Surface Tensiometer:

The measuring methods used in Kyowa surface tensiometer are the Wilhelmy plate method, du Noüy ring method, pendant drop method, and maximum bubble pressure method.The Dyne Master tensiometer series starts with model DY-300 and the most sophisticated model is the DY-700. 

DY-300:

When interfacial tension is measured, the system is delivered with du Noüyring and a bigger sample receptacle with graduation. Operation can be done using either the right or left hand, and the cell can be viewed during measurement.The light weight allows operators to conduct experiments without much effort. Viscous liquidsup to 2000 mPa?s can be measured.

Displays: Density - Temperature compensated density and specific gravity - Percentage of Brix - Alcohol concentration - Sulfuric acid concentration - API degree - Baume degree– Plato - Proof degree

Graphic LCD display: Temperature - Sample number - Auto sensing oscillation stability - Auto data saving - Auto data output - Data deletion - Battery capacity

The life of battery is twice that of conventional makes and results in much longer operation time.The sampling volume and speed are to be controlled using a single hand.

Features:

(i) The pre-wetting function eliminates measurement errors caused by unsuccessful wetting of plate.

(ii) Applicable for surface tension measurements of liquid samples with a volume as small as 1mL with optional 1cc lab dish.

(iii) Ideal for Quality Control purposes with the repetitive measurement function.

(iv) Lamella length measurements and du Noüy Ring method with a platinum ring.

(v) Measurement of liquid density and sedimentation behavior with optional kits.

(vi) Temperature dependent measurements (optional with temperature control stages and peripheral devices)

Kyowa Interface, Japan have been manufacturing contact angle meters since 1960.The contact angle meter also goes by the name goniometer. These instruments are used in contact angle measurement, surface free energy analysis, and surface or interfacial tension measurement.

DMe-211 are economical yet fully-featured contact angle meters with computer image analysis system "FAMAS" software enables automatic analysis of contact angle. The upper grade model DMe-211 enables measurements of surface/interfacial tension by pendant drop method as well.

Analysis of surface free energy is possible with optional add-in software.

FEATURES:

• Possesses “Droplet-trans detection” and enables variation over time in 1FPS.(DMe-211 only)
• Stage up/down motion enables gentle deposition of droplet without distorting it.
• Level of body and stage are adjustable. This is significant for measuring hydrophobic surfaces.
• Standard droplet sample is attached for periodic inspection and calibration.
• LED light source is used to eliminate temperature effect to the measurements.

STANDARD COMPONENTS:

• DMe-211 main body
• Dispenser
• Set of 5 glass syringes and 22G SUS needles
• Standard droplet sample (standard view)
