What is Carbowax used for?
They are used commercially as solvents for dyes, natural resins, and proteins. They are also used as plasticizers for Casein, Gelatin, glue, Zein, Cork, and inks. Carbowax® formulations have also been used to slowly replaced water in water-logged wood providing structural support while decreasing wetness.
Is PEG 4000 water soluble?
A simultaneous TG-DSC method has been used for the determination of ethanol-water solutions containing PEG 4000. The solubility limit increases from approximately 80 weight percent at 40°C to 87 percent at 50°C in a 70/30 weight percent ethanol-water solution.
What is the difference between PEG 4000 and PEG 6000?
PEG 6000 is more effective than PEG 4000 for a protoplast transformation, but it is also possible to increase the concentration of PEG 4000 but it is also possible to increase the concentration of PEG 4000 in order to compensate for its low molecular weight.
What is carbowax column?
Carbowax 20M High Polarity GC Columns from Agilent Agilent J&W Carbowax 20M are polyethylene glycol (PEG) columns equivalent to USP phase G16. Their temperature range of 60 to 220 ºC is ideal for alcohols, free acid, ether, glycol, and solvents.
Is carbowax an embedding medium?
a previous report,3 certain modifica- tions of earlier methods1,2- 5′ 6 of embedding tissues in Carbowax were described. Carbo- wax, a solid polyethylene glycol, is a valuable embedding medium because, with its use, alcohol-soluble substances such as lipids are not removed during the preparation of tissue sections.
What does PEG 4000 mean?
Polyethylene glycol 4000 (PEG 4000, Forlax) is a non-toxic, hydrosoluble, high-molecular polymer, which is not absorbed in the gastrointestinal tract following oral administration. PEG 4000 acts as an osmotic agent that increases fecal water content.
Is Carbowax column Polar?
