RoSS.PADL | Homogenizing Solution

Cool & Gentle Homogeneity

RoSS.PADL is a platform to standardize cooling of your single-use bag while it is gently kneaded to ensure a homogenous mixture of your substance. 

With the RoSS.PADL platform, multiple cooling and kneading mechanisms can be placed side by side to scale-up with one control system.

What makes RoSS.PADL the optimal solutions?

Automate your process

Where normally an operator would massage the bag, this process can be automated to increase process efficience and reduce the risk of inconsisten product quality. The removal of human invervention means a scalable process for one or more bioprocess containers in parallel and the reduced risk of human error in bag handling.

Bag agnostic

No matter the manufacturer of the bag, the RoSS.PADL Homogenizer does not differentiate and is scalable to the customer's needs.

Fluid homogeneity through kneading & cooling

Using the adjustable massaging mechanism and the cooling plate, it is possible to ensure homogeneity during draining of the single-use bag. With the cooling plate, it is possible to keep the mixture between -20°C to +35°C/-4°F to 95°F ensuring optimum temperatures during draining. The cooling plate can also be turned off.

Controllable with other RoSS devices

Seamless integration into end-to-end solutions from Single Use Support. Simple combination with protective RoSS Shells for single-use bags, RoSS.pFTU Freeze-Thaw Platforms and RoSS.FILL Fill-Drain Units.

RoSS.PADL Homogenizer

Cool your fluid & generate homogeneity.

RoSS.PADL is a scalable platform for cooling your single-use bag whilst also using one paddle that gently kneads the bag. It ensure that there is a homogenous mixture of the solution. The optional cooling mechanism ensures that the correct temperature is maintained. In addition, the biocontainer can be completely emptied due to the slope.

In some instances, human intervention is used to massage the bags during draining. With RoSS.PADL this is no longer necessary. With the RoSS.PADL multiple cooling and massaging mechanisms becomes automated, reproducible and therefore standardized. Bags can be placed side by side with one control system to increase process efficiency.

RoSS.PADL provides a further solution within the Single Use Support end-to-end process and is controllable with the RoSS.FILL Fill & Drain Platform.
