Often patients are prescribed venous blood in order to analyze it. The results of a blood test give the doctor the opportunity to make an accurate diagnosis and, as a result, prescribe treatment. For several years, laboratories have been taking samples not with a syringe, but using vacuum tubes. This method is less painful for the patient and simplifications for the laboratory assistant. The process of blood sampling by a vacuum tube eliminates the moment of blood interacting with air, the external environment, which contributes to more accurate results. Vacuum tubes are equipped with caps of different colors. The color of the cap depends on which chemical is inside the tube. They can be different, since the fence is produced for various analyzes.
Since each patient donates blood for different purposes, the laboratory technician needs to quickly find out which reagent should be inside the tube. To do this, the tubes have special information with a description of the reagent, or lack thereof, and the tubes differ in this feature by the color of the cap so that the laboratory technician can make a quick selection. Thanks to this, it is possible to minimize the number of errors in the collection of material, its processing and research.
We offer a wide selection of vacuum tubes with different color caps.
The structure of the vacuum tube:
double-sided gila;
holder;
vacuum test tube.
The flow of blood into the test tube is ensured by a metered vacuum.
One part of the needle is designed to puncture the vein, the other is covered with a protective rubber cover, to puncture the cork.
As a rule, covers consist of two elements - a rubber stopper and a plastic case, which is indicated by one or another identification color indicating the specificity of the filler.
As for the form, a recess is sure to be present on the lid of the vacuum tube, protecting it from contact with blood, which may remain after the material is taken.
Vacuum tubes for blood sampling by color:
Vacuum test tube with a red cap.
With coagulation activator - designed for effective blood coagulation for the study of serum in biochemistry, immunology, serology.
Vacuum tube with a yellow cap.
With gel and coagulation activator - when centrifuged, it flows from the bottom of the tube, forming a stable barrier between serum and blood cells. For the study of serum in biochemistry, immunology, serology.
Vacuum tube with a purple cap.
With K2 EDTA - designed to study whole blood in hematology. K2EDTA is mainly used for molecular diagnostics, hematological studies of whole blood.
Vacuum tube with a purple cap.
With K3 EDTA - designed to study whole blood in hematology.
Vacuum test tube with a blue cap.
With sodium citrate 3.2% (buffer solution of sodium citrate 0.109 mol / l) - is used as an anticoagulant, a study of coagulation.
Vacuum test tube with a blue cap.
With sodium citrate 3.8% (buffer solution of sodium citrate 0.129 mol / l) - is used as an anticoagulant, a coagulation study.
Vacuum tube with a gray cap.
With sodium fluoride - glycolysis processes are deactivated, purpose: blood glucose test.
Vacuum test tube with a white cap.
No filler - for blood sampling.
Vacuum test tube with a green cap.
With sodium heparin - to suppress blood coagulation, to study plasma in clinical chemistry, immunology.
Vacuum test tube with a green cap.
With lithium heparin - to suppress blood coagulation, plasma research in clinical chemistry, immunology.
The use of vacuum test tubes for blood by color simplifies the process of laboratory diagnostics and allows you to obtain reliable results of various studies in a short time. Each manufacturer allows a difference in the tone of the color of the cover, but it is not significant and all the nuances can be clarified upon purchase.
Also in our assortment are many conventional test tubes, both glass and plastic.
