¿What is a laboratory spatula?

In laboratories, the spatulas and micro spatulas are small stainless steel utensils, used to scrape, transfer or apply powders and pastes as products chemicals or treatments.

Many brands of spatulas are also resistant to acids, bases, heat and solvents, making them ideal for use with a wide range of compounds.

Types of Laboratory Spatulas

There are several types of laboratory spatulas, each with its own unique design and purpose. Here are some common types of spatulas:

  • Micro Spatula: This type of spatula is ideal for precise measurements and transferring small quantities of substances.
  • Double-ended Spatula: As the name suggests, this spatula has two different ends, typically one flat and one spoon-shaped. It is perfect for scooping and transferring substances.
  • Spoon Spatula: This type of spatula has a spoon-shaped end, making it convenient for scooping and mixing substances.
  • Tapered Spatula: A tapered spatula is designed with a pointed tip, which is useful for scraping, spreading, and lifting materials.

Uses of Laboratory Spatulas

Laboratory spatulas have a wide range of applications across various scientific disciplines. Some common uses include:

  1. Sample Handling: Spatulas are used to handle solid and semi-solid samples, allowing scientists to transfer, mix, and weigh them accurately.
  2. Chemical Reactions: In chemistry labs, spatulas are used to mix and combine chemicals during reactions, ensuring uniformity and effectiveness.
  3. Powder Dispensing: When working with fine powders, spatulas are used to dispense precise quantities into containers or reaction vessels.
  4. Culture Manipulation: In microbiology labs, spatulas are used to streak or spread bacterial cultures on solid culture media.
  5. Gel Manipulation: Spatulas are essential tools for handling gels in molecular biology research, such as DNA gels or protein gels.

Versatility of laboratory spatulas

Many brands of spatulas are also resistant to acids, bases, heat and solvents, making them ideal for use with a wide range of make.

A common type would be stainless steel spatulas, which are they are widely used because they are durable and affordable.

They are resistant to spoilage due to contact with boiling water, acids, bases and most solvents. Some of them come with a handle of polyvinyl chloride plastic or riveted hardwood for better handling.

Polystyrene spatulas are made for researchers because they are disposable, which prevents any potential contamination from occurring often with reusable spatulas. They are also ideal for handling lyophilized products or to perform lyophilizations.

Spatula function in laboratory

  1. Sample Handling: Spatulas are commonly used to handle and transfer small quantities of solid substances. This is crucial for precise measurements and to avoid contamination when working with chemicals or powders.
  2. Mixing and Stirring: Spatulas are valuable tools for mixing and stirring substances. They help ensure a thorough and uniform distribution of materials, particularly when blending powders or granules.
  3. Sampling: Spatulas are employed to collect samples of substances for further analysis or to transfer them into different containers. They allow scientists to obtain representative samples from larger quantities of material.
  4. Dispensing: In situations where precise measurements are required, spatulas can be used to dispense small quantities of a substance, ensuring accuracy.
  5. Cleaning: Spatulas are useful for cleaning glassware and other equipment in the lab. They can help remove residues and solid materials without causing damage to glass or other surfaces.
  6. Preventing Contamination: Spatulas are essential for avoiding cross-contamination between different substances, particularly in experiments where maintaining the purity of samples is crucial.
  7. Handling Hazardous Materials: Spatulas provide a safe means of handling potentially hazardous materials, reducing the risk of exposure to harmful substances.

Laboratory micro spatula

A micro spatula, which it is a portable device, it is used in chemical laboratories to flip, trimming and spreading substances during chemical analyses.

A typical primary sheet measures 30 x 60 millimeters. The other end has a blade with the same dimensions, but with a slight upward inclination. The average length of a spatula tool is 7 inches.

Maintenance of stainless steel spatulas

Stainless steels they need to be cleaned for aesthetic considerations and to preserve the corrosion resistance.

Any contamination of the surface by dirt or other material prevents the natural process of passivation and traps the corrosive agents, thus reducing the protection against the rust.

Some form of cleaning routine is necessary to preserve the appearance and integrity of the surface and really thrive with frequent cleaning. Unlike other materials, it is impossible to "wear out" stainless steel with excessive cleaning.

Like any surface that is used can get dirty, which can consist of accumulated dust and a variety of contaminants that come from many sources in the laboratory.
These pollutants vary greatly in their effect on the appearance and effects of corrosion.

While some they can be easily removed, others may require specific cleaners for effective removal and it may be necessary to identify the contaminant or experiment with various cleaners.

Warm water with or without a mild detergent is often enough. The next step is non-scratching soft abrasive powders and general-purpose cleaning solutions. These can be used with warm water, bristle brushes, sponges or clean cloths.

Types of cleaners and methods

Clean water and wipes is the simpler method and stainless steel surfaces thrive with a frequent cleaning. A soft cloth and clean warm water should always be the first choice for soft stains and dirt and loose floors.

A final rinse with clean water and a dry rag will complete the process and eliminate the possibility of stains from water.

Ultrasonic water baths Clifton can be useful for a cleaning process, using the activity ultrasonic, in a water-based detergent solution that removes residues and the dirt.

A final rinse with clean water and a dry rag will complete the process and eliminate the possibility of stains from water.

Solvent cleaning with organic solvents can be used to remove fresh residues, oils, chemicals that have not had time to oxidize or break. The preferred solvent is one that does not contain chlorine, such as acetone, methyl alcohol and mineral spirits.

There are many organic compound or blended cleaners that are commercially available. Cleaning can be carried out by immersing the smaller items directly in the solvent, wiping them with solvent-impregnated cloths or using steam or spray methods.

Commercial cleaners

Many commercial cleaners phosphate compounds, synthetic detergents and alkalis are available for the cleaning of heavily soiled or stained stainless steel surfaces.

When used with a variety of cleaning methods, these cleaners can provide a effective cleaning in a safe way.

A neutral low chloride cleaner is preferred and should be rinsed thoroughly after cleaning. The fact that the label says "for stainless steel" does not guarantee that the product is suitable.
