Spotting Plates and Affiliation Plates
Spotting plates are a common tool used for microchemistry experiments. Each plate has many cavities or depressions that allow only a small amount of liquid to be added.
A spot plate is typically made of porcelain, a ceramic material strong enough to resist high temperatures and chemical corrosion.
Porcelain is a type of ceramic that consists of clay that has been fired to maturity. It is tough and nonporous, meaning it absorbs little or no water.
Its kiln-fired body and glaze resist stains, scratches, and dents. Its toughness and resistance to heat make it useful for dinnerware and other items used frequently in the home.
A porcelain spot plate, a reaction plate, or a culture plate is a laboratory tool for observing color change reactions and other chemical reactions. It has many depressions or wells (each about 20 mm in diameter) for performing responses on a small number of chemicals at a time.
Spot plates are durable, acid- and alkali-resistant, easy to clean, and autoclavable. They are often used in microchemistry experiments. They are available in various shapes and materials, including porcelain, polystyrene, and plastic. They can be purchased in packs of 12 or 24. They are not recommended for use with strong solvents.
A reputable home improvement or garden store should be your source for plastic or resin-based planters and planter-related trinkets of all shapes and sizes. The best ones are drool-proof and can be left alone for hours without a hitch. Some even come with matching lids a la the big green garden shed. To get the most bang for your buck, find a reputable supplier that will provide the necessary information to make your buying decision a breeze.
A spotting or cavitating plate is a chemistry lab tool to spot and measure the molecular structures of liquids and chemicals. These thick abrasion-resistant glass plates are durable and reusable, making them ideal for laboratory experiments requiring precise measurements.
These spotting plates come in a variety of shapes and sizes. The EMD Millipore concentrating zone plate is the most impressive, which includes a high-tech adsorption layer for selectively separating a sample from its surroundings. It also boasts a multi-layered, abrasion-resistant coating with an asymmetrical microstructure.
The best part is that it is available for a surprisingly reasonable price. We also offer a range of other lab-tested, second-hand equipment from the usual suspects.

Affiliation plates are special license plates designed to show support for or affiliation with various local and national organizations, charities, and causes. Typically, these plates cost an extra fee and represent something presumably special to the driver.
Some states have a distinctive color scheme for these specialty plates, often contrasting with the standard issue. These colors include red for municipal government plates, green for state police and other government vehicles, and brown with white lettering for other state-owned cars.
Many states also offer a variety of specialty plates for motorists with specific status or accomplishments (e.g., firefighter, EMT, amateur radio operator). Some also offer specialty plates for veterans who have received POW or Purple Heart medals.
