Laboratory Spatula: Usage & Maintenance

Laboratory Spatula: Usage & Maintenance

Laboratory spatulas are quintessential tools in scientific research, offering precision and versatility in handling various substances. These instruments come in diverse shapes, sizes, and materials, each designed for specific purposes in the lab. Whether you’re a seasoned researcher or a newcomer to the scientific realm, understanding how to use a laboratory spatula effectively is key to accurate experimentation and analysis.

Types of Laboratory Spatulas

Laboratory spatulas are primarily categorised into two main types:

  1. Micro Spatulas: These are small, slender spatulas with a thin, pointed blade on one end and a spoon or flat blade on the other. Micro Spatulas are ideal for transferring small amounts of solid chemicals or powders with precision.
  1. Double-Ended Spatulas: These spatulas feature different shapes or sizes on each end, providing versatility for various laboratory tasks. One end might have a flat, rounded, or spoon-shaped blade, while the opposite end could be a sharp point or a different type of blade.

Materials and Their Uses

Laboratory spatulas come in different materials, each serving distinct purposes:

Stainless Steel:

  • Pros: Durable, resistant to corrosion, easy to clean.
  • Suitability: Versatile for both solid and liquid handling tasks.
  • Recommended for: Beginners due to its balance of durability and ease of maintenance.


  • Pros: Similar qualities to stainless steel.
  • Considerations: Slightly less common and might be more expensive.
  • Suitability: Comparable to stainless steel for various laboratory tasks.


  • Pros: Lightweight, less likely to scratch surfaces, low cost.
  • Considerations: Less durable, not suitable for high-temperature tasks.
  • Recommended for: Delicate materials or situations where cross-contamination avoidance is crucial.

Choosing the appropriate material for laboratory spatulas should consider the specific tasks, substances handled, and durability required for the experiments or procedures conducted in the lab.

Proper Techniques for Using a Laboratory Spatula

Knowing how to use a laboratory spatula means mastering the proper techniques. While getting more experience will be your best teacher, we broke down the process to get you started if you’re new to this apparatus:

techniques in using a laboratory spatula
  1. Selection: Choose the appropriate spatula based on the substance being handled. For example, a micro spatula is suitable for small amounts of powders, while a larger double-ended spatula may be needed for bigger quantities.
  2. Cleaning: Before and after each use, ensure the spatula is clean and free of any residues. Stainless steel spatulas can typically be autoclaved or washed with solvents. Disposable plastic spatulas should be discarded after a single use to prevent contamination.
  3. Handling Solids: When transferring solids, gently scoop or scrape the material using the appropriate end of the spatula. Avoid using excessive force to prevent spills or inaccuracies.
  4. Mixing and Stirring: For mixing substances or scraping residue from containers, utilise the flat end of the spatula. Stirring should be done gently to prevent splashing or losing material.
  5. Avoid Cross-Contamination: If handling different substances, clean the spatula thoroughly or use separate spatulas to prevent contamination between samples.
  6. Safety Precautions: Wear appropriate personal protective equipment (PPE), such as gloves and safety goggles, especially when handling potentially hazardous substances.

Types of Cleaners To Use When Cleaning Spatulas

Knowing how to use a laboratory spatula and keeping your lab spatulas clean is important for doing accurate experiments. Identifying the type of cleaners you should use can help you clean them properly without messing up your tests. Here are the main types of cleaners you can use:

  1. Liquid Cleaners:
  • Alcohol (like rubbing alcohol): Good for cleaning and removing things like oil and dirt. It dries quickly and doesn't leave much behind.
  • Acetone: Strong and helpful for cleaning tough stuff on spatulas, but it might not work well with all spatula materials.
  1. Soap-Based Cleaners:
  • Mild Soap: Using soapy water can help clean most spatulas. It's gentle and removes greasy or watery things.
  • Special Cleaners for Bio Stuff: These are good for cleaning spatulas used with living things or proteins.
  1. Cleaning Tools:
  • Soft Brushes or Pads: Sometimes, spatulas have hard stuff stuck on them. Using soft brushes or pads can help clean without scratching the spatula.
  1. Special Cleaners:
  • Cleaners for Metal Stains: If your spatula has stains from metal, special cleaners called chelating agents can help remove them.
  • Gentle Cleaners: Some cleaners are nice for cleaning delicate spatulas without harming them.
  1. Sterilising Ways:
  • Heat or UV Light: Heat can clean some spatulas if they can handle high temperatures. UV light is also good for killing germs on spatulas.

When you pick a cleaner, it's important to know what your spatula is made of and what kind of stuff it deals with. Always follow the lab rules and what the manufacturer says to ensure your spatula stays clean.

Can You Substitute a Baking Spatula for Lab Use?

In a pinch, a baking spatula could be used in a laboratory setting for non-critical, non-reactive tasks. However, it's crucial to understand the limitations. 

Baking spatulas are typically designed for food handling, so using them in a lab might risk contamination or inaccurate measurements due to residue. They lack the precision, sterilization, and material standards necessary for scientific experimentation. So only consider using a baking spatula for lab use, when you really need it.

Proper Storage of Laboratory Spatulas

Maintaining laboratory spatulas properly is essential for their longevity and functionality. Clean and completely dry the spatula after each use to prevent corrosion or contamination. Store them in designated containers or racks, ensuring they're not in contact with reactive substances or other metals that might cause reactions. Segregating spatulas based on their usage (i.e., organic vs. inorganic materials) helps prevent cross-contamination.


Mastering laboratory spatulas involves understanding their types, selecting the right one for the task, employing proper handling techniques, and ensuring maintenance and cleanliness. By following these guidelines, scientists and researchers can effectively utilise laboratory spatulas for precise and accurate experimentation while maintaining a safe laboratory environment.
