What is the purpose of thixotropic gel in an evacuated tube?
The gel seperates the cells from the serum or plasma. The gel is "activated" or becomes more viscus as it is being centrifuged and stays between the cells and the serum/plasma
Is a red top tube referred to as a serum separator tube?
Depends who you buy your red top tubes from, but mostly no. A serum seperator tube (SST) is usually yellow or gold top, it has a lump of clear gel in the bottom. When spun this gel ends up between the serum and red blood cellsmaking it easier to seperate the serum. A red top is generally a tube with nothing at all in it. So when spun you end up with serum and clotted red cells but nothing seperating them. Most other colour tubes contain an anti coagulant preventing the blood from clotting so when spun you end up with plasma and red cells. The important thing for most tests is the difference between serum and plasma, so a red top and an SST can generally be used for the same tests although SST is often prefered as its easier to work with.
Why is the serum separator tube used?
The Serum Separator tube is used when they want to test the serum of the blood. For tests like (NA, K, CL, CO2, LD, HDL) any type of chemistry. It is also used for tests like neonatal bilirubin or an AFP non maternal. There is special gel that separates blood cells from serum, as well as particles to cause blood to clot quickly. The blood sample may then be centrifuged, allowing the clear serum to be removed for testing.
What color tube is used in electrolyte panel?
SST or gel separator tube
What is a tube of toothpaste in chemistry?
Toothpaste is a colloidal gel.

What is the purpose of the gel inside of certain tubes?
For venous blood specimens, if it is test tubes used in blood collection that you are referring to, the gel is a serum separator. When the sample is centrifuged, the red cells will spin to the bottom, plasma to the top, gel separating the blood components.
What is that stuff in the bottom of a vial when blood work is drawn?
You are probably seeing the serum separator gel. After the blood in the tube clots, they spin it to separate the clot from the remaining fluid (serum). The gel will move in between the clot and the serum so they stay separated.
What is Serum separator tube SST?
SST Tube stands for "Serum Separator Tube"This is a gel and clot activator tube that is used for clinical biochemistry and immunology. Inside the tube, there is a barrier gel present at the bottom, which is a pure substance, very stable in physical and chemical features. Even under a high temperature, the barrier will not change inside at all. After centrifugation, the barrier can effectively separate the serum from fibrin and cell, while preventing substance exchange between blood cell and serum.
What does the gel in a 'vacutainer' tube consists of?
Some vacationers contain additives coated along the inside of the container without any gel. The gel in a vacationer is an intermediate density between blood cells and serum so that when centrifuged, the gel can keep the blood cells and serum from remixing. The gel consists of semi-solid inert gel composed of a number of compounds.

What is the function of the gel?
Separating gel allows the separation of protein molecules according to their molecular weight by sieving effect of pores in the gel(percentage). The pH of separating or resolving gel is 8.8, whereas stacking gel (upper gel that squeezes protein as a thin layer) made of pH6.8.
What is a form of gel-like barrier between serum and the clot in a coagulated blood sample?
serum separators
What materials do you need to do a gel electrophoresis?
depends on what your separating??
Serum separator tubes used in hematology may not be used when collecting blood for a?
Serum Separator Tube (SST ™') for serum determinations in chemistry and serology. Contains separator gel and should not be used for toxicology or drug testing. Inversions ensure mixing of clot activator with blood. Blood clotting time 30 minutes.
What color tube is a gel-barrier tube?
red
