Syringes: Disposable gloves: prevention of transmission of diseases (as long as not cut or perforated) to or from the user Tourniquet: This is used to cause an artificial venous stasis by applying pressure through this rubber tube. This leads to engorgement of the veins, allowing them to be seen more easily. Used for intravenous injections and ...
A nasogastric tube is used for feeding and administering drugs and other oral agents such as activated charcoal. For drugs and for minimal quantities of liquid, a syringe is used for injection into the tube. For continuous feeding, a gravity based system is employed, with the solution placed higher than the patient's stomach.

Orange Clot activator and serum separating gel [5] Rapid serum-separating tube (RST). Dark green Sodium heparin (anticoagulant) Chromosome testing, HLA typing, ammonia, lactate: Light green Lithium heparin ...
These tubes are usually made of glass, but can also be made of plastic or metal. They vary in size and purpose. Laboratory sample tubes must not be confused with glass tubing, which can be utilized to carry fluid between laboratory equipment. Example laboratory sample tubes are listed below: Ignition tube; Test tube; Boiling tube; NMR tube
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 ...
Hypodermic needles are normally made from a stainless-steel or Niobium tube [17] through a process known as tube drawing where the tube is drawn through progressively smaller dies to make the needle. The end of the needle is bevelled to create a sharp pointed tip, letting the needle easily penetrate the skin. [18]
The sealed syringe is taken to a blood gas analyzer. [8] If a plastic blood gas syringe is used, the sample should be transported and kept at room temperature and analyzed within 30 min. If prolonged time delays are expected (i.e., greater than 30 min) prior to analysis, the sample should be drawn in a glass syringe and immediately placed on ...
with pressure equalizing tube; pear shaped, graduated and ungraduated; Pressure-equalizing dropping funnels have an additional narrow-bore glass tube from the bulb of the funnel, to the ground glass joint around the stem. These replace the liquid volume lost in the bulb with the equivalent gas volume from the flask into which the reagent is ...
