Devices for environmental and temperature control The TFC 100 is a liquid tempera-ture control unit for the tempera-ture setting from - 10…130 °C by an optional liquid circulator bath and under protective atmosphere (inert gas inlet). The triple diffuser TDI 100 is a recommended attach-

ment for working temperatures below room temperature to pre-vent condensation by directing a dry gas flow towards the chamber windows. The TFC 100 is expand-able with a humidity sensor.

The TPC 150 is a temperature control chamber with a peltier system for the software controlled tempera-ture setting from -30…160 °C (heat up and cool down rate ±1 K/s), also under protective atmosphere (inert gas inlet). The triple diffuser TDI 150 is a recommended attachment

for working temperatures below room temperature to prevent con-densation by directing a dry gas towards the chamber windows. The TPC 150 is expandable with a humidity sensor.

The TEC 400 and TEC 700 are tem-perature control chambers with twin electric resistance heater for the software controlled tempera-ture setting up to 400 °C respec-tively 700 °C, also under protec-tive atmosphere (inert gas inlet).

The NHD 400 an NHD 700 are electrical needle heating devices for generating drops at tempera-tures up 400 °C respectively 700 °C (i.e. polymer and hot melts, molten metals, dosing of high viscous liquids etc.). Also extremely tena-cious copolymers with viscosities in the kPas range, e.g. with elastomer constituents, can be dosed easily.

The MTF 1200 and HTFC 1800 are electrical heated high tempera-ture furnaces for the manual or software controlled temperature setting up to 1800 °C under pro-

tective atmosphere. The special ‘LHT’ versions of the OCA-series are designed for use with the high temperature furnaces.

The HTFQ 1200 HV is a high tem-perature (up to 1200 °C) and high vacuum system (down to 1 mPa).

The PMC-50S is a high pres-sure system for up to 80 °C and 5·106 Pa.

Software for environmental and temperature controlThe SCA 20 software, developed for Windows XP®/Vista®, supports all the temperature and environ-mental control systems. This software features simple and intuitive usability and control of all hardware components. Up to four measured temperatures can

be stored, presented and analyzed (in Celsius, Fahrenheit or Kelvin). Individually programmable tem-perature sequences allow the automatic control, analysis, and presentation of temperature sweeps for sessile drop, pendant drop, and lamella analysis without user interaction.

The software module SCA 23 is an unique way to determine the surface tension of high-viscous materials by analyzing the lamella contour. In particular, the analysis of polymer and metal melts or

In close cooperation with cus-tomers, research institutes, and universities we have developed a wide range of special-purpose extensions to the OCA instru-ments, to broaden the range of surface chemistry applications in laboratory and process applica-tions.

return to the equilibrium on its interface. In the ensuing response time the surface and interfacial tensions can be measured and their behavior investigated. Devel-opments of synthetic eye and lung fluids for medical purposes have already profited from this idea, and more innovative applica-tions are expected in the field of protein and surfactant engineer-ing.

Oscillating drops For the measurement of surface elasticities and for relaxational studies at phase boundaries, DataPhysics has developed the oscillating drop generator ODG 20 and the innovative oscillating drop generator ODG 20P with a high resolution pressure sensor. This extension to the optical con-tact angle measuring and drop contour analysis systems of the OCA series – based on a piezoelec-tric transducer – excites oscillating drops with a wide range of fre-quencies and amplitudes. Periodic variations in the drop volume, or alternatively in the drop shape with constant volume, can be per-formed. The excitation frequency ranges up to 50 Hz, depending on the density and viscosity of the fluid. The amplitude of the axis-symmetric oscillations varies from

axis-symmetric drop shape oscil-lations,

• relaxational mode following the instant increase/decrease of the drop volume.

• pressure measuring mode with automatic drop volume tracking and an increased accuracy and resolution of the dilatational modulus,

• analysis of the real and imagi-nary part of the interfacial dila-tational modulus based on the oscillating or relaxing contour of pendant drops.

• analysis of the relaxational modulus.

High-speed camera systemsAll OCA systems can be extended with the high-speed image pro-cessing system UpOCAH with up to 1000 images per second. The OCA 20, 30, 35 and 40 can be upgraded with the high-speed image processing system UpHSC 1000 (up to 1600 images per second), or with the UpHSC 2000 (up to 2200 images per second). Both UpHSC uses

The wetting properties of com-mon solids can be measured with electronic tensiometers which has been evolved to dynamic contact angle meters. The ease of use in providing highly reproducible results with these instruments has been achieved by extensive application of internal and exter-nal computer control. In addition, instruments such as the tensio-meters DCAT 11EC, DCAT 11, or DCAT 21 provide a very high level of automation in the determi-nation of wetting properties exhibited by powders, fibers, and

video-based measuring instru-ments from DataPhysics. In a compact design, the SVT 20N is intended to supersede the tradi-tionally manual operation of these tensiometer systems.With the additional feature of video contour recognition and evaluation technology, an impor-tant contribution can now be made to research in raw materi-als for emulsions, encapsulated drops, and tertiary oil recovery to the advantage of product quality and the preservation of the envi-ronment.

Specifically the SVTS software package for the SVT 20N spinning drop video tensiometer has prof-ited from the wealth of precise and reliable methods to evaluate drop contours, e.g. the Young-Laplace method with statistical error analysis, which is also used for the optical contact angle mea-suring instruments of DataPhysics.
