Twist Tube
The test tube has remained the same shape for centuries. Now, researchers
at Norwind-Cortez, an Ypsilanti, Mich.-based biotechnology firm, have
patented a version with a shape they believe improves upon the familiar
phallic form.
The new tube looks like its traditional counterpart with a bend at the open
end. This and a flat side allow the vessel to rest horizontally without a
rack. According to Norwind-Cortez president Milt Jackson, the bent tube
reduces the risk of contamination, allows for more contact with air for
cell culture experiments, and heats and cools more quickly. Licensing
negotiations are under way.
