It develops and offers services, technology and systems that specialize in treatment, purification, cleaning and hygiene of water in a wide variety of applications. [2] Founded as Economics Laboratory in 1923 by Merritt J. Osborn, it was eventually renamed "Ecolab ...
In vivo staining (also called vital staining or intravital staining) is the process of dyeing living tissues. By causing certain cells or structures to take on contrasting colours, their form ( morphology) or position within a cell or tissue can be readily seen and studied. The usual purpose is to reveal cytological details that might otherwise ...
H&E is the combination of two histological stains: hematoxylin and eosin. The hematoxylin stains cell nuclei a purplish blue, and eosin stains the extracellular matrix and cytoplasm pink, with other structures taking on different shades, hues, and combinations of these colors. [ 5][ 6] Hence a pathologist can easily differentiate between the ...
An LB agar plate showing the result of a blue–white screen. The blue–white screen is a screening technique that allows for the rapid and convenient detection of recombinant bacteria in vector -based molecular cloning experiments. This method of screening is usually performed using a suitable bacterial strain, but other organisms such as ...
Clinical chemistry. Clinical chemistry (also known as chemical pathology, clinical biochemistry or medical biochemistry) is a division in medical laboratory sciences focusing on qualitative tests of important compounds, referred to as analytes or markers, in bodily fluids and tissues using analytical techniques and specialized instruments.

Electrochemical stripping analysis is a set of analytical chemistry methods based on voltammetry [ 1] or potentiometry [ 2] that are used for quantitative determination of ions in solution. [ 3] Stripping voltammetry (anodic, cathodic and adsorptive) have been employed for analysis of organic molecules as well as metal ions.
Echocardiography, also known as cardiac ultrasound, is the use of ultrasound to examine the heart. It is a type of medical imaging, using standard ultrasound or Doppler ultrasound. [ 1] The visual image formed using this technique is called an echocardiogram, a cardiac echo, or simply an echo . Echocardiography is routinely used in the ...
A blood smear is made by placing a drop of blood on one end of a slide, and using a spreader slide to disperse the blood over the slide's length. The aim is to get a region, called a monolayer, where the cells are spaced far enough apart to be counted and differentiated. The monolayer is found in the "feathered edge" created by the spreader ...
