With Micronic's 1.40ml internal thread push cap tubes

The complete range of Micronic's internally threaded tubes

The Micronic 1.40ml internal thread push 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 push 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 and Comorack.
