Product documentation
A laboratory ultrapure water system is a point-of-use purification and dispensing plant for analytical and research work. The system removes ions, particles, organics and microorganisms that can interfere with instruments and methods. KONCHE laboratory systems deliver ultrapure water at 18.2 MΩ·cm resistivity at 25 °C. TOC ≤5 ppb is documented in selected configurations, with ultrapure capacity from 5 to 100 L/h and pure-water capacity from 10 to 200 L/h for routine duties. RO, EDI and ion-exchange stages are arranged to the verified feed water. General laboratory pure water, reagent preparation water and high-sensitivity analytical water are treated as different duties. The required grade is confirmed at the point of use, because storage and distribution can degrade polished water before dispensing. Configurations may integrate pretreatment, RO, ion exchange and terminal filtration in one system, with storage and dispensing arranged per laboratory.
KONCHE laboratory systems chain PP + activated-carbon + softening pretreatment, RO, EDI, 254/185 nm UV and ultrafiltration. Type I water reaches 18.2 MΩ·cm with TOC < 5 ppb; a second grade delivers ≥5 MΩ·cm general laboratory water. Capacities span 5–100 L/h, compliant with GB/T 33087-2016 and ASTM D1193 Type I, with a 7-inch touch screen, out-of-spec alarms, cartridge-life prediction and quiet < 50 dB operation. Typical projects: HPLC/ICP/IC analysis, life science (PCR, cell culture), pharmaceutical R&D, semiconductor wafer rinsing and clinical analyzers.

PRODUCT DOCUMENTATION
A laboratory ultrapure water system should be selected by the application, target water quality, feed-water condition, required capacity and points of use—not by the Type I label alone. KONCHE laboratory systems cover 5–100 L/h of ultrapure water and 10–200 L/h of pure water. Selected configurations can reach 18.2 MΩ·cm, while TOC ≤5 ppb and UV or UF modules remain application-specific. Before requesting a configuration, define the application, feed water, target quality, hourly and daily demand, points of use and peak-demand periods.
WHICH ULTRAPURE WATER SYSTEM SUITS MY LAB?
Start with the application and the contaminants that can affect the method or instrument. This guide to choosing a laboratory water purification system explains the five inputs in detail. The required water grade must come from the applicable method, instrument manual or laboratory standard; a Type I label alone does not establish suitability.
Start with the application and contamination risk
Analytical instruments, life-science workflows, general laboratory work and shared laboratories can have different limits for ions, organic compounds, particles and microorganisms. When the feed-water route is still being defined, compare distilled, deionized and RO water for laboratories before selecting the polishing stage.
Match hourly capacity to daily demand and peak use
KONCHE laboratory systems cover 5–100 L/h of ultrapure water and 10–200 L/h of pure water. Keep the two flows separate. Storage, simultaneous demand and peak-use periods must be defined before an hourly rating can be converted into a project configuration.
Separate laboratory point-of-use systems from industrial UPW
Laboratory systems are specified in litres per hour for point-of-use or shared-laboratory duties. Larger process duties should be evaluated as industrial ultrapure water systems, while semiconductor and related manufacturing duties may require a separate electronic-grade ultrapure water system.
| Selection input | What to define before selection | Boundary |
|---|---|---|
| Application | General laboratory work, analytical instruments, life-science workflows or a shared laboratory | The application category does not replace the method or instrument requirement. |
| Target water requirement | The parameters and sampling point specified by the method, instrument or applicable standard | Do not assume that Type I is required for every duty. |
| Feed-water condition | Tap, pretreated or purified feed, supported by a current water analysis | Feed water determines the pretreatment and consumable load. |
| Ultrapure-water demand | Select within the 5–100 L/h product range | Do not assign a flow from the application name alone. |
| Pure-water demand | Select within the 10–200 L/h product range | Keep pure-water and ultrapure-water demand separate. |
| Points and peak use | Number of points, simultaneous use and peak-demand periods | These inputs affect storage and distribution decisions. |
| Application modules | Polishing, UV or UF where the application requires them | Modules are configuration-specific, not universal standard equipment. |
If purified feed is not available, the project may also require single- or double-stage RO pretreatment. The final arrangement depends on the verified feed-water analysis and target water quality.
WHEN DOES A LABORATORY ULTRAPURE WATER SYSTEM NEED UV OR UF?
UV and UF are selected by application
UV and UF should be selected around the target contaminants, method and point-of-use requirement. KONCHE laboratory configurations may use polishing, UV or ultrafiltration systems where the application requires them. This does not mean that every model includes continuous UV recirculation, a fixed wavelength combination or a fixed removal result.
A dedicated TOC-UV system is a separate engineering decision
Application-specific UV or UF inside a laboratory system is not the same selection decision as a dedicated loop reactor for trace-organic control. Read how 185 nm UV is used for TOC reduction, then review the dedicated TOC UV degradation system when the project has a separate flow, feed-TOC and outlet-TOC duty.
WHAT AFFECTS THE PRICE OF AN ULTRAPURE WATER PURIFICATION SYSTEM?
A useful quotation defines the feed water, target quality, production capacity, storage and distribution duty, application modules and replacement scope. These inputs explain why two systems with the same nominal flow can require different treatment stages and service items.
| Cost factor | Why it changes the configuration | What to provide |
|---|---|---|
| Feed-water condition | Changes pretreatment and consumable load | A current feed-water analysis and the available feed type |
| Target water quality | Changes polishing and application modules | Required parameters, method and sampling point |
| Production capacity | Defines the ultrapure- and pure-water production ranges | Hourly and daily demand for each water grade |
| Storage and distribution | Depends on points of use, peak demand and shared supply | Point count, simultaneous use and peak periods |
| Application modules | UV or UF may be added where the application requires them | Contaminants and method-specific risks to control |
| Replacement and service scope | Defines the supplied maintenance and replacement items | Site service expectations and the requested spare-parts scope |
Review the relevant water treatment consumables as part of the replacement scope. KONCHE does not calculate a price or service interval from flow alone.

FAQ
Which ultrapure water system suits my lab?
Choose from the application, target water parameters, feed-water condition, required ultrapure- and pure-water capacity, points of use and contamination-control needs. The method or instrument requirement should define the target water quality.
What capacity should a laboratory ultrapure water system have?
Define hourly and daily demand for ultrapure and pure water separately, then add the number of points, simultaneous use and peak-demand periods. KONCHE laboratory systems cover 5–100 L/h of ultrapure water and 10–200 L/h of pure water.
When is UV or UF needed in a laboratory water system?
UV or UF is selected when the application requires additional control of organics, microorganisms or particles. The required module and duty depend on the method, feed water and point-of-use specification; they are not universal standard equipment.
What affects the price of an ultrapure water purification system?
Feed-water condition, target water quality, production capacity, storage and distribution, application modules, replacement items and service scope all affect the configuration and quotation.
What is the difference between pure and ultrapure water?
Pure water supports many routine laboratory duties. Ultrapure water is further polished for applications in which ionic, organic, particle or microbial contamination can affect the method or instrument. Use the applicable method or instrument requirement to set the final specification.
Can one laboratory system serve multiple points?
Multiple points must be evaluated from their water-quality requirement, simultaneous demand, peak periods and distribution arrangement. Provide those inputs so storage and distribution can be configured for the project.
