Since centrifuges spin very rapidly it is important that when placing something in one side to balance it with an equal mass on the opposite side. This weight usually consists of a test tube or microcentrifuge tube that is filled with water or whatever solvent is being used. A roughly equal mass can usually be obtained by pouring a similar volume of the solvent being used into the same type of container. For ultracentrifugation and larger samples it is important to match up masses accurately using a scale.
If the centrifuge is not balanced when started it could cause it to wobble and potentially cause damage to the machine or it's surroundings.
What else can I help you with?
What spins test tubes holding mixtures of disrupted cells at various speeds?
A centrifuge spins test tubes holding mixtures of disrupted cells at high speeds to separate the components based on their density. This process, called centrifugation, allows the different cell components to settle at different levels within the test tube, aiding in their isolation and analysis.
What does centrifuge tube use for?
Centrifuge tubes are commonly used in laboratories to separate components of a liquid mixture based on their densities. When placed in a centrifuge, the tube spins at high speeds, leading to the formation of layers of different components in the liquid. This process is used for various applications such as isolating DNA, separating blood components, and purifying samples for analysis.
Hematocrit sealed end of the tube toward the outside of the centrifuge rack?
If the hematocrit is sealed at the end of the tube toward the outside of the centrifuge rack, this ensures that the hematocrit is properly centrifuged with the red blood cells compacted at the bottom. This positioning helps in accurate measurement of the packed cell volume, which is an essential parameter in assessing the patient's blood composition.
What is 13x100 test tube?
A test tube 13 mm (about half an inch) in diameter and 100 mm (a bit under 4 inches) long.
What happens to the level of water in a test-tube as hydrogen is produced?
Ya... In a test tube add some aluminum foils and some amount of NaOH... Introduce the flame near mouth of the test tube... Then see the magic...
What machine spins the test tube?
Centrifuge
An instrument used to separate and compact a precipitate in a test tube is called?
A centrifuge is used to separate and compact a precipitate in a test tube by applying rapid spinning forces.
What test tube is used for separating sediment from urine?
The tube is not so important . It's the centrifuge that does the work.
The difference of centrifuge and test tube?
A tapered and specially-engineered test tube specifically for centrifuge work, designed to resist the high G-forces induced by the centrifugal forces. They are mainly used in medical work to centrifuge human blood for test purposes. despite all the potential hazards I have never heard of a centrifuge accident or explosion if used properly with all safety devices employed. there was a tale in a Gotham paper of a centrifuge (Open and uncovered) blowing up with an induced chemical reactionk, certtainly not SOP. a teacher or student had some mild splash burns.
DO YOU CENTRIFUGE RED TUBE?
To centrifuge a red tube you will have to run the blood through and then put it back into the body. The red tube is used to collect plasma.
What is the centrifuge tube used for?
A centrifuge is used for separating components in a liquid that have different weights.
How do you describe a centrifuge tube?
A centrifuge tube is a tool that is used in laboratory research. They are tapered tubes that come in a variety of sizes and are made of plastic or glass.
How long do you centrifuge blood?
Depends on what kind of tube/test you are performing? 10-15 min usually. 20 min on rare tests.
Why do you need a place a second tube into centrifuge?
Balance.
What is the weight of a micro centrifuge tube that has 500ul of 2M CaCl2 in it?
Well, can't tell you off the top of my head, but if you cruise into a lab and throw 500 ul of 2M CaCla2 into a centrifuge tube, put it on a scale and you will have your answer. I mean really? The point of lab is to do it!
How did Earth's layers develop?
Gravity and Centrifugal force causes the layers to settle, in a similar way to why a centrifuge causes blood in a test tube to split into different groups of material like platelets ect.
What is the wooden stick used for after the centrifuge of a red top tube?
To beat you if you haven't balanced the centrifuge before spinning, lol.
