The DMe-211 Plus is an economical yet fully-featured contact angle meter with a computer image analysis system. The unit combines manual droplet volume regulation, stage up/down motion for gentle deposition of droplets with “FAMAS-basic” software controlled analysis of static and dynamic contact angle (30fps) as well as surface and interfacial tension using the pendant drop method. Analysis software to determine the surface free energy of solids is a standard feature. - Automatic recognition of droplet deposition - Live image display and droplet volume monitoring - Movie converter - Manual dispenser with a set of 5 glass syringes and 5 SUS needles for precise adjustment of droplet volume and quick refilling and replacement of liquid samples - Fine adjustable stage in z-axis for gentle deposition of droplets without distortion - Adjustable level of the body and stage - Droplet calibration standard for standard view, bearing one full circle for calibration and three droplet silhouettes of 5°, 60° and 108° for periodic inspection of measurement accuracy
The BP-D5 is a fully automatic bubble pressure tensiometer for measurement of the dynamic surface tension of aqueous surfactant solutions in a time function or at a fixed surface age. For monitoring the bubble formation, the pressure voltage waveform is displayed in real-time and bubble formation is made visible by a synchronized built-in stroboscope. Temperature-dependent measurements can also be carried out with the built-in jacket type stage and thermometer. Features - “One-click” fully automated operation - Surface tension against surface age (from 20 to 5.000 ms) chart is computed and plotted automatically - Measurement of the dynamic surface tension at a specific surface age from 20 to 1.000 ms - Real-time display of the bubble pressure waveform to monitor the conditions of the bubble generation - Extrapolation of the averaged raw data according to a method suggested by Hua &Rosen - The bubble generation from the capillary is made visible by a synchronized built-in stroboscopic lamp - Built-in jacket-type stage and platinum resistance thermometer for measurements in the range of +10 to 70℃ - Ultrasonic cleaner for cleaning the glass probes

The Triboster TSf-503 is designed for computer-controlled analysis of the static and kinetic coefficient of friction (COF). The highly versatile device, with its linear reciprocating sample stage, can be used for all kinds of samples with different shapes because fixtures can be specially designed according to the sample. The TSf-503 features the unique patented crank-shaped biaxial balance technology for accurate and reliable measurements. TSf-503 is available with a standard normal load range of 100 to 1.000 g and an optional range of 200 to 2.000 g. Measurements with different loads, speeds, contact probe geometries, measurement methods, and options allow customers to set up the instruments to meet their special needs. Features - Biaxial balance technology: Minimizing the effects of inertia and other external forces on the load cell during the measurements ensures exact and reliable results. - Two-way-measurements: Measurement of the coefficients of friction in both directions of stage travel. - Automatic contact probe lift-up function: Measurement of the coefficients of friction in only one direction of stage travel. The contact probe is lifted automatically after one stroke to avoid contact with the sample when the stage returns. - Seven measuring routines: Various measuring routines are available to ensure optimal flexibility in determining specific characteristics of the samples. Available measuring routines are: - Standard repetition: Measuring the coefficients of friction repeatedly on the same measuring area in up to 12 cycles - Continuous static friction: Measuring up to 50 data of coefficients of static friction in one stroke by the stop-and-go movement of the stage - Repetition dependency: Measuring the coefficients of friction repeatedly on the same measuring area in 100 to 10.000 cycles - Multi-sample: Measuring the coefficients of friction for different samples or different areas for one sample for easy comparison - Load-dependency: Measuring the coefficients of friction depending on different normal loads - Speed-dependency: Measuring the coefficients of friction depending on different speeds - Time-interval dependency: Analyzing the influence of adhesion on the coefficients of friction depending on up to four different contact times in one way by use of the counterpart lift-up function and the stop-and-go movement of the stage

The four models of the DMo series are high-performance contact angle meters, only differing in their grade of automation. The high-speed camera and computer controlled dispenser allow for precise measurements of static and dynamic contact angles, surface and interfacial tension of liquids as well as analysis of surface free energy of solids. A wide range of options are available and lower grade models can also be upgraded later. Features - Fast image capturing system with standard 125 fps at 640×480 resolution USB 3.0 camera, max. 333fps at 640×136 resolution - Automatic single dispenser system - 150x150mm wide sample stage with a maximum load capacity (temperature chamber + sample) of 1.4kgs - Stage travel distance: x-axis: 150mm, y-axis: 75mm, z-axis: fixed - Focusing aid with displayed index graph and value and brightness adjustment to achieve perfect focus - Movie converter to convert data images to MPEG-1 or AVI movie format - Determination of contact angles, droplet volume, residual droplet volume, sessile drop volume, height and radius of sessile drop - Measured results are displayed in a spreadsheet for easy reference and comparison, and saved in csv format for easy export to and manipulation in MS Excel - User-specified analysis report function, providing measurement results and parameters - Droplet calibration standard for standard view, bearing one full circle for calibration and three droplet silhouettes of 5°, 60° and 108° for periodic inspection of measurement accuracy

The portable contact angle meter PCA11 is a compact and lightweight device for fully automated on-site measurements of contact angle, surface tension and surface free energy of solids. Testing on-site for quality control and evaluation of surface wettability, which is characterized by the contact angle, is often required during manufacturing processes or in the field. The PCA-11 can be used on any material such as glass, metal, film, paper & pulp, polymer, wood, etc. that have to be measured on-site or that due to their size or shape cannot be analyzed with usual stationary contact angle measuring instruments. Weighing only 650g, combined with the single-click fully automated operation and its precise measurements, the PCA-11 is the ideal solution for non-destructive surface evaluations. Features - Single-click fully automated operation - Precise measurement of contact angles, even on slopes of up to 90 degrees - Analysis of surface free energy - Measurement of surface tension using the pendant drop method - Time-dependent measurements by image capture of up to 30 fps - 500 droplets with a volume of 1μl can be generated with one prepared syringe - Simple replacement of syringe and liquid sample via easily accessible front door - Visible needle tip allows precise capture of the target point - Droplet calibration standard for standard view, bearing one full circle for calibration and three droplet silhouettes of 5°, 60° and 108° for periodic inspection of measurement accuracy
