Malvern Panalytical Zetasizer sample data sheet DTS1235 MRK1753

DTS1235 MRK1753 is a Zetasizer zeta potential transfer standard consisting of carboxylated polystyrene latex dispersed in a pH 9.2 buffer. It is supplied ready-for-use in 10 mL syringes and is used to verify and validate zeta potential instrument performance by providing a stable, known zeta potential value for measurement checks and routine verification.

Key Features:

• Transfer standard identification: DTS1235
• Manufacturer internal/reference code: MRK1753
• Material: carboxylated polystyrene latex in pH 9.2 buffer
• Packaged: ready-for-use 10 mL syringes
• Specified zeta potential: -42 ± 4.2 mV

Advantages:

• Provides a stable, ready-to-use reference for verification and validation of zeta potential measurements
• Simplifies routine instrument checks by eliminating sample preparation (supplied in 10 mL syringes)
• Delivers a defined, manufacturer-specified zeta potential value to support consistent performance assessment
