Laboratory Applications
PEG 20000 for Biochemical Research
PEG 20000 can be evaluated in suitable biochemical and life science research applications requiring high molecular weight Polyethylene Glycol.
Its polymer properties make it useful in compatible laboratory formulations and experimental systems.
RH1872 provides High Purity Grade >99% PEG 20000 for laboratory research.
PEG 20000 for Laboratory Reagent Formulation
RH1872 can be incorporated into compatible laboratory reagent formulations.
Important formulation factors include:
PEG 20000 concentration
Molecular weight requirements
Buffer composition
pH
Temperature
Other formulation components
Intended application
The appropriate formulation should be optimized according to experimental requirements.
PEG 20000 as a Water-Soluble Polymer
Polyethylene Glycol is a water-soluble polymer available in a wide range of molecular weight grades.
PEG 20000 represents the highest nominal molecular weight PEG grade shown in your current product series.
Different PEG molecular weights can provide different solution, viscosity and formulation characteristics.
PEG 20000 for Research Formulations
RH1872 PEG 20000 can be evaluated as a polymer component in suitable laboratory research formulations.
Potential applications include:
Biochemical reagent development
Polymer formulation research
Laboratory solution preparation
Sample preparation
Biotechnology research
Life science research
Compatibility with the complete formulation should be evaluated experimentally.
PEG 20000 in Life Science Research
Polyethylene Glycol materials are widely used in biochemical and life science research.
RH1872 provides PEG 20000 for compatible research workflows requiring a higher molecular weight Polyethylene Glycol grade.
The appropriate concentration should be determined according to the intended experimental application.
PEG 20000 Molecular Weight Grade
The designation PEG 20000 identifies the Polyethylene Glycol molecular weight grade.
Different PEG grades can exhibit different physical and formulation characteristics because of differences in molecular weight.
Researchers should therefore select PEG 20000 when this molecular weight range is appropriate for the intended experimental system.
PEG 20000 vs PEG 10000
PEG 20000 and PEG 10000 are different molecular weight grades of Polyethylene Glycol.
Product Code | Product | CAS No. | Grade | Package |
|---|---|---|---|---|
RH1872 | PEG 20000 | 25322-68-3 | High Purity Grade >99% | 250 g |
RH0572 | PEG 10000 | 25322-68-3 | High Purity Grade >99% | 250 g |
PEG 20000 has a higher nominal molecular weight than PEG 10000.
PEG 20000 vs PEG 8000
PEG 20000 and PEG 8000 belong to the same Polyethylene Glycol family but represent substantially different molecular weight grades.
Selection should consider the required polymer characteristics, formulation properties and experimental conditions.
The two grades should not automatically be substituted for one another.
Available Polyethylene Glycol Grades
The current product series includes:
PEG 1000
PEG 2000
PEG 3350
PEG 4000
PEG 6000
