About THINKY ARV-501 Planetary Centrifugal Vacuum Mixer

The THINKY ARV-501 is a mid-sized mixer able to homogeneously mix all engineering compounds including silicones, adhesives, conductive pastes, pharmaceuticals and many other materials. It operates using THINKY’s industrial non-contact “planetary” mixing technology, and is able to mix, disperse and degas up to 700g of material within minutes, eliminating any micro-bubbles.

The ARV-501 has an optional stand, the ARV-PU501, which includes a built in vacuum pump. Mixing can be achieved under vacuum by using the ARV-PU501 or another external vacuum pump in order to achieve a completely bubble-free result. Mixing and degassing can be done without vacuum by using the two standard modes, “mixing” and “defoaming”. Non-vacuum mixing is useful for solvented  or highly volatile materials, or for when a less critical mix is needed. THINKY’s cup holder vacuum design minimises the overall vacuum volume, and so keeps the process time required to achieve vacuum and to restore atmospheric pressure to a minimum.

The ARV-501 comes with 550ml HDPE thick wall jars, including inner lid & cap, as standard. There is a standard version with a hole in the cap to facilitate vacuum mixing.  Materials can be mixed in other sealed or lid-less containers such as jars, beakers, syringes or cartridges; we provide adaptors so they fit in the ARV-501.

The THINKY ARV-501’s multi-step mixing feature allows 20 different programs to be set containing mixing and degassing conditions (time and speed per mode) in a single batch cycle. These programs are set up and stored using the inbuilt touch screen control panel. RS232 connectivity allows recording of each process for traceability, start/stop, program editing, etc.


This Technical Bulletin, Vacuum Mixing & Degassing, discusses the differences between non-vacuum and vacuum Thinky mixers and processes, and when they are needed.
