The Guardian discusses how ideas in the Open-Source Lab could enable 3D printing to offer developing-world scientists savings on replica lab kits. [2]
Preservation of results. It is important to record and/or preserve the results of a test, especially if the test is positive (i.e., indentations were developed). This can be done in at least two ways. Adhesive lift: in this method, a sheet of fixing film is used to preserve the developed indentations.
Toner is a powder mixture used in laser printers and photocopiers to form the text and images on paper, in general through a toner cartridge. Mostly granulated plastic, early mixtures added only carbon powder and iron oxide ; now there are mixtures that contain polypropylene , fumed silica , and various minerals for triboelectrification .
