Contact Angle Meters of the OCA series
Entry-level Contact Angle Meter
The optical contact angle meters of the OCA series are high-precision measuring systems for the characterisation of interfaces and surfaces. They combine high-resolution optics, pinpoint liquid dosing and precise sample positioning to create powerful measuring systems. The entry-level model OCA 15EC enables basic contact angle measurements and drop shape analyses. Thanks to the modular construction, even this entry-level model can be fitted with many accessories.
Standard Contact Angle Meter
The OCA 25 standard model is the all-purpose system for contact angle measurements and drop shape analysis. The high-performance camera makes it possible to measure contact angles even on adsorbent surfaces such as tissues or powders. Compared to the entry-level OCA 15EC, additional measurements at higher temperatures of up to 700 °C are possible. Further advantages are the more precise positioning of the sample table as well as the compatibility with many more dosing systems, which allow electronic dosing and droplet volumes down to a minimum of ten nanolitres.
Premium Contact Angle Meter
The premium model OCA 50 is a fully automatic contact angle meter. It is suited perfectly to investigate the wettability of solid surfaces and determine their surface energy. Since the sample stage is electronically adjustable, complete measurement sequences can be run automatically, ensuring reliable results. Additionally, the OCA 50L can measure even on large 12″ wafers and other, larger, samples.
Expert Contact Angle Meter
The expert model OCA 200 is the contact angle measuring instrument for microscopic and macroscopic structures. Thanks to the 10x zoom lens and the autofocus system, it is suitable for any sample size from the macroscopic silicon wafer to the microscopic metal struts of a coronary stent. Together with the FDDS FlexDrop dosing system, the OCA 200 allows the analysis of droplets with a minimum volume of 25 picolitres.
Special Contact Angle Meter
The special model OCA 25-HTV is suitable for measuring contact angles at high temperatures of up to 1800 °C and in a vacuum of up to 0.00001 mbar or in an inert gas atmosphere. With an optional dosing system, the OCA 25-HTV can also be used at room temperature for all standard analyses such as the determination of surface energy and the measurement of interfacial tensions.
Special Contact Angle Meter
With its high-pressure measuring chamber, the special model OCA 25-PMC offers the possibility of carrying out measurements of interfacial tensions and contact angles under high-pressure of up to 750 bar and at temperatures between -30 °C and 200 °C.
