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.

Refill for simulate blood type set (FR-780080)
Refill for simulate blood type set (FR-780080)Refill for blood typing kit AB0-Rh with simulated blood (item number FR-780080) contains the fluids necessary to perform multiple blood typing tests without using real blood. The refill kit consists of four types of simulated blood (7 mL each), as well as simulated Anti-A, Anti-B and Anti-Rh serum (7 mL each). The simulated blood is made with colored particles that react with sera in a clear and visual agglutination process.
