IONPURE LabXT CEDI Module RO-EDI Water System for Laboratory Ultrapure Water System

　　Ionpure LabXT is a laboratory-scale CEDI module for ro-edi water systems and laboratory ultrapure water systems,producing 3 to 15 L/h of high-purity water.Designed as a direct drop-in replacement for EMD Millipore Elix modules,it uses low-extractable polysulfone construction,universal voltage power input,and 6 mm push-in tube fittings.Suited for analytical instruments,clinical analyzers,and benchtop ultrapure water polishing.

　　What Is a Laboratory CEDI Module?

　　A laboratory CEDI module is a compact electrochemical deionization device that polishes reverse osmosis permeate into high-resistivity water for lab use without chemical regeneration.It combines ion-exchange membranes,mixed-bed resin,and a DC electric field to continuously remove dissolved ions and weakly ionized species such as silica and carbon dioxide.

　　Laboratory CEDI modules are categorized by flow rate,ranging from point-of-use(under 2 L/h)to benchtop-scale units delivering up to 20 L/h.The Ionpure LabXT series sits in the 3–15 L/h segment,optimized for direct integration into existing ultrapure water systems or as a stand-alone polishing stage for single instruments and small networks.

　　Technical Highlights

　　Direct Elix module replacement eliminates system requalification.The LabXT shares mechanical connections and electrical interface with legacy Millipore Elix CEDI modules.Users can swap a depleted Elix module with a LabXT without modifying plumbing,power wiring,or control logic,reducing both downtime and service labor.

　　Low-extractable polysulfone protects sensitive analyses.The natural polysulfone body minimizes organic and ionic leaching.This is essential for HPLC,ion chromatography,and trace metal analysis where ppb-level contaminants from module construction can contribute to baseline noise.

　　Universal power supply simplifies global procurement.The dedicated LabXT power supply accepts 100–227 VAC at 50 or 60 Hz and provides selectable current output,allowing the same module to be installed in laboratories operating on various mains voltages without a transformer.

　　Tool-free 6 mm push-in tube connections accelerate installation.The module and adapters use push-in fittings compatible with standard polyethylene and polypropylene tubing.No special tools,clamps,or skilled piping labor are required.

　　Four-channel flow design delivers leak-free continuous operation.Internal flow channels and elastomer sealing are arranged to prevent intercompartment mixing,ensuring consistent product resistivity over the module lifetime.

　　Applications

　　Analytical laboratory water systems:Polishes RO permeate to 5–15 MΩ·cm for feeding glassware washers,autoclaves,and general chemistry.The module replaces up to 300 L of bottled purified water per week,cutting cost per liter by more than 80%.

　　High-performance liquid chromatography and ion chromatography:Supplies ultrapure water for mobile phase preparation and sample dilution.Silica removal>99.9%prevents siliceous deposits on columns and detector flow cells.

　　Clinical analyzer and diagnostic instrument feed:Provides continuous high-purity rinse water for hematology and immunoassay platforms,eliminating bottle change-outs and reducing technician intervention to an annual module swap.

　　Elix system refurbishment and lifetime extension:Allows laboratory facility managers to swap end-of-life Elix modules with a pin-and plumbing-compatible LabXT module,recovering full ultrapure water production without replacing the entire water system.

　　Selection Guidance

　　Suitable applications:

　　Laboratories running EMD Millipore Elix systems where the CEDI module has reached the end of its service life and a plug-and-play replacement is required to avoid system downtime

　　New benchtop ultrapure water systems with a demand of 3–15 L/h and feed water already meeting≤60µS/cm conductivity and≤2.5 ppm hardness as CaCO₃

　　Applications requiring continuous ultrapure water but lacking floor space for a conventional mixed-bed cylinder and chemical storage

　　Not recommended for:

　　Feed water with hardness consistently above 2.5 ppm or silica above 1.5 ppm.In such cases a softener and additional RO stage should precede the module,or a higher-tolerance process CEDI module such as the Ionpure VNX30-CDIT should be evaluated.

