The Lascells E-Field Detector provides a new and novel way to demonstrate charge. This highly sensitive electronic device is an essential piece of equipment in the Physics teachers’ armoury as it can detect very small charges and their polarity, as well as charge at a distance. Until now, in the school science lab, it has only been possible to demonstrate opposite and like charges by repulsion and attraction experiments or the very delicate Gold Leaf Electroscope. This unique, robust piece of equipment allows the Physics teacher to clearly show whether a positive or negative charge has been created and in which directions the electrons have moved. The LED array indicates not only positive or negative charge, but also its size. The external voltmeter sockets allow for quantitative measurements. Very quick and easy to setup, the Lascells E-Field Detector is a benefit for specialist and non-specialist teachers alike and is so easy to use that students could gather data themselves. The comprehensive instructions include both traditional experiments that benefit from the use of the Lascells E-field Detector along with new exciting ways to look at charge. This makes difficult concepts more understandable and engaging for the students. This is a real game changer in the subject of electrostatics. 24V AC-DC Adapter included.

The Proof Plane is a device for transferring charge from a charged object. Charge a plastic strip by rubbing with a cloth. Touch the charged object with the proof plane. Charge will be shared between the object and the Proof Plane so both will have the same charge sign. Show this using the E-Field Detector (EL220000) If you are using a Faraday’s Pail touch the inside of the Pail with the charged Proof Plane. Charge will be transferred and immediately move to the outside of the Pail. If the process is repeated equal amounts of charge will be transferred each time. If the Proof Plane is charged by induction the charge sign will be opposite and usually greater than by simple charge sharing. Show these effects using the E-Field Detector.

The Earth Grounding Plate is designed for use with The Lascells E-Field Detector but can also be used in any situation where an earthed working surface is required to neutralise electrostatic charge. Place the Grounding Plate on the bench with the E-Field Detector on top. Using the detector Earth Lead connect the green Earth socket on the detector to the metal screw on the grounding plate. Use a connecting lead to also connect from the green Earth socket to a suitable Earth point such as a metal water pipe or similar.

The Charge Separation Rods are designed for use with the Lascells E-Field Detector (EL220000). Arrange the rods so that they are touching along an axis. Bring a charged object near one end of the rods and use a pencil or similar to slide the rods apart touching only the feet and not the metal part of the rods. When the charged object is removed test the charge on the two separated rods. If the charged object is negative, electrons are repelled to the rod furthest away leaving the rod closest to the object positively charged. By moving the rods apart the electrons cannot return so the furthest has an overall negative charge and the nearest an equivalent positive charge.

Mini Thermo-Anemometer

This carbon dioxide detector measures CO2, air temperature and humidity. A useful tool to help to regulate ventilation in enclosed spaces such as classrooms, indicating when fresh air should be allowed in to help remove air that contains virus particles and to help prevent the spread of Covid-19. People exhale carbon dioxide when they breath out. If there is a build-up of this in an area it can indicate that ventilation needs improving. This device adopts a high-precision non-dispersive infrared CO2 sensor that detects CO2 accurately and sensitively. Containing a high-capacity rechargeable lithium battery, making it easily portable. To preserve electricity, it powers off after 30 minutes of inactivity. A USB charging cable is also provided allowing simple recharging using either a PC or mains plug. Product specifications: CO2 concentration measurement; •Range: 0 to 9999ppm •Accuracy: +/-75ppm / +/-5% of rdg •Resolution: 1ppm Temperature and humidity detection; •Temperature range: -20 to +70°C •Temperature accuracy: +/-2°C •Temperature resolution: 0.1°C •Humidity range: 0 to 100%RH •Humidity accuracy: +/- 3.5%RH (20 to 80%RH) otherwise +/-5%RH •Humidity resolution: 0.1%RH Battery: 1000mAh rechargeable lithium battery Battery charge: USB 5V charging Dimensions: 90mm x 60mm x 47mm LCD dimensions: 49mm x 38mm Operating conditions: 0 to +50°C

Observe living creatures in this ventilated viewing pot with 5x magnification lid. Clear base with micro ruler.

These Pooters are designed not to be perfectly round so that bugs will find a crevice to hide in and are easier to observe. The jar contains two holes; one of which has a fine mesh covering to prevent bugs being drawn into the mouth. Two lengths of tubing (removable for easy washing) are supplied.

Use in conjunction with an accurate millisecond timer to calculate acceleration due to gravity. The timer starts when the ball bearing is released from the release unit, the base has an integral vibration sensor which stops the clock as the ball bearing hits the impact plate. Replace the ball bearing, reset the timer and the unit is ready to go again. When used with Lascells timers or other models with de-bounced inputs no additional power is required. If the timer used is found to have “bouncy” inputs then a 4 second delay can be added to the impact plate outputs by powering the unit with 9 V DC. Supplied with: Full instructions Base, release unit, 12 mm ball bearing, 8 mm ball bearing Features: Easy setup with integral vibration sensor No power required for millisecond timers with de-bounced inputs Two ball bearings allowing comparison of different masses Over-moulded rubber landing plate. Integrated de-bounce circuitry to add 4 second delay to outputs. (9 V DC required)

The Lascells Millisecond Timer is a fully functional, easy to use millisecond timer and has a clear, 4 digit LED display. Three sockets provide START and STOP inputs which respond to any change of switch settings i.e. normally closed to open or vice versa making triggering very simple and reliable. A single switch changes the timer from GATE 1 start and stop to GATE 1 start GATE 2 stop. In addition 3.5 mm sockets are provided to allow Lascells timer light gates to be connected. The timer has millisecond resolution for times up to 10 seconds and then the display auto-ranges for longer periods up to 9999s with corresponding reduced resolution. Supplied with mains plug-top adaptor and full instructions.

The Lascells Cloud Chamber is the perfect alternative to existing unreliable and time consuming dry ice variants. The chamber is self-contained and thermoelectrically cooled. The chamber requires no dry ice or water; the only setup necessary is the addition of isopropyl alcohol and connection to a mains socket. The chamber contains an integrated power supply and illumination of the chamber is provided by a high intensity LED. Using the provided source, tracks should be visible within 10 minutes. Once running the cloud chamber can be made to run for extended periods by adding more alcohol through the access provided in the lid.
