Packing Sizes:
Polyethylene glycols (PEGs) are condensation polymers of ethylene oxide. Low molecular weight compounds up to 700 are colorless, odorless viscous liquids while polymerized compounds with higher molecular weight than 1,000 are wax like solids
The reason for for using PEGs with large molecular weight is that smaller PEGs can diffuse through the cell wall and are even taken up by plant cells and distributed through the plant, which may influence the results. larger than 6,000 (PEG 6000) are inert, non-ionic and cell impermeable. to simulate osmotic stress.
Product Application:
Polyethylene glycol, referred to as PEG, is used as an inactive ingredient in the pharmaceutical industry as a solvent, plasticizer, surfactant, ointments and suppository base, and tablet and capsule lubricant. ... PEG is also available as a bowel prep for colonoscopy procedures and as a laxative
Product Dose:
The addition of PEG to a protein solution increases the chemical potential of the protein. Precipitation of the protein occurs when its chemical potential exceeds the level of a saturated solution.

Remarks:
Polyethylene glycols (PEGs) are condensation polymers of ethylene oxide and water with the general formula H(OCH2CH2)nOH. They are the most commercially important type of polyether. The low molecular weight compounds up to 700 are colorless, odorless viscous liquids with a freezing point from -10˚C (diethylene gycol), while polymerized compounds with higher molecular weight than 1,000 are wax like solids with melting point up to 67˚C. While PEGs with different molecular weights find use in different applications and have different physical properties (e.g. viscosity) due to chain length effects, their chemical properties are nearly identical.
The numbers that are often included in the names of PEGs indicate their average molecular weights, e.g. a PEG with n=9 would have an average molecular weight of approximately 400 and would be labeled PEG 400. Most PEGs include molecules with a distribution of molecular weights, i.e. they are polydisperse.
