The DisperCool 3000 is used for the preparation and sample conditioning of uncured as well as cured rubber samples prior to the cutting process - especially designed for Dispersion Testing.

The sample preparation process is very simple and convenient:
First the sample is pre-cut (if needed) and then easily placed in the quickopen sample holder and then inserted into the tabletop DisperCool unit. Inside the DisperCool chamber, silicon oil is pre-chilled to a low temperature from minus 20 to minus 40°C. The sample holder is placed into the chamber which can hold up to two sample holders. Once the safety lid of the chamber is closed, the cooling process and integrated timer are immediately started.

During the cooling process, the sample is cooled to glass transition temperature. This means that a totally solid sample is produced.

The cooling / preparation time – usually between 5 and 12 minutes depending on the sample type and shape – can easily be set by the operator and can be monitored during the process on a count-down timer display. Once the cooling time is over, the operator is notified by an acoustic signal allowing the operator to open the chamber lid and take out the sample holder along with the sample.

Now the sample at glass transition temperature can be cut and processed like a normal solid hard rubber sample without smearing, distortion or modification of the sample surface. The DisperCool 3000 provides perfect samples for conventional cutters or automatic cutters like the DisperCut 3000.

The whole DisperCool 3000 process is closed, sustainable and environmentally friendly as no consumables like liquid nitrogen or other cooling gases are required.
