As the practice of clinical analysis gained popularity in the 1960s, so did the number of test tubes in hospital laboratories. Over time, these tubes and the bulky wooden racks which held them would take up more and more valuable space, and present a storage problem.

Responding to this rather mundane but pressing challenge led Víctor Grífols i Lucas to design and patent a light-weight, Z-shaped aluminum holder that could be transported and stored easily, in 1962.

 

A tube for every purpose

Víctor Grífols designed and manufactured racks with capacity for tubes of three different diameters, depending on their use: 12mm for immunohematology reactions, 14.5mm for chemical reactions and general use, and finally 17mm for standard test tubes.

In addition, he designed them grouping the holes into two clearly differentiated and separated groups of five rows and five columns each, which made the location and differentiation of the tubes much faster.

The production of anodized aluminum racks was a sales success, becoming the most popular model in Spanish laboratories. It also enjoyed good sales in Switzerland and Germany.

Even today Grifols manufactures and markets a large variety of aluminum racks. Those with 48 holes are one of the most used, since they adapt more easily to microplate techniques and the capacity of centrifuges.
