Poly(methyl methacrylate) (PMMA), also known as acrylic or acrylic glass, is a transparent thermoplastic often used in sheet form as a lightweight or shatter-resistant alternative to glass. Dental pmma discs is made of a millable resin with properties that closely mirror those of a nature tooth, making it a fawless solution for laboratories to reduce processing time by eliminating labor-intensive metal investing and casting procedures in the workflow process.

A PTFE stirring rod is a piece of laboratory equipment used to mix chemicals. It's thicker and slightly longer than a drinking straw, with rounded ends. A stirring rod is used for mixing liquids, or solids and liquids. Stir rods are used as part of proper laboratory technique when decanting supernatants because the contact helps to negate the adhesion between the side of the glassware and the supernatant that is responsible for the liquid running down the side.

Molybdenum is a chemical element with the symbol Mo and atomic number 42 which is located in period 5 and group 6. The name is from Neo-Latin molybdaenum, which is based on Ancient Greek Μόλυβδος molybdos, meaning lead, since its ores were confused with lead ores. Molybdenum minerals have been known throughout history, but the element was discovered (in the sense of differentiating it as a new entity from the mineral salts of other metals) in 1778 by Carl Wilhelm Scheele. The metal was first isolated in 1781 by Peter Jacob Hjelm.

Polyvinyl chloride resin generally has a high level of chemical resistance. This may not be seen, however, when the material is exposed to organic chemicals. PVC is also strong and resistant to water and abrasion. This material is very popular in the construction industry. It can be used to produce many items needed in the building process. Those items are often lightweight, long lasting and maintenance-free.

A fidget toy is typically a small object used for pleasant but purposeless activity with the hands (manual fidgeting or stimming). Some users believe these toys help them tolerate anxiety, frustration, agitation, boredom, or excitement.

Puffer toy is a self-regulation tool used with children who have a difficult time sitting still or focusing. The toy helps promote focus and concentration, and keep the body (fingers) busy so they can still sit and focus! Puffer toys are also great for strengthening hand muscles and building fine motor and finger dexterity.
