Lascells
Ripple Tank MkIII
Ripple Tank MkIIIThis compact unit provides an elegant method of demonstrating the wave phenomena of reflection, diffraction, refraction and interference with none of the setting-up problems usually associated with ripple tanks. The concept has been further developed to offer new features and simplicity in this MkIII design.
Rotary System
Rotary SystemThis simple but effective system makes a complicated topic into one of the most enjoyable lessons possible for all ages at secondary level.
It allows students to easily investigate the forces of circular motion so that they get hands-on experience of the effects.
Rotary Table
Rotary TableA strong turntable suitable for rotational motion demonstrations.
Rubens Tube
Rubens TubeA truly exciting way to show the effect of sound waves in action, the Rubens Tube really brings the topic to life in a way the students will never forget. The robust stainless steel welded construction means trouble free operation for many many years.
Search Coil
Search CoilA 3300 turn, 25mm diameter coil on a plastic handle for investigating changing magnetic fields.
Slide Carrier
Slide CarrierA simple acrylic carrier to hold standard slides 50 x 50 x 2mm such as Young’s slits
Product code: LA20-882
Space Tube
Space TubeA modern replacement for the Bell in a Bell Jar Apparatus. A 90mm diameter acrylic tube houses a battery-operated, high output piezo sounder.
Spare Tube For Polarimeter
Spare Tube For PolarimeterA flat bottomed glass tube of the type used in the Student Polarimeter
Spectral Source
Spectral SourceThis unique unit has been specially developed to provide a varied range of light sources for examination by spectrometers.
Speed of Sound
Speed of SoundThis is an easy to use piece of apparatus for determining the speed of sound in air.
The unit contains two sensitive microphones connected to control circuity that will start and stop a Lascells millisecond or microsecond timer. Alternatively the outputs may be monitored on a storage or pc oscilloscope.
Splat The Rat
Splat The RatFun and dramatic demonstration of Lenz’s Law. Interactive and entertaining demonstration of induced currents and magnetic fields. Lenz’s Law can be demonstrated using the standard Eddy Current Tubes whereby a magnet falls through a copper tube at a slower rate than an un-magnetised weight.
Static Cell
Static CellWhen insulating materials rub together, electrons transfer from one to the other and, since the charge cannot be conducted away, the charge is retained on the surface.
Stationary Wave Apparatus
Stationary Wave ApparatusCompletely self-contained and ready to use at a moment’s notice with minimal setting-up required. Just connect a laboratory signal generator (not included) to the 4mm sockets of the integral vibration transducer, adjust the tension in the string to the required value by sliding the spring balance assembly and away you go.
Stress Structure Set
Stress Structure SetA set of four additional shapes for use with the polaroid analyser and a sheet of material 200 × 200 × 2mm from which other shapes may be cut.
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.
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.
