Panlab proposes two multi-channel digital thermometer models suitable for the measurement of animal body temperature using rectal probes. Both systems are designed for working with up to 12 resistive-temperature probes simultaneously.

Temperature is measured by using Yellow Springs (YSI) thermistor and the registered current value shown in the digital display of the front panel with a resolution of 0.1 degrees (sensitivity range: 32-45°C). There is no difference between channels or temperature probes, freely interchangeable. Standard YSI temperature probes should be plugged in the jack connectors of the rear panel, while the temperature value is read from the front panel display.

TMP812 model allows the reading of the current temperature of one channel at once. The selection is done by switching the desired channel in the 12-positions front panel rotary commuter.

TMP812RS model offers a 20x4 LCD display for showing the current temperature of all the probes at the same time. A built-in RS 232/USB communication port, allows sending (by pressing a front panel “SEND” button) the temperature values from all the probes to an external device (matrix printer with serial port or PC computer) through the SEDACOM software.

The new SEDACOM 2.0 version provides an easy and convenient way to visualize and export the data on a computer for further analysis.

The PANLAB Coupler Module ISO510A is an Amplifier for bridge-system designed to work with a wide range of different transducers for evaluating pressure, strength or respiration in various research areas. As an example, the ISO510 model is currently associated with the isometric or isotonic transducers for the study of in vitro tissues preparations using Organ Baths.

The PANLAB ISO510A Amplifier can work in both AC and DC and amplifies signal up to 2.000 times. The Amplifier contains a filter allowing the suppression of the noise produced by electrical or mechanical artefacts associated with the experiment running (for instance, ventilation and heating pump systems in Organ Baths) and then eliminates vibrations that may affect the signal received from the biological preparations. A Transducer Balance option allows a fine adjustment of the signal baseline (“zero”) when the transducer is not excited by the variable to be measured. The ISO510A amplifier also allows the external monitoring of its output signal, for instance to an oscilloscope…

The ISO510A Amplifier is available in two versions: individual Amplifiers accompanied with the corresponding external Power Supply Box or individual Amplifiers integrated into the Power Supply Box.

Key features

• High Gain Differential AC/DC Amplifier
• Includes a filter allowing the suppression of background noise
• A Transducer Balance allows a fine adjustment of the signal baseline
• Allows external monitoring of its output signal

Panlab provides complete hardware solutions and associated software for isolated tissues studies from simple, manual systems to automated, computer-controlled systems. 

The mechanical activity of the tissues (muscles) is formed by a displacement (elongation) and a force (contraction). The ratio between elongation and force depends on the properties of the tissue under study: some tissues exhibit a mechanical response with a very large displacement and a reduced force; other tissues produce short but very intense contractions (in terms of strength). Depending on this ratio, the transducer used for performing an organ bath experiment will be isometric or isotonic.

- Isometric transducers

The Panlab Force/Isometric Transducers measures the force of contraction of isolated tissues under conditions of constant force. 

Isometric force transducers are very sensitive to the force applied under conditions contraction with very short amplitude (low displacement). As an example, the Transducers of weight of the electronic scales acts in an isometric way. Generally the isometric technology is also used to measure frequencies; for this reason, the displacement of the sensor of the transducer need to be as slight as possible. Panlab has transducers with a minimum displacement of 0.1 mm for a force application until 25 grams.

Isometric Transducers are classically used in Organ Bath experiments with muscles with short/rapid contractions such as tracheal muscle, atrium, papillary muscle, aortic rings, veins or other vessel rings.

The Transducers are equipped with a special system allowing an easy and rapid fixation of the thread that tightens upper side of the tissue in an organ bath. Panlab provides transducer for various load range, from teaching to standard research systems.

- Isotonic transducers

The Panlab Isotonic Transducer measures displacements with pre-adjusted loads (position transducer).

Isotonic transducers are classically used for measuring the contraction amplitude of isolated muscles in Organ Bath studies, i.e. the changes in tissue length observed under a constant load.

To achieve this capacity, an isotonic transducer must possess a sensor axis which rotates at least 25 degrees. This type of register was the one which was used initially, at the time of the kymographs in such a way that the transducer was configured by a lever, balancing on a pivot.

These transducers are preferably used with smooth muscle preparations characterized by relatively slow contractions (ileum, vas deferens, lung strips, esophagus, urinary bladder, etc.).

Which transducer? The Panlab advice.

Although in principle and from the physiological point of view, the most appropriate for smooth musculature is the isotonic and for heart and striate the isometric, in purity all animal muscle contracts partly isotonically and partly isometrically. Nowadays all the tasks are done with isometric as the response is much more repetitive, the basal line is much more constant, and the relaxation much more rapid. Isotonic transducers are only used in few specific cases
