Inverted Microscopes
ACCU-SCOPE inverted microscopes deliver excellent ergonomics, top quality optics, crisp images and configurability to meet your needs. The “workhorse of the tissue culture lab,” the inverted microscope is found in practically all tissue culture rooms and is used to observe cells in culture for their health and growing condition. Living cell cultures are essential to the discovery of cellular processes, providing scientists insight into mechanisms of disease that can be used for identifying new therapeutics. ACCU-SCOPE inverted microscopes are commonly equipped with phase contrast components for the observation of living cells in culture without the need for staining. Other available contrast methods may include brightfield, fluorescence, emboss, differential interference (“DIC”) and modulation.

Variable Transformer DC Power Supplies
Variable DC power supplies are AC to DC power supplies with a variable DC output. The output can be varied with a Variable Transformer (also known as variac). The Variable Transformer can be adjusted manually or with a motorized control. The AC input power can be single phase or three phases. With single phase AC input, the DC output ripple is very high (50%). With three phase AC input, the DC output ripple is low (5%). This would be a key benefit for selecting three phase AC input instead of single phase.

Audio Generator
AG-51
The AG-51 Audio Generator contains a low distortion 20 Hz to 200 kHz sine wave generator, an SMPTE standard intermodulation signal generator and a fixed frequency sine wave generator at 3.15 kHz for wow and flutter tests. Signal outputs are simultaneously available at levels of up to +20 dBm (equivalent sine wave power for complex signals) at separate left (L OUT) and right (R OUT) output connectors. Outputs may be selected for left (L) only, right (R) only, left and right in phase (L+R), and left and right in phase opposition (L-R). Fully balanced or unbalanced outputs at impedance levels 150 ohms or 600 ohms are front panel selectable. Three precision attenuators (10, 1.0 and 0.1 dB) provide a dynamic range of 99.9 dB in 0.1 dB steps. Attenuator dials display the output level directly in dBm in the 150 ohm source impedance configuration. Automatic output leveling circuitry with a built-in self-test feature provides a constant output level thereby eliminating the need for output metering. In the TEST mode the generator output level is reduced to zero, a useful feature during noise measurements.

Three-Phase Transformer Demagnetizer
DEM60C
After a DC current test, such as winding resistance measurement, the magnetic core of a power or instrument transformer may be magnetized (remnant magnetism). It can cause various problems such as wrong diagnostics, inaccurate measurements on a transformer, inrush current at the start-up of a power transformer, or incorrect operation of protective relays due to magnetized CT cores. The best way to eliminate this source of potential problems is to use demagnetizer on the power or instrument transformer.The DEM60C is a fully automatic test instrument which performs three-phase transformer demagnetization. Transformer magnetic core demagnetization requires the application of AC current with magnitude decreasing to zero. DEM60C provides this AC current by internally changing the polarity of a controlled DC current. During the demagnetization process, the instrument supplies the current at decreasing magnitude for each step, following a proprietary algorithm. It can demagnetize single-phase and three-phase power transformers.The instrument can be connected to all three phases of a power transformer to be demagnetized, on either the primary or the secondary side. If a user selects specific vector diagrams for different types of transformers, DEM60C will run a specific demagnetization procedure for each transformer type (i.e., single phase, delta, wye/star, zig-zag.) without switching the test leads.DEM60C enables safe and efficient power transformer demagnetization. The instrument automatically regulates the injection of current and discharging energy from the inductance. During and after the operation, an intrinsically safe discharge circuit with an indicator rapidly dissipates the stored magnetic energy. The discharging circuit is independent of the power supply, which improves its reliability in case of loss of power.Test currents of up to 60 A DC enable efficient demagnetization of even the largest power transformers. Using a DV Win software, it is possible to control DEM60C externally.
