Complete Electrophysiology Teaching Unit

The two BS4 50-9513 Isolated AC/DC Preamplifiers, see page I62 for full details, are connected externally to the Electrophysiological Teaching Unit, enabling measurements such as vector cardiography. In addition, for certain experiments, two students can use the equipment at one time. The high gain, low noise and high common mode rejection make these Preamplifiers suitable for applications at the microvolt level, which is within the range of nerve and muscle potentials, ECG, EMG and EEG signals. The Preamplifiers are optically-isolated and battery-powered for maximum safety. The Audio Amplifier can be used to monitor the twin Preamplifiers’ signal. The controls on the front panel select the modulation facility and the channel to be monitored. The Transducer Interface has suitable bridge and amplifier circuits for use with Harvard Apparatus’s complete range of transducers, see right. A multi-turn potentiometer can be used to adjust the DC level. A mode selection switch matches the input to the appropriate transducer

ISOTONIC TRANSDUCER

This Transducer is exceptionally sensitive and stable,requiring a minimum of force to produce a substantial electrical signal. It usesprecesion ball bearings and graduated optical density vane that moves between an infrared source and a sensor.

The notched, pierced input lever is 90 mm (3-1/2 in) long for easy connection muscle tissue. A spring and anchor post are supplied for converting the unit in to a Transducer capable of recording frog/heart muscle tension for auxotonic applications.

Two 9.5 mm (3/8 in) stainless steel Electrodes are attached to two sheathed, stout brass wires. The wires are bound together for 92.1 mm (3-5/8 in) and then split into two leads each of which is fitted with a terminal. Each terminal has a small hole and thumbscrew that permits a wire to pass through and be secured for connection to a stimulator.

• Self-powered transducer and amplifier in one
• Transducers are available with three different sensitivities
• Each Transducer has two selectable ranges

These Research Grade Isometric and Isotonic Transducers supply excitation voltage to a self-contained transducer and convert the pico-farad changes of capacitance into high level DC voltages using a patented electronic circuit (U.S. Patent #4,142,144). This circuit is extremely sensitive and stable, producing up to 5 VDC for direct connection to Standard Signal Conditioners, Data Acquisition Systems, Modular Universal Oscillographs, Student Oscillographs, Flatbed Strip Chart Servo Recorders, and X-Y Plotters.
All transducers have a small external transducer element hard-wired to a small amplifier. This amplifier is hard-wired to a wall type transformer. The transformer reduces line voltage to 12 VDC and is both UL- and CSA-listed. For 230 VAC, 50 Hz operation the transformer is VDE-listed. These Transducers are factory-calibrated to deliver 5 VDC for full rated load and are still linear for 100% overload (4 VDC). They have offset (tare) controls.
The Transducer amplifier has a 3-digit backlit LCD display that shows the output voltage. A standard BNC output connector is located at the rear of the amplifier. These amplifiers can be stacked for multiple use. This Isometric Transducer approaches the ideal of measuring isometric contraction force without motion. It is available with three different force ranges. Each Transducer has an X10 range selector switch providing two ranges.This Transducer measures force by measuring the change in capacitance of a stiff beam between two plates. Beam deflection is measured in microns.Two models are now available. The only difference between the models is the length and diameter of the mounting rod. Model 1 has a 12.7mm OD by 51mm long mounting rod. Model 2 has a 9.5 mm OD by 91.4mm long mounting rod

CHEF DR II SYSTEM 220/240V INCL.ELECTROPHORESIS CELL, DRIVE MODULE, CONTROL MODULE, VARIABLE SPEED PUMP 14x13CM CASTING STAND WITH FRAME AND PLAT FORM

Pulsed field elecorophoresis is a technique for resolving chromosome size DNAs. Conventional electrophoresis does not pexmit resolution of DNA fragments larger than 50,000 base pairs. By alternating the: electric field between spatially distinct pairs of electrodes, DNAs on the order of 10 megabases are able to reorient and move differentially through the pores in an agarose gel.l-3

The CHEF-DR II system (Figure 1) is an advanced pulsed field system based on the CHEF (clamped homogeneous electric fields) technique.3 The key to high resolution, sharp bands, straight lanes, and reproducible separations is a uniform electric field at all points of a gel, and an optimal 120 degree angle of alternating pulses. The CHEF-DR II system accomplishes both of these by establishing the electric field along the contour of a hexagonal array of 24 electrodes. Electrodes along the sides of the hexagon are powered in such a way as to generate two different alternating electric field vectors. Each electrode “clamps” the voltage of its individual region of space as necessary to maintain field homogeneity
