The Rotoshake 12 from Gerhardt UK is designed to evaluate potential hazards when handling or disposing of waste.
The main problem with waste disposal is the release of soluble components upon contact with water.
The analysis of representative waste samples is necessary and is defined by European Standards for waste acceptance criteria.
In order to replicate conditions for the analysis of leachate water, this particular standard procedure requires an overhead shaker with a rotation speed of 5-10 turns per minute.
The elution should be done at room temperature in a wide-neck flask with a designated volume of 2 litres.
Approximately 100g of sample is weighed accurately to 1g from a representative sample of approximately 2kg, with a particle size of less than 10mm.
Continuous 24-hour shaking is required using a powerful motor and sturdy construction.
At the end of the elution process the non-diluted residue is separated and the solution analysed further.
The pH value and conductivity provide information about the extracted substances.
The Rotoshake 12 can meet all these requirements.
The shaker can even be loaded unevenly due to the design of the drive of the cylinder and powerful, maintenance-free motors.
All moving parts are protected behind a closed safety hood.
In addition, up to nine shaking programmes can be defined with continuous monitoring of each individual programme.
