What Sets Us Apart

There are countless Chinese knock-offs of our periodic tables, but they are very poor quality. The majority of these periodic table knock-offs do not contain actual elements, which is perhaps the most important feature of the display! Superior optical clarity, careful placement of the elements in the artwork, and real, pure elements are what set us apart. This is the highest quality and most complete element collection on the market. We manufacture our periodic tables here in the US using Lucite acrylic which does not yellow over time and is the most optically clear acrylic. This is the perfect gift for the science or chemistry lover in your life. Get yours today!

Safety

We get asked about the radioactivity and overall safety of the periodic table from time to time. These are legitimate concerns and we wanted to address those concerns here. Although several elements in the periodic table are dangerous or toxic, the acrylic and glass ampules make the collection safe to handle and store. The radiation from the uranium and thorium samples is extremely low. Autunite (uranium ore sample) has a radioactivity level of 0.01 mRem for a 2mm piece held in your hand for an hour. The average American is exposed to 0.034 mrem/hr from background radiation (300 mrem/year). In other words, a person will get three times the radiation from natural background radiation which includes the sun, food, radon, and the environment, than they will from holding the periodic table all day. https://www.nrc.gov/about-nrc/radiation/around-us/doses-daily-lives.html
