A laboratory spatula is used for mixing, spreading and holding chemicals in a laboratory. In most cases, spatulas are made of stainless steel to prevent corrosion and provide clean mixing. However, certain spatula implements are made using rubber and polymers such as nylon.
Depending on their intended functions, spatulas can have either soft or steel blades. Soft spatulas have flexible and refined edges, but they don't provide as much mixing resistance as steel spatulas. Micro lab spatulas are excellent for handling extremely small samples. Stainless steel and nickel spatulas are particularly versatile, especially when coated with polypropylene, and they feature excellent heat and chemical resistance. Lab spatulas can be sterile, nonsterile or single use.
Spatulas are also used for transporting and distributing dry chemical compounds during chemical analyses. They're used when weighing chemicals on a balance because they allow users to collect extremely small quantities. A microspatula, which is a hand-held device, is used in chemical laboratories for flipping, clipping and spreading substances during chemical analyses. A typical primary blade measures 30 x 60 millimeters. The other end has a blade with the same dimensions, but it has a slight upward bend. The average length of a spatula tool is 7 inches.
