In order to keep a laboratory well organized and free from any hitches, it is important that one chooses the right test tube rack for their research needs. Test tube racks come in different styles, materials and sizes, therefore choosing the most suitable one depends on the specific requirements.

Factors to consider when selecting a test tube rack are as follows:

Rack Material:

  1. Plastic: Plastic test tube racks are lightweight, cheap and do not corrode. They can be used in almost all kinds of laboratory activities and cleaning them is easy.
  2. Metal: Metal racks made of stainless steel or aluminum are sturdy, can withstand harsh chemicals and autoclaving. They are good for hot environments or corrosive ones.
  3. Wood: These are not common but they serve some purposes. However, wooden versions are not long-lasting as plastic or metal versions and require more care to prevent damage by moisture or chemicals.

Tube Size Compatibility:

Ensure the chosen test tube rack caters for those that you use during your experiments regarding size and type. Some examples of such include those meant for microcentrifuge tubes and standard test tubes among others.


Consider how many tubes you want to hold at once before you decide on the particular type of test tube rack to buy. Ranging from racks containing just a few tubes up to several dozens, this will suit your daily laboratory needs.


Choose between horizontal and vertical racks based on your workspace’s configuration as well as your preferred method of accessing tubes. While horizontal racks allow easy access to the content inside them, vertical types save space.


Spills can be avoided only if stability is maintained all the time. Racks that have strong bases and non-slipping grip feet should be considered for use because they give a secure feeling when placed in position.


When sterilizing your equipment, make sure that it can be autoclaved if necessary. Usually, plastic racks can be autoclaved at a certain temperature only while metal racks are autoclavable.

Chemical Resistance:

Determine whether the rack material can resist the chemicals and reagents used in your experiment. The connection between some chemicals and specific materials can cause rusting and damage of the equipment.


Consider the durability of the rack especially if it will be used for longer periods or under harsh conditions. Metal racks have more life than plastic racks.

Ease of Cleaning:

It is important to take into account how easy it is to clean the rack as this is a significant aspect of keeping a laboratory sterile. Check whether it is possible to clean the rack without any complications after using it.


When selecting you should also have in mind your budget. There are different priced ones but getting one that matches with what you want is however paramount.

Finally, while choosing a test tube rack for yourself, consider these following factors depending on the kind of research you are undertaking and also based on where you will carry out laboratory activities. By putting all this into consideration, you will be able to select the most appropriate test tube rack for the kind of research work that you do; hence enhancing an organized and efficient laboratory set up.
