"solar filter"

Improves visibility in sodium and potassium flame tests.

Our high-quality borosilicate filtering flasks meet ASTM standards.

Buchner filtering flasks are made of high quality, heavy duty borosilicate glass.

Explore how solar power is converted into motion with a solar bug.

Useful for adding powder chemical to reaction vessels.

These Polypropylene Funnels are chemical and acid resistant and can be sterilized. These funnels are offered in four different diameters/capacities to meet all your funneling needs.

Funnels are made of durable plastic. Funnels of top inner diameter 70-108 are polypropylene and autoclavable. Funnels with top inner diameter of 127 and 165 are polyethylene and not autoclavable.

The 165 mm size has a wide stem for quick transfers.

Stainless steel funnel within air channel for smooth flow.

For Use With Solar Cell.

Developed in collaboration with a science teacher from Pennsylvania, our build your own solar LED Jar light is a fun and creative way to teach and learn about solar electricity. Use your own mason jar or recycled jar and build a colorful LED light that automatically comes on at night and goes off at dawn. Comes with everything you need. This kit requires soldering. Tools needed are soldering iron, solder & flux, hot glue gun, electric drill, 3V 70mA Polycrystalline Solar Panel, Dusk/dawn circuit board, 2 Bright 5mm LED's BLUE, 2 AAA NiMH rechargeable batteries & Battery holder and wires.
A portion of the proceeds from the sales of this kit are being donated to help provide solar lighting solutions to disadvantaged communities in Africa.

Use the solar radiation shield with HOBO external sensors for improved temperature measurement accuracy in locations exposed to sunlight.

Photocells with included connecting wires

With this collection of science kits, you and your students can explore the concepts behind and the many applications of solar hydrogen, direct methanol, and other fuel cell technologies.

Economical and effective.
