Indicateurs
Les indicateurs sont des substances utilisées dans les titrations et autres analyses chimiques pour signaler un changement de pH ou de composition chimique. Ils sont essentiels pour des mesures précises dans les contextes de recherche et industriels. Chez CymitQuimica, nous offrons une sélection complète d'indicateurs conçus pour garantir précision et reproductibilité dans les applications de laboratoire, notamment pour les réactions acido-basiques et rédox.

Reagecon's Bromophenol Blue Indicator 0.04% Solution is a high quality Indicator Solution produced from the highest quality raw materials and manufactured and tested under rigorous conditions. For manual titrations; indicator titrant or analyte change colour and this colour change is by far the most important method of end point detection, in such titrations. A high quality indicator solution such as Reagecon's Bromophenol Blue Indicator 0.04% Solution facilitates end point detection, in a clear and unambiguous manner and is an imperative for accurate manual titrimetry.Couleur et forme :LiquidSpiro[isobenzofuran-1(3H),9'-[9H]xanthen]-3-one,2',7'-dichloro-3',6'-dihydroxy-

CAS :5-Carboxyfluorescein (5-FAM) is a self-quenching dye and one of the most common labelling agents for biomolecules, cell staining and localisation studies. The fluorescence is pH dependent, therefore it has been used to measure the internal pH of cells. As it is only membrane permeable to dead cells, it can be used as a staining agent to distinguish viable and non-viable cells. It is also used in PCR to label the 5â end of oligonucleotides in the presence of a quencher at the 3â end (dual labelled probe). During the amplification process, the dye is cleaved and the fluorescence increases proportionally with the amount of the specific sequence amplified during the PCR process. The development of the fluorescence signal is therefore specifically related to the amplification of the target sequence. The carboxylic acid can be activated to react with a primary amine.Formule :C21H12O7Degré de pureté :Min. 98 Area-%Couleur et forme :Yellow PowderMasse moléculaire :376.32 g/mol4-Nitrophenol
