OCA 15 LHT with high temperature furnace MTFQ 1200Features of the OCA 15plusWhether your application demands theevaluation of contact angle or drop shape,the video-based optical contact anglemeasuring system, OCA 15plus, may be theinstrument of choice where initial budgetsare limited. It is designed for applicationsthat can be comfortably addressed witha single electronic syringe unit, ES, and donot demand automated measurement ortemperature and atmosphere control fortheir samples. The OCA 15plus is availablein the variants: OCA 15Lplus, OCA 15XL,OCA 15LHT, and OCA 15LHT‐SV. Furthermorethe OCA 15plus is easily upgradableto an OCA 20 (also OCA 15L to an OCA 20Land OCA 15LHT to an OCA 20LHT) or to anOCA 30 (also OCA 15L to an OCA 30L).Components and accessories• sample table with manual adjustment inthree axis via high-precision mechanicsfor an accurate sample positioning• high performance 6x parfocal zoomlens with integrated continuous finefocus, and adjustable observation andcamera tilt angle• video measuring system with USBcamera (52 images/s sample rate), easilyupgradable with the high-speedoption UpUSB52H (max. 146 images/ssample rate) or the high-speed videosystem UpOCAH (max. 1000 images/ssample rate)Thermal chamber TPC 150 with controller TC 150OCA 15plus with single direct dosing system SD-DM andelectronic syringe unit ES• lighting with continuous adjustableintensity without hysteresis• manual multiple dosing system MD/4,• single dosing system SD• single direct dosing system SD-DMfor use with standard and disposablesyringes and needles• one electronic syringe unit ES, softwarecontrolled dosing volume (min. 50 nl)and dosing rate (0.06 µl/s…26.4 µl/s)software controlled adjustable• up to four manual syringe units MS• manual tilting assembly TBA 60M(max. tilting angle 60°)• temperature and environmental controlsystems (‐30…1800 °C and from1 mPa…5·10 6 Pa)• wide range of sample holding and positioningunits like holders for foils orpapers FSH 30 and FSC 80/150, for singlefibers and hairs FHO 40 plus, or thesuction plate SP 100 for holding thinflexible samples flat on the stage withan adjustable suction area• electro wetting platform EWP 100 forthe analysis of sessile and pendant dropsunder a well definable electrical field• top view video system TV-VS for thequalitative documentation of the dropposition (USB camera with 52 images/ssample rate, 6x parfocal zoom lens andadjustable observation angle)Software for efficient workDataPhysics is specialised in the developmentof high-precise and reliablemethods for evaluating drop contoursin combination with statistical erroranalysis. The SCA software assists you inthe intuitive use of the video-based opticalcontact angle measuring instrumentOCA 15plus by specifying measurementprocedures and in collecting, assessing,and evaluating the measured data. TheSCA software is designed as a modularprogram for all OCA instruments. UnderWindows 7® and Windows Vista® itworks in 32- and also in 64-bit mode;NEURTEK S.A.
