FAQ:
Q:
How to convert reading values into contact angle values?
A:
The scale reading is the contact angle value. No conversion required.

Q:
What is the correlation with the conventional contact angle meter?
A:

Q:
What is the accuracy required to choose a micropipettor?
A:
Please choose one with the accuracy of around within 5%.Click here for details.

Q:
Depending on background colors (substance color), the edge of water droplet can not be seen clealy.
A:
Please try with wetting tension test mixture ink No. 73, which has the same surface tension as water and is normally colored in blue or green.

Capillary Rise Method Dyne Gauge, DG-1

申し込み

Components:
Standard configuration:Capillary with surface tension scale (2 or 4 pcs), Teflon dish, dropper head, instruction manual, Dedicated case

Technical data:
Scale range:0 ~ 80 mN/m、 Resolution:1 mN/m

Quality:
The accuracy of the capillary rise method mainly depends on the quality and processing accuracy of the capillary. Only carefully selected and processed capillaries are used for products.

Feature:
Thanks to our inorganic material basis lyophilic coating, which is produced with highly developed sol-gel synthesis method, and our careful coating work, Surfgauge has overcome 2 main problems of complete wetting of samples and clearing of inner wall of the capillary. These 2 problems prevented the capirally rise method from being comercialised.

FAQ:
Q:
What is the accuracy?
A:
The accuracy mainly depends on the tolerance of inner diameter of the capillary. We carefully select only the capillaries which keep the accurate within +-3%.

Q:
What is the effect of viscosity?
A:
Basically, as long as the tested fluid has no yield stress it can be measured. But the greater the viscosity is, the longer the rising time becomes.

Q:
How does the inclination of the capillary during measurement affect the measurement results??
A:
No effect unless tilted beyond viewable level.

Q:
How to convert mN/m to dyne/cm?
A:
Both of the read values in mN/m and dyne/cm are the same. N (Newton) is now used as SI (International System of Units).

Q:
Measured value seems higher or lower.
A:
a) Correction for fluid density is required according to following equation:
    surface tension = read value × density
b) Be careful not to leave any residue such as cleaning solution or previously measured liquid.
c) Be careful not to contact any contaminants, directly or indirectly, with the sample, including the sample container and the parts that come into contact with the capillary. Especially in the case of water-based solution, even a slight amount of sebum greatly reduces the surface tension.
d) High surface tension tends not to reach proper height if inside the capillary completely dried. Please try pre-wetting according to the instruction manual.

Q:
Any attension for maintenace?
A:
Do not leave the capillary with tested fluid remaining inside the capillary. It or its precipitate tend to strongly bond to interior of the capillary as time passes. After using, rinse the tested fluid off under running water first and then remove the remaining water inside with acetone.

Q:
What are recommended washings?
A:
Basically, acetone and benzene. Also, alkaline cleaner solution can be used for strong contamination, but please note that its pH should be under 10.0 and below 50 dgrees. Proper washings for your samples also can be used as long as they doesn't damage glass.

A:
OK to use an ultrasonic washing machine?
Q:
Yes, but please do not avoid lengthy washing with it.

Stirring Motion Viscosity Evaluator, SVE-1

申し込み

Components:
Standard configuration:Display and control box(standard or WiFi), sensor stick(for Low or High viscosity), instruction manual
Option/accessory:Calibration tool, carrying case
*WiFi compatible model includes the browser-based loggking software

Technical data:
Measuring force:40 ~ 1600 mN、Viscosity range(approx.):50 ~ 1000 mPa・s(Low type)、500 ~ 10000 mPa・s(High type)、Measuring temperature: 0 ~ 100 ℃

Feature:
We do blending, mixing, foaming, beating, kneading, etc. in our daily lives. By feeling the flowing resistance we determine how the material is easy to mix or guess the changes of material state. The flowing resistance we feel does not come from only viscosity but also certain or uncertain other factors like postural change, stability, distortion or human habit. The SVE-1 measures "real" flowing resistance force and evaluating viscous of the fluid in human stirring motion.。

WiFi:
The SVE-1 equips WiFi module(optional), which is capable of directly transmitting to your tablets/PCs to browse, log and visualize the data.

FAQ:
Q:
How to select Type-L and Tyep-H?
A:
Tyep-L is for lower viscosity and Type-H is for higher viscosity. Estimated suitable viscosity ranges are
    Tyep-L: 50 ~ 1000 mPa・s
    Tyep-H: 500 ~ 10000 mPa・s

Q:
What can I do with the WiFi module?
A:
By directly communicating with your PC or tablet device equipped with WiFi, the logger software which is not needed to be installed starts on the browser. It is possible to visualize data and record values on the data sheet.

du Nouy Method Force Tensiometer, DRT-1

申し込み

Components:
Standard configuration:Main body, platinum ring, lab dish, level, instruction manual
Option/accessory:Platinum ring, carrying case
*A lifting device such as lab jack and a lab stand are required.

Technical data:
Measuring range:~ 200 mN/m(surface tension), -40 ~ 85℃(temperature) Resolution:0.1 mN/m(surface tension), 0.1 ℃(temperature) Dimension:80(W) x 35(H) x 165(D) mm Power supply:5V, 2A

Feature:
This is a surface tension meter based on the du Nouy method, which is one of the most typical surface tension measurement methods. By simply pulling the platinum ring away from the liquid surface, accurate surface tension values are automatically measured. The temperature of the liquid is also measured simultaneously.
