Heeft levertijd

This one-of-a-kind arrangement features the detailed information you would expect from a Periodic Table, including name, atomic weight, number, and abbreviation. However, what makes this table shine above the rest are the real-life samples enclosed under each of the elements represented. All that is missing are the radioactive and otherwise dangerous elements, of course.

Key Features:

Clear acrylic casing.
Measurements: 150 x 113 x 20 mm
Real samples mounted with each element name.
Features all standard information expected.
Ideal gift for scientists, teachers, or other element enthusiasts.
Comes with a gift box and cleaning wipe for easy care.

Element Set

Bestel

Introduction to the elements with the Element Set. Large enough to examine and safe to handle, these samples provide a fascinating glimpse of the elements your students will not forget and that no textbook or photograph can match. Each element comes with an informative and durable card describing its scientific properties, commercial uses, and other interesting facts. Each set contains one sample of aluminum, bismuth, carbon, copper, iron, silicon, sulfur, tin, and zinc, and one copy of the Chemistry Reference Chart.
