Benchtop - With Ultrafiltration Module, /50Hz Overview
The Benchtop - With Ultrafiltration Module, /50Hz (Yamato WB311UFB) is a Type I ultrapure water purification system that delivers 18.2 MΩ·cm resistivity water at a typical 2.5 LPM (0.67 GPM) flow rate. Yamato Scientific engineers this compact unit for labs that need pyrogen-free, nuclease-free water on demand. LabSupplies.com supplies it as an authorized dealer.
An integrated ultrafiltration module pairs with conditioning and polishing cartridges plus a 0.2 micron final filter to remove pyrogens and produce nuclease-free output. Quick-change, no-tools cartridges use premium ResinTech ion-exchange media. Real-time quality monitoring with leak detection tracks output and protects the bench.
Operating on 220V / 50 Hz, the WB311UFB mounts on a benchtop or wall to fit tight footprints. Unit dimensions measure 21.6" × 14.7" × 14.4" (54.8 × 37 × 36.5 cm), with a shipping weight of 35.1 lbs. Made in USA. TOC runs below 15 ppb and bacteria below 1 cfu/ml.

How to Choose the Right Water Purification System
Matching a purification system to your protocols starts with the water grade your applications demand and the supporting utilities your bench can provide. Review the axes below before specifying.
- Water type and quality: Type I ultrapure (18.2 MΩ·cm) suits molecular biology, HPLC, and cell culture; confirm your assays require this grade.
- Pyrogen and nuclease control: an ultrafiltration module and 0.2 micron filter matter when downstream work needs pyrogen-free, nuclease-free water.
- Flow rate: a typical 2.5 LPM (0.67 GPM) determines how quickly you can fill vessels for routine throughput.
- Feed water requirement: verify your source stays below 20 µS/cm to maintain rated performance.
- Voltage and power: the 220V / 50 Hz supply must match your facility's available circuit.
- Footprint and mounting: benchtop or wall-mount options fit labs where bench space is limited.
