Gravimetric Diluters and Sample Weighing Systems

Introduction to Gravimetric Diluters and Sample Weighing Systems

Gravimetric diluters and sample weighing systems are specialized instruments used to weigh samples and automatically dispense the appropriate volume of diluent in microbiological or chemical sample preparation procedures. The equipment helps optimize sample preparation steps, minimize manual handling, and ensure accurate repeatability between analyses.

When purchasing a gravimetric diluter and sample weighing system, users need to consider the maximum capacity, such as 3kg or 5kg, to suit the actual sample weight, along with a single-pump or double-pump configuration depending on the number of diluents to be dispensed automatically. At Hoa Viet, this category includes the DiluFlow, DiluFlow Pro, and DiluFlow Elite gravimetric diluters from manufacturer Interscience (France).

When should you choose a single-pump diluter and when a double-pump diluter?

The single-pump version is suitable for laboratories using only a single fixed diluent. Meanwhile, the double-pump version allows simultaneous connection to two different media, providing flexible switching without the need to disconnect and reassemble tubing.

What are the available weighing capacities of Interscience diluters?

Interscience diluters are currently available with a capacity of 3kg on the standard DiluFlow model and 5kg on the DiluFlow Pro or DiluFlow Elite models. Users can select the appropriate model based on the sample weight including the sample bag.

Which brands of gravimetric diluters and sample weighing systems does Hoa Viet provide?

What should be kept in mind regarding the maintenance and operation of a sample diluter?

Users should clean the tubing system and dispensing nozzle after each work shift to prevent culture media residue buildup. In addition, placing the device on a flat, anti-vibration surface and periodically inspecting the peristaltic pump tubing will help maintain dispensing accuracy.
