Polyvinylpyrrolidone (PVP – K30)Reagent CAS No.:9003-39-8 250g

£54.99

POLYWINYLOPIROLIDON – PVP K30

Chemical reagent CAS No.:9003-39-8

Form: white powder

Contents: min. 99.0%

Chemical formula: (C6H9NO) n

Molecular weight: about 25-30000 g / mol

APPLICATION: It is used as a component of biopolymers, for obtaining colloidal gold and silver.
Polyvinylpyrrolidone (PVP), also commonly called polyvidone or povidone. This type can be used for plant tissue culture applications, allowing inactivation by binding of polyphenols and alkaloids which are produced from explants. It is an alternative to active carbon which does not darken the media, keeping the root zone visible.

Typical concentrations: 0,5 – 2 g / L

Examples for technical usage of PVP:
-as an emulsifier and disintegrant for solution polymerization
-for production of membranes, such as dialysis and water purification filters
-as an aid for increasing the solubility of drugs in liquid and semi-liquid dosage forms (syrups, soft gelatine capsules)
-as an inhibitor of recrystallisation
-as a surfactant, reducing agent, shape controlling agent and dispersant in nanoparticle synthesis and their self-assembly
-as a stabilizing agent in all inorganic solar cells

As a food additive, PVP is a stabilizer and has E number E1201. PVPP (crospovidone) is E1202. It is also used in the wine industry as a fining agent for white wine or some beers.

Chemical Grade Definitions:

Pure p.a – High purity analytical reagents. Suitable for laboratory and general use.

Pure – Good quality chemicals. May be used for most laboratory purposes, educational, domestic, craft applications. Not pure enough to be offered for food.

Technical – Good quality for educational, domestic, handicraft, agricultural applications. Not pure enough to be offered for food.
