Gravimetric Diluter

A rapid, accurate gravimetric diluter for combining solid samples with the correct amount of diluent, automating the laborious task of making and standardising initial sample dilution.

Place your sample in a blender bag and the DILUWEL weighs the sample and adds the correct amount of diluent to achieve your preset dilution. 225 ml of diluent can be added in 12 seconds (or 9 seconds in turbo mode!) with a >99% accuracy. The patented vertical weighing system offers greater stability and accuracy due to a fully integrated spirit level and height adjustable feet.

The DILUWEL is light enough to be moved around the lab. It is also very easy to keep clean with a durable, stainless steel bag holding. An additional 3 pumps can be added if required.

The ‘Finger-stop’ nozzle helps to prevent cross contamination during installation.
