We do not carry a clamp designed specifically for clamping the ultra pulley to the edge of a table or lab bench.
Since the parts are standard sizes, it is possible to use the Motion Detector Clamp Motion Detector Clamp (MD-CLAMP) to clamp the ultr...
The Photogate supports two configurations of the Ultra Pulley. The most common is to place a string in the groove of the pulley, as in Atwood's Machine experiments. For this configuration, set the Photogate distance calibration to In Groove.
On th...

The cuvettes we sell for our Colorimeter and the SpectroVis Plus are made of polystyrene, which can be damaged by many different types of liquid substances. Examples of common liquids that should NOT be poured into these cuvettes: ketones (acetone, ...
The Lego Digital Designer (LDD) software automatically updates itself every time you open it. Somewhere around v 3.0 Lego changed the definitions of some of the bricks and beams in the model, particularly the defined error tolerances. As a result, if...
To use the internal sensors on the WDSS to make rotational physics measurements, it is important to know exactly where the accelerometer is located inside the unit.
If the unit is face up, the sensor is located 53 mm from the edge with the force s...
To use the internal sensors on the LabQuest 2 to make rotational physics measurements, it's important to know where the accelerometer itself is located inside the unit.
If the unit is face up the sensor is located 72mm from the docking connector a...
First, we need to determine if there really is mold inside the shaft of the sensor--it might be a precipitate rather than mold. To test this, place the sensor in ~150 mL of warm water and let it sit in the warm water for 15-20 minutes. If the amount ...
Logger Pro is no longer sold and will no longer be updated.
Most consumer-level Macs include a built-in iSight camera. On these computers it is not obvious how to use an external camera, as the OS assumes you want to use the iSight.
These inst...
