ملعقة بسط
A spatula is "a small implement with a broad, flat, flexible blade used to mix, spread and lift material"[1] including foods, drugs, plaster and paints. It derives from the Latin word for a flat piece of wood or splint (a diminutive form of the Latin spatha, meaning broadsword), and hence can also refer to a tongue depressor. The words spade (digging tool) and spathe are similarly derived. The word spatula is known to have been used in English since 1525.[2]

Laboratory use
In laboratories, spatulas and microspatulas are small stainless steel utensils, used for scraping, transferring, or applying powders and paste like chemicals or treatments.[5] Many spatula brands are also resistant to acids, bases, heat, and solvents, which make them ideal for use with a wide range of compound. [6] A common type would be stainless steel spatulas, which are widely used because they are sturdy and affordable. They are resistant to deterioration from contact with boiling water, acids, bases, and most solvents. Some of them come with Polyvinyl chloride plastic handle or riveted hardwood for better handling. Polystyrene spatulas are made for researchers because they are disposable, preventing any potential contaminations which occurs often with reusable spatulas. They are also ideal for handling lyophilized products or performing lyophilization.
