Smart Dilutor W
Gravimetric diluter
About Smart Dilutor W
Smart Dilutor W is IUL’s gravimetric dilutor and dispenser for fast, accurate, and repeatable sample preparation and liquid handling.
Using high-precision weighing and peristaltic pumping, it controls dispensing by actual weight, reducing variability and delivering up to 100 mL in 6 seconds with >99% accuracy (models without filter).
Available with one or two pumps, Smart Dilutor W can work with bottles, ready-to-use media bags, or combined configurations, with optional inline filtration for greater flexibility.
Designed to adapt to different laboratory workflows, it combines reliable dispensing with flexible setup options.

Frequently Asked Questions
The Smart Dilutor W performs real-time gravimetric verification for every dispensing process, helping eliminate errors commonly associated with manual pipetting while improving efficiency in high-throughput laboratories. Users can also perform gravimetric calibration directly from the instrument menu using a standard weight, without requiring external service support.
Yes. The Smart Dilutor W can dispense into a wide range of sample containers, including bottles, flasks, beakers, and other vessels. Optional accessories, such as a flask adapter and multilevel arm, provide flexibility for different container sizes and configurations.
The Smart Dilutor W with Filter enables in-line sterile filtration directly from bottle-based diluent sources, creating a closed and controlled workflow. This reduces the risk of contamination, eliminates the need to autoclave diluent bottles before use, and streamlines routine dilution procedures.
Yes. The Smart Dilutor W accurately dispenses sterile diluents, broths, and other liquids, making it ideal for preparing culture media and supporting microbiology laboratory workflows.
Yes. The Smart Dilutor W supports data export to a PC for electronic record keeping, traceability, and compliance documentation. It can also connect to a printer for immediate printing of results and reports.
