Improve your sample storage workflow

With Micronic's 1.40ml internal thread screw cap tubes!

The complete range of Micronic's internally threaded tubes

The Micronic 1.40ml internal thread screw cap tubes are available with a flat exterior bottom that provides an affordable way to improve sample storage, sample handling and logistical processes.

These tubes have a code surface that cannot be separated from the tube due to Micronic’s unique 2K injection molding technique. As a result, tube codes can never wear or fall off. The 1.40ml screw cap tubes can be purchased in a refill carrier, in bulk, in Micronic’s 96-well format ULT rack, or Micronic’s 96-well format Roborack.
