A tiger top tube after centrifugation to separate blood cells from serum. Vacutainer tubes may contain additional substances that preserve blood for processing in a medical laboratory. Using the wrong tube may make the blood sample unusable for the intended purpose. These additives are typically thin film coatings applied using an ultrasonic ...
Many jurisdictions desire one item per container, but situations do vary. Clean zipper storage bags are also used: special security bags or “evidence bags” have built-in security and tamper-indicating features. Knives are best suited to packing in corrugated boxes so the blade does not cut the package or people.
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 ...
Blood samples should be allowed time to form a clot at room temperature for 30–60 min. [6] CDC recommends a range of time to allow clot formation that was reasonably consistent, from a minimum of 30 min to 60 min maximum.
Insulated shipping containers are part of a comprehensive cold chain which controls and documents the temperature of a product through its entire distribution cycle. The containers may be used with a refrigerant or coolant such as: [7] block or cube ice, slurry ice; dry ice; Gel or ice packs (often formulated for specific temperature ranges)
Test tubes are convenient containers for heating small amounts of liquids or solids with a Bunsen burner or alcohol burner. The tube is usually held by its neck with a clamp or tongs . By tilting the tube, the bottom can be heated to hundreds of degrees in the flame, while the neck remains relatively cool, possibly allowing vapours to condense ...
Variety of microbiological samples. 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.
Also biobanks, which do specimen storage, cannot take full responsibility for specimen integrity, because before they take custody of samples someone must collect and process them and effects such as RNA degradation are more likely to occur from delayed sample processing than inadequate storage. [5]
