Ensuring Accurate Sample Dilution

Now available exclusively in the UK from Don Whitley Scientific, the Dilumat® S gravimetric diluter from AES Chemunex simplifies sample preparation for food and drink microbiology testing laboratories. Dilumat S automates the time-consuming dilution of solid and liquid

samples and ensures rapid and accurate 1/10 dilutions every time. This latest addition to the Dilumat range has a rotating arm that automatically lowers to the stomacher bag or vessel when ready to dispense. After dispensing, the arm rotates away from the sample preparation area to facilitate sample addition.

With a total capacity of 2.5kg and larger bore tubing, Dilumat S can accommodate increased sample volumes without any loss of accuracy. The improved pump is more reliable, easier to clean, and makes it much easier to load the tubing. Full open access to the sample bag avoids contact between the device and sample to reduce the risk of contamination. With an intuitive icon-driven display for simple operation, the device can be fully integrated with laboratory LIMS software or operate as a stand-alone unit.

A spokesperson at Microsearch Laboratories, commented: “Used every day, our Dilumat has become a major part of our sample preparation process. One of the major benefits is being sure that the dilution is done correctly prior to reaching post-analysis QC and realising that there is a problem. Often that’s just too late and ultimately wastes money, staff time and other valuable resources.”
