Caleva offers you a range of extruders and spheronizers.

If you plan to work with batch sizes from between 50 g and 1500 g then this Caleva kit will give you the flexibility you need.  The Multi-Bowl Spheronization Kit is designed for your laboratory bench-top and includes the following 2 pieces:

The Caleva bench-top screen Extruder 20 with a reduced or full height screen(s) and a Caleva Multi Bowl Spheronizer base with a 250mm, 120 mm, 85mm or 60mm diameter bowl.  You can obtain a single bowl with or all four bowl sizes (or buy additional bowls in the future as you need them.

Caleva Model 20 Vertical Screen Type Bench Top Laboratory Extruder
Designed for experimental formulation applications.  Material to be extruded is manually loaded into a top mounted feed tray.  A centrally driven, vertically orientated, rotating roller assembly located on the inside of the extrusion screen pushes the material to be extruded through the holes in the screen thereby producing an extrudate.  The extrudate that forms on the outside of the extruder screen falls by gravity and is collected in a manually removable collection tray.

The Caleva Multi-Bowl Bench Top Spheronizer
With a 250mm, 120 mm, 85mm or 60mm diameter bowl.  Designed for experimental formulation development.  With its optional interchangeable bowls, this spheronizer gives you the ability to work with a wide range of batch sizes, either now or in the future (50 g to 1.5 kg) with a single apparatus.

There is no other laboratory system designed for this range of batch sizes

It is your powerful combination for product development with flexibility that can be enhanced with additional options if you wish to work with smaller or larger batches and wish to automatically collect operational data during your work.  Ask us how the automatic collection of operational data with the Caleva Datastor can enhance your development work.
