What does it mean to counterbalance a test tube in a centrifuge?

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.

∙ 13y agoIn general, it's always a good idea to counterbalance a centrifuge. If you've ever used one that wasn't balanced, you'll know why: they wobble like the dickens. (Think of an out of balance washer in the spin cycle. Now pretend it's going several hundred times faster.)

What does centrifuge tube use for?
it is used fore container of the solution to be centifuge
Hematocrit sealed end of the tube toward the outside of the centrifuge rack?
Centrifugal force dictates blood will attempt to leave the tube away from the axis of rotation. seal tube to avoid problems
Uses of test tube rock?
a test tube rock is used to measure liquids
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 does a test tube measure?
that depends on the kind of test tube that you have. if a test tube is calibrated then it measures the volume of a liquid that is placed inside it. if the test tube is non calibrated then its meant for storage and mixing so it does not measure anything..
What machine spins the test tube?
Centrifuge
What test tube is used for separating sediment from urine?
The tube is not so important . It's the centrifuge that does the work.
An instrument used to separate and compact a precipitate in a test tube is called?
Centrifuge
What vacutainer would you use for a blood chemistry test?
A centrifuge tube would be useful, but a regular test tube will suffice.
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.
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 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.
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.
