Liquid & Solid Sampling Devices
Lab blender
Gravimetric dilutor
Two sampling accessories help optimize liquid and solid sample preparation prior to smell, VOC or taste analysis, especially for food & beverage applications:
- The gravimetric dilutor for automated weighing of the sample & diluent based on the desired dilution rate - Gravimetric dilutor brochure
- The lab blender for automated crushing and homogenization of samples, to transform solids into liquids and provide samples free of particles using filter bags - Lab blender brochure
Advantages
- Insures that the analyzed portion of the sample is representative of the whole product
- Guarantees homogeneous & repeatable samples.
