Final answer:
Spatulas are used to remove product from jars effectively and without waste, maintaining cleanliness and safety while maximizing the use of the product.
Step-by-step explanation:
Spatulas are used to remove product from jars to ensure effective and efficient retrieval of the contents. They are designed to fit into the contours of jars and scoop out materials without spillage or waste. Spatulas help in getting every last drop of a product from a jar, thereby maximizing usage and reducing waste.
This is particularly important in both cooking and laboratory settings where precision and frugality are crucial. For instance, in a laboratory, it is essential not to contaminate the product, hence a clean spatula is used. Additionally, using a spatula can also be a safe way to handle substances that should not be touched directly with hands.
