Provide a New Perspective on the Solar System

The Heliostar 76 mm H-Alpha solar telescope brings a new light to the Skywatcher family by offering a dedicated Hydrogen-alpha (Hα) solar telescope to the lineup.

Calculators feature arithmetic functions (add, subtract, multiply, divide), percent, three-key memory, and floating decimal point.

Molded in One Piece to Withstand a Vacuum up to 30" Hg.

Filtering flasks are constructed of heavy wall borosilicate glass in order to withstand high vacuum applications.

Utilize solar energy to power your design.

Pack of two filter flasks with heavy walls and integral side arm made of borosilicate glass.

What is the Big Bang Theory? How was our solar system created?

Autoclavable.

Explore solar energy with this innovative science kit designed to help students investigate energy transformations. A hinged box helps students discover how the angle of photovoltaic panels relative to the sun affects power output. Compare your experimental findings to online sun-angle calculators.

Clearly shows the path of the sun at any latitude during any month of the year.

Designed for analyzing particulate contamination of hydraulic fluids and oils using gravimetric or particulate counting methods, and can be used in exfoliative cytology applications.

The glass filter paper is excellent for microwave testing where temperatures get very high such as for use in a food experiment where all the moisture is microwaved out to see how much solid is left behind. Withstands temperatures to 500 °C. Size of each: 11 cm diameter.

The HOBO® Solar radiation shield is designed for temperature and relative humidity measurement accuracy in locations exposed to direct or reflected sunlight.

Build a solar-powered race car to explore renewable energy and motion.

This simple device gives a graphic demonstration of the sun’s radiative energy.
