A laboratory spatula is a small hand tool used in laboratories to handle and transfer small quantities of solid or powdered chemicals. It resembles a miniature version of a kitchen spatula or a flat scoop and is commonly made of stainless steel, plastic, or other chemically resistant materials.
Common Features:
Shape and Size:
- Flat Blade: Ideal for scooping, scraping, or spreading substances.
- Spoon-End or Double-Ended: Some spatulas have one flat blade and one spoon-like end for versatility.
Material:
- Stainless Steel: Durable, resistant to corrosion, and suitable for high-temperature applications.
- Plastic or Polymers: Lightweight and suitable for corrosive substances but less durable.
Size Options:
- Available in various lengths and widths to accommodate different tasks.
Uses:
- Transferring Chemicals: Used to move small quantities of powders, granules, or pastes from one container to another.
- Mixing: Helps in blending materials, especially in small-scale experiments.
- Scraping: Removes residues from containers or glassware.
- Measuring: Assists in precise handling of substances when weighing.
Types:
Micro-Spatulas: Smaller versions for precision tasks.
Double-Ended Spatulas: Offer two different tools on either end for multi-purpose use.
Disposable Spatulas: Made of plastic for single-use to prevent cross-contamination.
