POWER SUPPLY VAR 'DUAL MODE' REG & SW V/A DIGITAL METER This very popular IEC "Dual Mode" Power Supply combines both AC/DC switched and DC smooth and regulated power outputs. It is suitable for both general lab work and electronic studies where a smooth and regulated output is necessary. Overload protection is automatic for both modes of operation. The meter on the regulated section can be switched to monitor either output... more info

POWER SUPPLY 'DIGI-PAK' 2-12V SW & 1-16V REG DIGITAL METER   An advancement to the "school workhorse" LB2633-001 Power Supply. This unit has the same outputs as the beloved LB2633-001 but, in addition, it provides a regulated DC output up to 16V.DC. and up to 3 amp max. This regulated output is SMOOTH DC and is monitored by a red LED digital display. Electronic experiments almost always require a smooth DC supply (like... more info

The IEC Very Low Frequency Oscillator provides a sine wave output of 0.1Hz. This means that it takes 10 seconds for the sine wave output to complete one full sine wave cycle. Output is 15V peak to peak and output current is up to 5mA. Accuracy of frequency is about +-5%. A press button will stop the oscillation and hold the output at 7.5V. This feature allows the oscillator to synchronise with an event. Can be used for study of phase of volts... more info

The IEC digital Electrometer is a special instrument for measuring extremely small quantities of voltage, current and charge. The ranges are: 0-2, -20, -200, -2,000 mV with very high impedance. 0-2, -20, -200, -2,000nA (nanoamps) with very high impedance. 0-2,000nC (nanocoulombs) of electric charge. Used for measuring electrostatic charges, currents passing through an insulator, charge around an electrostatic rod, capacitor charging and... more info

The cellulose nitrate (CN) or also called mixed cellulose ester (MCE) membrane filters are composed of cellulose nitrate and a small content of cellulose acetate. They are recommended for a broad range of applications like the filtration of aqueous solutions or for sample preparation. Cellulose nitrate (CN) - or mixed cellulose ester (MCE) - membrane filters are composed of cellulose nitrate and a small content of cellulose acetate. Cellulose... more info
