Pulley for motor 472005
Pulley for motor 472005Pulley with Ø 3.2 mm centre hole that fits the axle of motor 472005.
Pulley wheel on a rod
Pulley wheel on a rodThe pulley wheel has a diameter of 50 mm and is mounted on a rod with a total length of 250 mm. The rod has a diameter of 12.5 mm, and the construction ensures that the pulley has very low friction. This makes it suitable for experiments where it is important to minimize resistance to movement.
Pulley with clamp
Pulley with clampPlastic pulley, Ø 50 mm, fitted with a clamp, for mounting on standard Ø 10 mm support posts.
Pulley with clamp
Pulley with clampThis pulley is equipped with a sleeve that allows it to be attached to rods with a diameter of 10 mm. It has a pulley wheel with a diameter of 50 mm and can be easily adjusted in height on stand rods, providing flexibility in experimental setups.
Pulley with plug
Pulley with plugThe pulley is used in acceleration experiments with the air track.The plug fits a hole in one of the ends of the air track.The mass distribution of the pulley is equivalent to an extra accelerated mass of 2.43 g.Included in 195003 Accessory set for air track.

RNA model
RNA modelThis RNA model makes it easier to study the structure. The model contains 12 bases: 3 thymine (T), 3 adenine (A), 3 guanine (G) and 3 cytosine (C) in their respective colors. The side chains consist of deoxyribose (red) and phosphate (purple), which can also be separated.
Rocket car
Rocket carRocket, stomp model
Rocket, stomp modelFoot pump rockets are a set where rockets are launched by stepping on an air cushion. The harder you step, the higher the rocket flies, which can reach up to 20 meters. The rockets are equipped with a soft rubber cap so that they can land safely without damaging the surroundings. The set comes ready to use and contains 3 rockets, ramp, hose and air cushion.