　　Point-of-use polishing of water already meeting>15 MΩ·cm.The LabXT is a primary deionization module and does not provide 18.2 MΩ·cm ultrapure water suitable for critical semiconductor or mass spectrometry applications without downstream polishing.

　　Flows below 2 L/h where intermittent operation may cause stagnation.For such low demand,consider a small ion-exchange cartridge or a point-of-use dispenser with a built-in recirculation loop.

　　FAQ

　　1.What is the difference between the LabXT3,LabXT5,LabXT10,and LabXT15 models?

　　The four models differ only in nominal product flow:3,5,10,and 15 liters per hour.Dimensions,connections,water quality performance,and pretreatment requirements are identical across the series.We recommend selecting the model that most closely matches your continuous water demand to maintain stable resistivity.

　　2.How much does the LabXT module cost,and what is the price range per model?

　　Ionpure LabXT modules typically range from 2,800to5,200 USD depending on the flow rating and regional distribution.Prices fluctuate due to exchange rates,tariffs,and factory adjustments.For an accurate quotation including the power supply and optional fittings,contact Beijing Zhongping Technology directly.

　　3.Is the LabXT a direct replacement for the Millipore Elix module?

　　Yes.The LabXT is mechanically and electrically compatible with Elix CEDI modules.It uses the same mounting points,push-in plumbing connections,and power cable interface.No system control changes or recalibration are required when swapping an Elix module for a LabXT.

　　4.Is the power supply included,and what voltage does the LabXT require?

　　The power supply is ordered separately to let you reuse an existing working unit.It accepts a universal input of 100–227 VAC,50/60 Hz,with selectable output of 100–200 mA.A replacement LabXT power supply carries UL,CSA,and CE certifications.

　　5.What warranty and return policy apply to the LabXT module?

　　A 2-year warranty covers all LabXT modules against manufacturing defects,with extended service agreements available upon request.Unused modules in original packaging may be returned within 30 days of delivery with prior authorization.Beijing Zhongping Technology processes return authorizations within one business day.

　　6.Can I install the LabXT myself or do I need an engineer?

　　The LabXT is designed for user installation.No specialist tools are required;the module mounts onto existing brackets and connects via 6 mm push-in tube fittings and a polarized power plug.Beijing Zhongping Technology provides an illustrated installation guide and remote commissioning support at no additional charge for first-time purchasers.

　　7.How often does the LabXT module need replacement or maintenance?

　　Service life is typically 3–5 years under normal laboratory conditions with good RO feed water.No routine maintenance is required between replacements.We recommend periodic monitoring of product resistivity and feed water hardness;a gradual decline in resistivity below 5 MΩ·cm indicates that replacement is due.

　　8.What is the cost per liter of ultrapure water using LabXT compared to bottled water?Typical operating cost for LabXT-produced ultrapure water is less than0.02perliter,includingmoduleamortizationandelectricity,comparedto0.25-$1.00 per literfor bottled HPLC-grade water.This cost advantage increases with higher daily consumption.

　　9.What feed water quality or pretreatment does the LabXT need?

　　Feed water must be RO permeate with conductivity below 60µS/cm,hardness≤2.5 ppm as CaCO₃,silica≤1.5 ppm,and free chlorine below 0.02 ppm.For municipal tap water sources,we recommend a reverse osmosis system with activated carbon and softening pre-filters.Beijing Zhongping Technology can specify a suitable RO pretreatment skid based on your site water analysis.

　　10.Do you offer volume discounts or purchasing agreements for multiple LabXT modules?

　　Yes.Tiered pricing begins at three units,and multi-year service contracts covering scheduled replacements across a campus or network of laboratories provide additional savings.Contact Beijing Zhongping Technology for a multi-unit proposal or blanket purchase agreement.
