[Product Description]

• Smaller-size version foamed-polyethylene holders for electrode plates

[Overall Advantages to Users]

• Foamed-polyethylene holders for electrode metal plates possible to hold up to four (4) kinds of metals at one time, which leads to easier comparison of difference in e.g. generated charge between electrodes.
• User-friendly because preparation can be done by inserting metal plates into the slits of the products and put them on any container such as a beaker for those experiments to investigate difference between electrolyte and non-electrolyte and difference in ionization tendency between different type metals, as well as, to understand (the principle of) battery.
