The Screw Cap tube (internal thread)
features a single turn thread for easy
opening and closing of the tube
The Push Cap tube (internal thread)
has a special design that eliminates
caps to pop off during thawing
(-80ºC) or pushed in during piercing
The Screw Cap tube (external
thread) has a triple start thread for
optimal sealing quality
Black or white code surface (bottom
and/or side) cannot be separated
from the transparent tube due to
the patented 2K injection molding
technique
Permanent laser-etched code on the
tube bottom which is chemically,
scratch and mechanically resistant
(reference: Test Report TR022501)
Unique manufacturing process
All Micronic sample storage tubes are manufactured to industry leading strict tolerances. Due to the unique 2K injection molding
technique, the highly transparent tube and the code surface are molded to one component leading to the following advantages:
- Code surface cannot be separated from the transparent tube enabling absolute traceability
- Solid and uniform walls allow maximum working volume
- No contamination during the production process
- Multiple freeze-thaw cycles.
Extensive freeze-thaw tests are conducted with Micronic sample storage tubes and results show no leakages for both Micronic
Push Cap tubes and Micronic Screw Cap tubes closed with TPE caps. Additionally, research also shows that no Micronic TPE caps
pop off during the freeze-thaw process (reference: Test Report TR021901).
- Grinding of samples by high speed bead beating for DNA/RNA extraction.
When homogenizing samples, beads are often used to break open cell walls and membranes to release the desired DNA and
RNA. The solid walls of Micronic tubes have been tested and are able to withstand the process of bead beating easily (reference:
SAMPLE STORAGE TUBES
Micronic’s high quality and strong sample storage tubes are able to withstand:
Test Report TR021801 and TR022701).
