Zeta analyzer

Manufactured by Malvern Panalytical
Sourced in United Kingdom

The Zeta analyzer is a laboratory instrument used to measure the zeta potential of particles suspended in a liquid. It determines the surface charge and stability of colloidal dispersions. The Zeta analyzer provides data on the electrophoretic mobility and the zeta potential of the sample.

Globule size, polydispersity index, and zeta potential of L-SEDDS-Blk. L-SEDDS-FSM and S-SEDDS-FSM were performed on a zeta analyzer (Malvern, Malvern, UK). For this purpose, 100 µL of FBlank and FFSM were diluted in 1 mL of deionized water using a vortex mixer to form nanoemulsions. At the same time, 200 µg of S-SEDDS-FSM was vortexed with 1 mL of deionized water and centrifuged at 3000 rcf for 5 min. The supernatant was collected for measurement. All measurements were taken at 25 in triplicate [38 (link)].

The particle size and zeta potential of caffeoylquinic acid-loaded BP nanoparticles were measured using a Malvern Zeta Analyzer (Malvern, Worcestershire, UK) (Zhu et al., 2023 (link)). The nanoparticle samples were dissolved in deionized water to 1.0 mg/mL at 25 °C and then examined at a fixed scattering angle of 90° using a refractive index value of 1.330.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
