Tensiometer TD 2
Applications & Advantages TD 2
The LAUDA Tensiometer TD 2 is used to measure surface and interfacial tension, to determine the density of liquids and to measure small weights. The fully-automatic and cost-effective
instrument consists of a precise electromagnetic weighing cell plus a remote control panel with a userfriendly graphic LCD- screen for precise measurements.
Fully automatic yet simple and precise
New Measuring Options
The successor to the TD 2 accomplishes the move to fully auto- mated tensiometry and maximises user convenience directly over a PC. This extremely compact stand-alone device offers everything needed to measure surface and interfacial tension at the push of a button either in the laboratory or in the field as simply as possible. The accurate, reproducible results can be displayed, printed, saved, or transferred to a PC. With this devi- ce it is also possible to measure the density of liquids and to de- termine small weights. The convenient external control panel has a large graphic display that can be operated intuitively with- out special training. The integrated microprocessor handles sample positioning, force maximum detection, and data correc-
tion. The program repeats measurements until a user-defined stability is reached and calculates static surface/interface tensi- on and standard deviation over the last series of individual mea- surements, and compiles the results in easy-to-understand ta- bular format.
➢ High resolution (± 0.01 mN/m, ± 0.1 mg) and expanded measuring range up to 300 mN/m up to 5 g
➢ Automatic maximum detection and maximum scanning with selectable range
➢ Tabular representation of individual measurements, number of measuring points, measuring time, corrected and
Advantages TD 2
The LAUDA Tensiometer TD 2 is easy-to-operate and supplies surface and interfacial tension of liquids at the touch of a button. It is therefore particularly suitable for beginners and for education. Surface and interfacial tension values are displayed digitally. The selection of measuring methods is simple and calibration is implemented using standard weights.

Application options
There are numerous applications for the LAUDA Tensiometer TD 2. It is used for example to determine and test physical properties of solutions, organic and inorganic liquids, liquid/liquid or liquid/solid dispersions, emulsions, etc. or to develop and test surface ac- tive substances such as surfactants and emulsifiers and to identify the such substances in effluents and in waters.
Measuring stand
Example: Control of cleaning water
The measuring stand is equipped with a high-resolution load cell and a DC motor for smooth movement of the measuring table with 10 sel- ectable speeds. A temperature sensor and magnetic stirrer can be connected to the device on request. The accessible sample chamber allows the use of standard sample beakers up to 8 cm in diameter.
Surfactant traces left from cleaning agents can negatively affect foam formation, e.g. in beers, and must be prevented. A surfactant analysis would take too much time and would be too expensive.
Solution: It can be determined whether traces of surfactant are present in the rinsing water by measuring the surface tension with the TD 2, e.g. using the ring method, and then comparing it with that of pure water.
With its rugged design, ease of operation, and high precision, the TD 2 is ideal for use in all quality control applications. Since measurements are taken completely independently by the user and documented together with the required settings, the device also meets the stringent requirements of the GLP guidelines.
uncorrected data (surface/interfacial tension, density)
➢ Automatic ring correction (based on Zuidema and Waters)
➢ Automatic control of data stability based on predefined standard deviation
➢ Semiautomatic calibration in three accuracies with standard weights
➢ Input of ring/plate geometry possible
➢ User-defined measuring point density and measuring time
➢ Storage of up to 500 measurements with related parameters
➢ Numerical user-defined sample designation
➢ Direct or subsequent output of data to optional printer or PC (optional data transfer program required) via RS 232 interface ➢ Measurement and documentation of temperature in the sample by means of digital temperature sensor (optional)
➢ Magnetic stirrer control for homogenisation of disperse samples

Basic components:
This convenient control panel allows the complete remote operation of the measuring stand (movement of sample table, input of measuring parameters, start of measurement, and transfer of data over RS 232 interface to printer or PC). This minimises vibrati- ons to the measuring stand. The high-resolution graphic display offers menu-based user guidance and displays individual measu- rements and results in tabular format.
