Benchtop Or Wall Mount Base System, /50Hz Overview
The Benchtop Or Wall Mount Base System, /50Hz (model WA311B) is a Type I water purification system from Yamato Scientific, supplied by LabSupplies.com as an authorized dealer. This compact unit produces ultrapure reagent water on demand at 18.2 MΩ·cm resistivity for laboratories that need consistent deionized water.
Purification runs through conditioning and polishing cartridges finished by a 0.2 micron final filter. Quick-change, no-tools cartridges carry premium ResinTech ion-exchange media, keeping maintenance fast and cost of ownership low. Typical output reaches 2.5 LPM (0.67 GPM) from feed water under 20 µS/cm.
Operating on 220V / 50 Hz, the system installs on a benchtop or mounts on a wall to suit tight lab footprints. Cabinet dimensions measure 21.6 in × 14.7 in × 14.4 in, and the unit weighs 34.1 lbs. Built in the USA, it includes real-time quality monitoring with leak detection.
Key Features
- Type I ultrapure output: 18.2 MΩ·cm resistivity, TOC below 15 ppb, and bacteria under 1 cfu/ml for demanding reagent-grade applications.
- Quick-change cartridges: no-tools design loaded with premium ResinTech ion-exchange media for fast media swaps.
- 0.2 micron final filter: polishes dispensed water to remove fine particulates and microbial contamination.
- Real-time monitoring: continuous water-quality readout paired with integrated leak detection.
- Flexible installation: benchtop or wall-mount configuration to fit constrained lab spaces.
- Typical 2.5 LPM flow: 0.67 GPM delivery from feed water under 20 µS/cm.
How to Choose the Right Water Purification System
Selecting a purification system starts with the water quality your protocols require, then balances flow, installation space, and site power. Match these axes to your lab before specifying a unit.
- Water quality grade: Type I ultrapure (18.2 MΩ·cm) suits HPLC, molecular biology, and reagent prep; lower grades fit general rinsing. WA311B targets Type I.
- Flow rate: typical 2.5 LPM determines how quickly you can fill large vessels or feed downstream instruments.
- Feed water requirement: the unit expects feed under 20 µS/cm, so confirm your source or pretreatment meets that threshold.
- Installation footprint: benchtop or wall-mount flexibility matters when bench space is limited.
- Voltage and frequency: this model runs on 220V / 50 Hz; verify it matches your facility power.
- Monitoring and maintenance: real-time quality readout, leak detection, and no-tools cartridge changes reduce downtime.
