Definition of LigandA ligand is an ion or molecule that binds to a central metal atom to form a complex (alternatively known as a coordination entity).
Ligands are atoms or molecules with electron pairs available; they may be neutral or negatively charged. The ligand provides both of the electrons for the bond that forms between itself and the central metal atom or ion.
Examples of monodentate ligands which begin with charges are halide ions, such as: F-, Cl-, Br-, I-, and cyano, CN-. The overall charge on a complex is the arithmetic sum of the oxidation state of the metal in the center plus the charge(s) brought to the complex by each ligand.
For example, if a complex forms between Fe2+ and six CN- ligands, the complex will have a -4 charge, and the formula is written [Fe(CN)6] 4-. Both of the nitrogens in this molecule can act as electron donors, binding with a central metal atom or ion. Other examples of bidentate ligands are the acetylacetonate ion, known as (acac), and the oxalate ion (ox). The thiocyanate ion, SCN- can bind to the central metal at either the sulfur or the nitrogen. EDTA tube is widely used in clinical haematology, cross matching, blood grouping as well as various kinds of blood cell test instruments.

PT tube is used for blood coagulation test and applicable to fibrinolytic system (PT, TT, APTT and fibrinogen, etc.). Complexing agents like EDTA (Ethylendiaminetetraaccetate) or NTA (Nitrilotriacetic acid) have replaced phosphates as additives in washing and cleaning solutions. In proteomics labs EDTA is also used to regenerate Ni- and Co-precharged chromatography columns (FPLC columns) which are used to purify recombinant proteins. Ligands are usually thought of as electron donors attracted to the metal (the electron acceptor) at the center of the complex. 1,4,7-triazaheptane (also known as diethylenetriamine) has three lone pairs of electrons shown in green. It offers a comprehensive protection for blood platelet, so that it an effectively stop the gathering of blood cell, especially for protecting the blood platelet, so that it can effectively stop the gathering of blood platelet and makes the form and volume of blood cell uninfluenced within a long time. Embedding cassettes mainly applied for histology or tissue processing, flow-through strip holes, resistant to chemical action of histological solvents.
Embedding Cassettes have hinged lid or removable lid and it also can be separated from the box. These boxes create small, space-efficient storage system within a large mechanical freezer. Separatory funnel used in the chemical industry, petrochemical industry, electronic chemistry, biochemical pharmaceuticals, laboratory and education.

QUANTOFIX® EDTA is therefore ideal to check the concentration of washing and cleaning solutions. Prior to the successive analysis, QUANTOFIX® EDTA is used to control, if EDTA has completely rinsed out.
If you require further details regarding the transaction data, please contact the supplier directly. Excellent outfits with super-minute technique can spray additive uniformly on the inner surface of the tube, thus blood specimen can completely mix with the additive. This may dramatically reduce the rinse time and therefore increase the throughput and the capacity.
EDTA anticoagulant plasma is used for biological assay of pathogenic microorganism, parasite and bacterial molecule, etc.
As the sodium citrate has little toxicity, it is also used for blood volume to ensure accurate testing result.
