Diffraction Apparatus, Used to map light intensity versus position for many-slit geometries, Slits are made by depositing metal film on glass, creating extraordinarily clean slits with fully opaque blocking areas.
Digital Control Unit, combined with features in Logger Pro, makes control of electrical devices, such as buzzers, lights, motors, pumps, and relays, both straightforward and flexible. The DCU is a great way to introduce hands-on STEM
Digital Luxmeter, economical solution for light measurements in a learning situations, the autoranging feature makes a one-button-and-done instrument, auto power-off conserves battery power, and other functions include MAX, MIN, and HOLD, Requires a 9V battery (not included)
Digital Multimeter P3340, For universal use in measuring voltage, current, resistance, frequency, capacitance, temperature, diode and continuity tests, voltage: 9 V battery, Dimensions: 92x195x38 mm3, Weight: 200 g
Disposable Bacterial Filter, disposable microbacterial filter significantly reduces need to sterilize your spirometers flow head, 30 mm ID opening allows for an easy, air-tight fit to the flow head
