EPPi® Kryo-Röhrchen 
mit Außengewinde

EPPi is the name given to National Lab's revolutionary externally threaded cryotubes. The term EPPi® is a protected word mark of National Lab in Mölln. The difference to conventional cryo-tubes with external thread
with external threads is the super slim shape,
which makes it possible for the first time to store 100 cryogenic tubes with external threads in a standard 133x133 mm box. The 133x133 mm box format is of American origin and is used in almost all laboratories around the world. The unpopular disadvantage of these boxes is the internal division with only 9x9 spaces for cryogenic tubes with external threads. Only 81 instead of 100 cryo-tubes fit into each box. This wastes expensive storage space in -86°C freezers and liquid stick fabric containers.
The EPPi cryogenic tubes and EPPi boxes put an end to this. Although trivial, the fact that 100 cryogenic tubes with external threads fit into the standard 133x133 mm box is a real innovation. EPPi cryo tubes and EPPi boxes are made in Germany
