Frequently Asked Questions

Will sealed glass test tubes burst when boiled?

Yes, sealed glass test tubes can burst when boiled. This is because as the water inside the test tube heats up, it expands and creates pressure. If the test tube is sealed, there is no way for the pressure to escape, and it will eventually build up to a point where the test tube bursts.

How to sterilize plastic test tubes?

You can sterilize plastic test tubes in many ways. Autoclaving is the most effective method for sterilizing plastic test tubes. It uses steam under pressure to kill all microorganisms, including spores. To autoclave plastic test tubes, follow these steps:

1. Place the test tubes in an autoclave bag or wrap.
2. Load the autoclave with the test tubes.
3. Close the autoclave and set the temperature to 121°C (250°F) and the pressure to 15 psi (103 kPa).
4. Start the autoclave and let it run for 30 minutes.
5. Once the cycle is complete, let the autoclave cool down before removing the test tubes.

Which test tubes are controls in the experiment?

Both Glass test tubes and plastic test tubes are controls in the experiments.

What are tiny plastic test tubes called?

A tiny plastic test tube refer to as a microcentrifuge tube or microfuge tube. These small, conical-shaped tubes are typically made of polypropylene or polyethylene and have a volume range of 0.5 to 2.0 milliliters (mL).

How do I clean test tubes effectively?

Rinse the test tubes with a suitable cleaning solution (e.g., soap and water or a laboratory detergent), use a brush to scrub the inside, rinse thoroughly with water, and air-dry upside down.
