Driven by an electric motor working on 220 – 240 V mains, with a separate discharging sphere mounted on rod. Giving a spark of approx 3 – 4 inch. Supplied with standard accessories.

The enamelled wire winding and a cylindrical soft iron core are built into this unit. The iron core displacement inside the winding can manually adjusted by the knob to give precise measurements up to 1.3 H. Connections are made through 4 mm sockets.

Specifications:
Resistivity: 0.0165 W/m;
Inductance: 0.15 to 1.3 H;
Voltage: 30 V AC or 60 V DC.

FEATURES
Constructed of high quality plastic and combined with stainless steel piston for many years of dependable service.

• Individually calibrated as per procedure laid down in ISO 8655 standards, a calibration report is provided with each pipette.
• Built-in, streamlined tip ejector facilitates easy tip ejection and access to narrow necked bottles and tubes.
• New body design provide improved ergonomy for more comfort and less fatigue during operation.
• User adjustment (re-calibration) can be performed easily.
• Easy volume adjustment by turning the plunger even when wearing gloves. Plunger does not snag gloves.
• Nine volume ranges cover the complete pipetting range from 0.2 µl to 10 ml offering a wide choice to select the most suitable model for any application.

This dual purpose apparatus provides a compact facility for the measurement of the velocity of sound in air and also for the analysis of standing waves. It requires an audio signal generator and a dual beam oscilloscope (not included). A phase measurement between the speaker and microphone signals is made on an oscilloscope. The distance required to traverse through a 360° phase shift is noted. Knowing the frequency and distance, the speed of sound is computed. With the reflector in place a standing wave can be generated. Nodes and antinodes can easily be seen from the amplitude variations on the CRO.
