The polypropylene Buchner funnels are two-piece, lightweight, and easy-to-clean. The top portion snaps into the bottom forming a vacuum tight seal. The funnel has an opening with an inside diameter of 90mm. And they are fully autoclavable.

These color filters are made of acrylic and contain five different colors: red, green, yellow, orange, and blue. They are durable at 1/8" thick and can be used to assist in many optical experiments such as attenuation of laser beams and optical transmission measurements, and color mixing.

The angles of incident and refractive rays are easy to see with the help of a built-in laser. The water that is added to the tank provides a surface for reflecting the laser light. The laser light can be positioned and fixed at any point around the graduated circle. The prisms and mirrors…

A Fresnel lens is a compact type of lens which was first used in lighthouses. The construction of these lenses allows for a large aperture and a short focal length without the mass that would normally be required. This small pocket size Fresnel lens is 85mm x 55mm and is provided with a cover. It…
