As a researcher, working with cell cultures is a vital aspect of your work. Dealing with cell cultures requires extensive knowledge and careful handling to protect the integrity of your experiment and generate accurate results. One essential tool you need is the T-75 cell culture flask.

In this blog post, we will discuss the proper use of a T-75 cell culture flask. We will cover everything from preparation to cell culturing and care.

What is a T-75 Cell Culture Flask?

A T-75 cell culture flask is a laboratory instrument used to house and cultivate cell cultures. It is a popular choice because it provides ample space for cell growth by providing a surface area of 75 cm². Additionally, it can hold up to 250 ml of medium, which is crucial for maintaining proper cells' nutrient levels and minimizing the risk of contamination.

Preparing for Cell Culturing.

It's essential to prepare the T-75 cell culture flask correctly before introducing cells. Here are a few steps to follow:

Step 1: Sterilize the flask.

Before using the T-75 cell culture flask, you must sterilize it. Sterilization helps to eliminate any bacteria growth. To sterilize the flask, soak it in 70% ethanol for five minutes and allow it to dry. You can also autoclave the flask for 30 minutes on a dry cycle.

Step 2: Prepare the cell culture medium.

You need to prepare the cell culture medium. The culture medium serves as the cells' food and provides the necessary nutrients and chemicals needed for growth. Follow the manufacturer's instructions and ensure that it comprises all the necessary ingredients.

Step 3: Thawing the cells.

If you are using frozen cells, you need to thaw them properly before culturing. Thaw the cells rapidly on a 37-degree Celsius water bath for around two minutes, then transfer them to a sterile culture dish, and add the appropriate medium.

Cell Culturing.

Once the flask is ready to use, it's time to introduce your cells into the medium.

Step 1: Add the medium to the flask.

Add the appropriate volume of medium to the flask. Experts recommend filling the flask halfway initially, then adding more medium later if necessary. A shallow culture medium can lead to evaporation, affecting cell growth.

Step 2: Add the cells.

When introducing cells into the flask, it's crucial to work in a sterile environment to prevent contamination. The easiest way to introduce cells is to use a sterile pipette. You can quickly examine the flask under a microscope to confirm the placement of cells.

Step 3: Incubating the Flask.

After introducing cells, put the flask in an incubator to allow the cells to grow. Depending on the cell type, the optimal temperature can usually be set at 37 degrees Celsius. Cells also require specific oxygen and carbon dioxide levels. The standard conditions in an incubator are around 5% carbon dioxide.

Care and Maintenance.

After culturing, it's crucial to take care of the flask and maintain it correctly to prolong its lifespan and improve your results.

Step 1: Monitor the cell growth.

It's vital to observe the cells' growth inside the flask regularly. Depending on the cell type and the experiment you're conducting, you may need to change the medium every two to three days.

Step 2: Prevent contamination.

Preventing contamination is the most crucial aspect of T-75 cell culture flask care. You must maintain a sterile environment when handling the flask and changing the medium. Keep the work area clean and sterile to eliminate the chances of contamination.

Step 3: Store properly.

After use, clean the T-75 cell culture flask with a warm, soapy solution and rinse it thoroughly with distilled water. Sterilize it and leave it to dry before storing it safely. Remember to check the expiry date of the flask before use.

Final Thoughts.

The T-75 cell culture flask is a crucial tool in cell culture studies. Proper preparation, cell culturing, and care can improve the accuracy of your research results. Follow the outlined steps above to ensure your cell assays are successful. No matter what experiments you are conducting, remember to experiment with caution and follow all laboratory safety requirements.
