Test Tubes with a Twist

Welcome to the first post of our new blog series Supplies with a Twist! 

The goal of this series to introduce new, exciting, and maybe never thought of, uses for some of the more common laboratory supplies. These new applications will span from the lab to home and school use. Maybe even a few of them will consider uses in the future, both near and far. Who knows. 

Today we are tackling one of the most commonly used item: A Test Tube, specifically plastic test tubes with caps. We will first go through the more traditional use cases in a laboratory and expand into classroom/education uses, decorative applications and more. The content for this blog came from brainstorming with other scientists, ChatGPT, and my own crazy imagination. I hope you enjoy.

 

Traditional Laboratory Uses

  • Specimen collection: Collecting and transporting specimens such as, blood, water, dirt, or any CSI related specimen to name a few.
  • Centrifugation: Test tubes are designed to withstand centrifugal forces, allowing researchers to separate and isolate different components of a sample through centrifugation.
  • Chemical reactions: In my lab days, I loved to watch the reaction proceed and plastic capped test tubes were my go to choice for this.
  • Cell culture: Grow and maintain cell lines. The caps provide a sterile environment, preventing contamination and ensuring the integrity of the cell culture.
  • Cryogenic storage: Some plastic test tubes can withstand extreme temperatures, making them suitable for cryogenic storage or liquid nitrogen.
  • Assay and analysis: Used in assays and analytical techniques, including enzyme-linked immunosorbent assays (ELISA), polymerase chain reaction (PCR), spectrophotometry, and fluorescence measurements. The tubes provide a convenient vessel for sample preparation and analysis.
  • Transport and shipping: The secure caps help prevent leakage or contamination during transit.

Most of you are familiar with the traditional uses of plastic test tubes. Let's get to some of the more creative uses.

Classroom/educational uses

  • Science experiments: Test tubes are not limited to laboratories. They can be used for simple science experiments at home or in educational settings. For example, you can create a lava lamp effect by combining water, oil, food coloring, and an effervescent tablet inside a test tube. Conduct simple experiments like mixing different liquids, observing color changes, creating homemade lava lamps, or growing small plants from seeds. The capped test tubes provide a safe and contained environment for kid-friendly experiments.
  • Artistic experiments: Use test tubes as artistic tools for creating unique patterns or designs. Fill the tubes with different colored paints or dyes, seal them tightly, and then manipulate or rotate them to create visually interesting patterns on paper or canvas.
  • Sound experiments: Explore the science of sound by using test tubes as resonating chambers. Fill the tubes with varying levels of liquid or different materials, seal them with caps, and tap on the tubes to produce different tones. You can experiment with different tube lengths, liquid levels, or even add small objects inside the tubes to alter the sound.
  • Micro-garden experiments: Create mini ecosystems within test tubes by adding soil, seeds, and small plants. Seal the tubes with caps to create a self-contained environment for observing plant growth and development. These micro-garden experiments can be an engaging way to study plant biology and explore different growing conditions.
  • Chromatography experiments: Test tubes can be used for chromatography experiments, such as paper chromatography or thin-layer chromatography. Fill the tubes with appropriate solvents and stationary phases, seal them with caps, and use them as containers for separating and analyzing different compounds or pigments.
  • Decorative Art projects: Test tubes can be incorporated into art projects and crafts. Students can use them as unique containers for creating mini terrariums, storing colored sand for decorative projects, or as vases for small flowers or plant cuttings.
  • Temperature gradient experiments: Create a temperature gradient within a test tube by adding liquids with different boiling points or by partially immersing the tube in a temperature-controlled bath. Observe the movement of fluids within the tube as the temperature changes and explore the concept of thermal convection.
  • Magnetic experiments: Use test tubes to study the behavior of magnetic materials or to create small-scale magnetic experiments. Fill the tubes with magnetic materials like iron filings or magnetic fluids, seal them with caps, and investigate how they interact with magnets or magnetic fields.
  • Math manipulatives: Test tubes can be used as math manipulatives for various mathematical concepts. They can be filled with different objects like buttons, beads, or counters, and students can use them for counting, sorting, or representing numerical operations.
  • Sensory activities: Test tubes can be utilized for sensory activities in early childhood education. Teachers can fill the tubes with various materials like colored water, oil, or gel, and seal them with caps. Students can observe and explore the different textures, colors, and movements of the materials.

As you can begin to see, there is almost no end to the uses of these simple yet amazing laboratory items. Here are Science Outfitters we have multiple types of plastic test tubes available.

Crazy/Future Ideas 

Now, if you want to go a little bit into the future, ok maybe a lot. I asked ChatGPT what it thought the possible uses of test tubes might be in the future. And I was not disappointed in the answer.

 

In a science fiction scenario, imagine a futuristic laboratory where advanced technology allows for the containment and manipulation of time. Plastic capped test tubes could be used as vessels to store and transport samples of compressed time. These test tubes would have specialized caps that create a temporal barrier, trapping and isolating a specific moment or sequence of time within the tube.

Scientists in this fictional world could conduct experiments on temporal manipulation, studying the effects of compressed time on various materials, organisms, or even exploring the potential for time travel. The test tubes would act as miniature time capsules, holding unique temporal properties that could be harnessed for scientific exploration and discovery.
