spatula
The spatula is a small flat scoop for applying, taking out, mixing or removing substances. The name is Middle High German as (the) spatula derived from the Latin word spatula ("spatula, flat match"), a diminutive of the sword form Spatha . Spatulas are particularly found in the chemical laboratory as laboratory equipment , in the pharmaceutical sector for stirring when preparing medicines , in medicine as a flat scoop for applying medicines and as a diagnostic device , and in the food sector as work or kitchen equipment , namely in the food industry and in the nutrition trade or in the household and when cooking (especially when baking ).
Usage today
Spatulas are mainly used as a laboratory device for scraping, grinding , picking up and transporting small amounts of chemicals in the laboratory. They consist of different materials ( iron , titanium , platinum , gemstone , nickel , ceramic , wood , horn, plastic or glass ) and can have different shapes (e.g. flat spatula, Drigalski spatula or spoon spatula).
As a rule, spatulas cannot be used for stirring in aggressive solutions : Metal spatulas - including those made of stainless steel - corrode e.g. B. in (concentrated) acids , lacquered spatulas are attacked by some solvents . Glass rods , Teflon rods or - stir bars are chemically more stable than spatula in most cases.
In the household, spatulas are used to apply and spread dough and coatings. An ice spatula is used for ice cream .
Small plastic spatulas are often used to open electronic devices ( cell phones , remote controls , computers ) if their plastic housings are held together by tabs with barbs .
Occasionally, spatula is confused with spatula .
