Simple ideas often are the best ones, for example, the aquarium heater as a rod. The heating rod is simply hung in the water and heats it. It's true that principle is still the same as decades ago, but a lot has changed in the meantime. Today the JGER aquarium heater is an ultra-modern thermal device using the best available technology. Now - with in its new jacket of laboratory glass - it offers another an extra quality dimension.
Laboratory safety glass was made for research purposes. Therefore, it is free from pollutants, which could seep into the water. It is resistant to chemical and biological substances. It does not have any fissures and hair cracks, which condensation water can penetrate. And it is shatter-proof ie. resistant to cold water shock, which can occur during maintenance or sudden water level changes.
