Starting from the need to have a Cyclonic sampler in our portfolio, we decided to use what guaranteed us reliability, durability and that we had tested for a long time. For this reason we decided to use part of our easySPT100, the “base”, because it is compact, efficient and also battery powered. Once we decided on the “starting point” we designed the Cyclonic reverse flow head trying to avoid all known problems. In particular, we designed a drum to hold 8 Eppendorf, used two motors (one for rotation and the other for drum lifting) and avoided sensors that suffer from dust and dirt. We have also redesigned the pump impeller to increase the suction capacity up to 25 l/m. Last but not least, an easySPT100 can be transformed into an easySPT300 by simply changing the cover allowing two different sampling methods with just one base! The result is a very compact “Cyclonic”, battery powered and easy to maintain.
The mechanics of the instrument is a group of three main parts:
- The Cyclone Head.
- The motor group.
- The drum for the Eppendorf.
It’s a mixture of Plastica and aluminum with a dedicated electronics for the control of movements of the drum. It’s managed by the same electronics contained in the easySPT100 sampler. We have also provided a little backup battery to allow the extraction of the drum even if main supply are are disconnected or too low.
This part is designed to allow the creation of vortexing air necessary to capture particles up to 1um. The particular conformation and dimension of the internal hole is studied for the best performance of the head with an air suction of around 16 l/m. The inside of the head will be treated to avoid sedimentation of the dirt even if it will be necessary to clean it regularly. For this reason the head is easily removable.
7 Days drum for Eppendorf
This is a drum to support up to 7 Eppendorf of 1.5ml and our idea is that the drum may be carry to the laboratory by using a custody (like easySPT100/200). The drum is also necessary to allow the rotation of the eppendorf under the Cyclone Head. The rotation is necessary for a 7 days sampling.
