Other examples of inorganic polyprotic acids include anions of sulfuric acid, phosphoric acid and hydrogen sulfide that have lost one or more protons. In organic chemistry and biochemistry, important examples include amino acids and derivatives of citric acid. Although an amphiprotic species must be amphoteric, the converse is not true.
Blood culture bottle: Sodium polyanethol sulfonate (anticoagulant) and growth media for microorganisms: Usually drawn first for minimal risk of contamination. [1] Two bottles are typically collected in one blood draw; one for aerobic organisms and one for anaerobic organisms. [2] Blue ("light blue") Sodium citrate (weak calcium chelator ...
In the 20th century, the use of blood and serum collected and dried on a filter paper for serologic testing for syphilis was already reported. Both field and home sample collections were described. [3] The first report of blood absorbed onto filter paper for enzyme measurements was published in 1953. [3] [5]
A vacutainer blood collection tube is a sterile glass or plastic test tube with a colored rubber stopper creating a vacuum seal inside of the tube, facilitating the drawing of a predetermined volume of liquid. Vacutainer tubes may contain additives designed to stabilize and preserve the specimen prior to analytical testing.

A phlebotomy draw station is a place where blood is drawn from patients for laboratory testing, transfusions, donations, or research purposes. The blood is typically drawn via venipuncture or a finger stick by a healthcare professional such as a phlebotomist, nurse, or medical assistant. [21]
The pictures were intended as scientific documentation to support theories of ethnology. Carl Damman published a collection of photographs of different ethnic groups in Anthropologisch-ethnographisches Album in Photographien . and in the same year William Marshall published A phrenologist amongst the Todas, or the Study of a Primitive Tribe in ...
In most cases, blood plasma is returned to the donor as well. However, in locations that have plasma processing facilities, a part of the donor's plasma can also be collected in a separate blood bag (see plasmapheresis). For example, in Australia around 5.9×10 11 platelets and 580 mL of plasma might be collected from an 88 kg donor.
