Oca 25lht

Manufactured by Dataphysics

Sourced in Germany

The OCA 25LHT is a contact angle measuring instrument designed for the analysis of surface wettability. It uses a high-resolution camera and proprietary software to capture and analyze the contact angle formed between a liquid and a solid surface. The instrument provides accurate and repeatable measurements of static, dynamic, and advancing/receding contact angles.

The surface morphology was observed by dual-beam scanning electron microscopy (DBSEM; Helios Nanolab G3 UC, FEI, USA) equipped with energy dispersive X-ray spectroscopy (EDS).
The surface roughness was measured using a confocal microscope (CM; LSM700, Olympus, Japan). The phase composition was detected by an X-ray diffractometer (XRD; Advance D8, Bruker, Germany). The surface chemistry was analyzed using X-ray photoelectron spectroscopy (XPS; ESCALAB250Xi, Thermo Fisher Scientific, USA). The surface wettability was measured by a contact angle meter (CAM; OCA 25LHT, Dataphysics instrument GmbH, Germany).

Comprehensive Characterization of Graphene Oxide

AFM images were recorded on MultiMode 8 AFM (Bruker, Bremen, Germany) in the tapping mode using a silicon cantilever for the geometry of individual GO nanosheets deposited on mica. SEM images were obtained by using a field emission SEM (Hitachi S-4800, Tokyo, Japan) with an acceleration voltage of 10 kV. Contact angle measurement was carried out on an OCA25LHT (Dataphysics, Filderstadt, Germany) instrument at room temperature. XRD patterns were collected on a Bruker D8 Focus diffractometer using an incident wavelength of 1.5418 Å (Cu Kα radiation). The zeta potential of GO colloids (0.1 mg mL⁻¹) was measured with a Malvern Zetasizer NanoZS90.

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.
