Lascells
Switched Power Supply
Switched Power SupplyA traditional switched power supply which uses established PSU technology to provide a smoothed power supply suitable for all laboratory applications which require a rugged source of emf at either AC or DC.
Thermal System Aluminium
Thermal System AluminiumThis new approach to measuring Specific Heat Capacity provides a self-contained apparatus to replace the traditional metal blocks and immersion heaters. A 300 g aluminium block (brass and steel also available) is mounted on an insulating base with a heating element attached to the underside. The block has a 4mm hole for data-logging probes, thermometer hole and felt insulating jacket. The heater is 30 W at 12 V and requires a standard laboratory power supply to provide up to 3 A. Typical temperature rises are 40 C in 5 minutes providing a convenient investigation for students using thermometers and stopwatches as well as computer based data systems. Full instructions and theory included.

Thermistor System
Thermistor SystemThis apparatus contains an NTC bead thermistor with a nominal resistance of 4.7kΩ in a glass tube with electrical connection made by means of 4mm flying leads.
Timer Light Gate
Timer Light GateAn infra-red beam, high speed light gate for use with Lascells timers. The attached cable is terminated by a 3.5mm jack plug which fits directly into the timer so that no other connections are required.
Trans-Ratio
Trans-RatioTrans-Ratio is a fully self-contained transformer system which enables students to investigate turns ratios and efficiency with the minimum of complication.
Triple Timer
Triple TimerThe Lascells Millisecond Triple Timer provides all the facilities required for dynamics timing. The three modes of operation are activated by START and STOP switch contacts (4mm sockets) or by using Lascells Light Gates which plug in directly, hence requiring no additional power supplies.
UV Test Rig
UV Test RigA UV LED provides the UV source in this test rig. Because of its construction there is no radiation hazard and students can test the UV absorbing properties of various materials.
Vacuum Bazooka
Vacuum BazookaThis amazing device attaches to a vacuum cleaner and launches lightweight, hollow projectiles at high velocity.
When aimed vertically typical heights reached are 5 to 6 metres. Additional weights can be added to the projectiles for all manner of investigations into energy, acceleration, momentum etc. An essential item to brighten up the subject of dynamics or to amaze everyone on open days and science fairs.
As featured in the book “Vacuum Bazookas and Electric Rainbow Jelly” by Neil Downie.
Velocity of Sound
Velocity of SoundThis apparatus provides a test bed for investigations into the characteristics of sound waves. A sensitive microphone on a linear scale allows for measurements to be taken along the path of the wave emanating from a small loudspeaker acting as the sound generator.
Viscosity Kit
Viscosity KitThe kit comprises a 1m long, 50mm diameter acrylic tube, fitted with two rubber bungs and supplied with five nitrile O-rings on the outside.
Wheel and Axle
Wheel and AxleA pair of coupled solid Acrylic wheels 150mm and 50mm dia on a freely running bearing supported on an aluminium handle suitable for holding in a standard laboratory clamp. Threads can be attached so that mechanical advantage and velocity ratio can be measured.
Wind Generator
Wind GeneratorA low inertia electric motor with plastic impeller. The impeller can be rotated using a hair drier or blower and a DC voltage can be monitored at the output. The output can be used to illuminate an LED, to demonstrate energy transfer or the system can be used as the basis of an investigation linked to renewable energy sources.
Wireless Rubens Tube Amplifier
Wireless Rubens Tube AmplifierThe Lascells Wireless Rubens Tube Amplifier allows users to wirelessly connect audio sources to their Lascells Rubens Tubes.
Zinc Plate
Zinc PlateA 40 × 40mm zinc plate on a 4mm connector which can replace the top plate of an electroscope.
The plate can be used to show discharge under UV Lighting and the photo-electric effect.
