In laboratories, different utensils are required to support the various instruments that are required in experiments and other processes. A rack is one of those instruments, it is used to support and store test tubes. They can be made of wood, plastic or metal.

What is it?

It is a tool that is part of the laboratory material (especially in molecular biology, chemistry and genetics laboratories) and is used to hold and store test tubes or Eppendorf tubes.

Its main function is to facilitate the transport and handling of test tubes. Thanks to its use, greater comfort and safety is guaranteed when working in the laboratory.

Most racks (with the exception of stainless steel and multi-position racks) are numbered to facilitate sample location and identification.

The anodized aluminum racks are very durable and resistant to chemical and corrosive agents. They are available in three sizes, they are Z-shaped and their wide, flat base gives them stability.

What is it for?

  • The functions of the racks include:
  • They are used to hold and store this material.
  • They collaborate in the organization of the test tubes and provide support to the test tubes in which it works.
  • They prevent spills, falls and fractures in the test tubes.
  • They facilitate the organization of the samples.
  • They allow you to observe the behavior of several samples at the same time.

Rack types according to their function

Among the different types of racks there are:

Classic rack: These are commonly found in laboratories. They are made of plastic, wood or stainless steel.

Interlocking cubic rack : These are several racks organized in the shape of a cube. The racks located on one side are detached for use.

Stackable rack: They are made of polypropylene and can be placed in the autoclave.

Drying rack for test tubes: Used for drying and storing chromatography plates and for drying test tubes.

Inclined rack: Used to keep the tube holes on the required side. They are used for certain crops where a uniform angle is required in all test tubes.

One-Piece Rack: They are designed to hold a single test tube.

Vial racks: These are those designed for containers or small ampoules.

Types of racks according to their material

According to the material in which they are made, we have:

  • Racks with lid.
  • Foam rubber racks.
  • Incubation racks.
  • Graders of isofreeze.
  • Single-use racks.

Born and raised in Brussels in an English family, I have always lived in a multicultural environment. After several work experiences in marketing and communication, I came to Smart Water Magazine, which I describe as the most exciting challenge of my career.
I am a person with great restlessness and curiosity to learn, discover what I do not know, as well as reinvent myself daily, someone who is curious about life and wants to know. I enjoy sharing knowledge.
This is my personal project but I also collaborate in other blogs, it is the case, the most important web on water currently exists in the US, if you are interested you can read my articles here.
