Spatulas used in labs or not the same type that you find in an everyday kitchen. These spatulas are normally all metal with a smaller putty knife like end and the other end is more tapered for accessing smaller areas. You may seem spatulas that have a wooden handle and a wider metal piece as well. There are also microspatulas used in laboratory settings as well. These are very similar to the normal spatula but smaller as the name suggests. The equipment can also be used for stirring and mixing compounds in small containers.
