Ok, it's 1.5 mg per mL of Blood, you can reach this concentration by disolving 0.6 mg of EDTA in 10 mL of still water, then you add 100 microLitters (0.1mL) of this 6% EDTA into a glass tube. The next thing you've to do is to dry the test tube so that you'll only have 6 mg of EDTA, enough to anticoagulate exactly 4 mL of fresh complete blood. The final concentration of EDTA in the blood should be into the range of 1.25 to 1.75 mg per mL. I found this in Dacie's Haematology. karlosgb@live.com.mx
Lavender (EDTA) top tube. Hyperlipidemic or hyperbilirubinemic samples should not be tested. - excerpted from Bakerman's ABC's
It all depends on what system your using. If by tube you are referring to vaccutainers (blood sample containers) then you have to check. I know that purple top (EDTA) is for the ABC CBC machine as well as a manual blood smear since you need whole blood and EDTA minimizes any distortions.
It is a buffer used in biology. "te" is derived from its components: t from tris, a common pH buffer, and e from the EDTA, a molecule. The purpose of TE buffer is to solubilize DNA or RNA, while protecting it from degradation.
increasing the concentration increases the rate of the reaction
yes you can, however you need the chemical coumpound name, how many grams of that chemical compound was used, and the litres that it was mixed with. for example: 2g of NaF was used to mix in a 1L solution (NaF has a molas mass of about 42g) 2g of NaF x 1 mol/42g (grams cancel and left with mols) 0.048mol/1L = 0.048mol/L conentartion
EDTA
the mass of the EDTA used to prepare 1L oi solution is 18.612g. The formula mass is 372.24 g/mol. Therefore concentration of the 50x solution is: 18.612 g 1 mol ----------- x --------- = 0.050000 mol/L = 50.000 mM 1L 372.24 g
Used in solarcaine.
EDTA is ethylenediaminetetraacetic acid; the chemical formula is C10H16N2O8.EDTA can react with calcium and magnesium ions forming insoluble precipitates.
0.9
yes
EDTA (Na2H2EDTA.2H2O) is 374.24g/mol Be careful not to confuse pure EDTA with the required EDTA used in the lab. C10H12N2O8•4Na is the correct chemical formula for lab use and is the MW above.
EDTA used analytically is usually the disodium salt Na2H4Y 2H2O (372.24 g/mol), which is .... anyremaining EDTA titrant, Ca standard stock solution, and Zn unknown solution ...
K2 EDTA are blood collection tubes that are used throughout the medical field. These tubes are designed to inhibit the coagulation of blood.
EDTA is used in manufacturing to improve emulsification. At home, you yourself can control the rate of addition of oil to protein, so there is no need for you to add EDTA to your homemade mayonnaise. All your mayo needs is oil, egg yolk and a splash of vinegar.
Lavender Top Tube, EDTA
1. Direct Titration In direct titration, you simply add an indicator to the solution of the metal ion and titrate with EDTA. Before starting the titration,it is needed to check that the pH of the solution to obtain a good formation constant value and on the other hand indicator colour change as well. 2.Indiract titration EDTA can be used as titrant for anions. Anions can be precipitated with suitable metal ion. Filter and wash the ppt with proper solution. Then boil in excess EDTA to complex metal ion(ppt). Back titrate to determine how much metal ion you had. 3.Back Titration In a back titration an excess of EDTA is added to the metal ion solution, and the excess EDTA is titrated with a known concentration of a second metal ion. The second metal ion must form a weaker complex with EDTA than the analyte ion so the second metal does not displace the analyte ion from its complex with EDTA. 4.Displacement titration Here the analyte is treated with an excess of a second metal bound to EDTA. The analyte ion displaces the second metal from the EDTA complex, and then the second metal is titrated with EDTA.
