In environments where water purity is non-negotiable, Type 1 deionized (DI) water is essential. Laboratories, hospitals, and biopharma operations in Chicago require Type 1 DI water that meets the highest resistivity and purity standards for critical applications such as reagent preparation, molecular diagnostics, and cell culture. Meredith's Culligan delivers advanced Type 1 DI water systems specifically engineered to meet these demanding requirements.
What Is Type 1 Deionized Water?
- Defined by ASTM and CLSI as ultrapure water with resistivity of 18 Mฮฉ-cm at 25ยฐC.
- Must contain extremely low levels of organic compounds, endotoxins, particulates, and bacteria.
- Required for applications like HPLC, ICP-MS, DNA sequencing, and sensitive analytical procedures.
What Meredith's Culligan Offers for Type 1 DI Water Needs
Multi-Stage Ultrapure Water Systems
- Our systems begin with a base Reverse Osmosis (RO) unit that removes up to 99% of total dissolved solids.
- Includes critical pre-treatment technologies:
- Carbon Filtration โ Removes chlorine/chloramines to protect membranes.
- Sediment Filters โ Trap particulates and prevent fouling of downstream components.
- Water Softeners โ Extend membrane life and improve overall system efficiency.
Deionization & Final Polishing Stages
- Mixed-Bed DI Resin Cartridges or Tanks โ Deliver ultrapure water through ion exchange.
- UV Oxidation โ Reduces total organic carbon (TOC) and neutralizes microbial contamination.
- 0.2 Micron Final Filters โ Eliminate particulates and bacteria just before point-of-use.
- System designs support point-of-use or centralized distribution, depending on your facilityโs layout.
Portable Exchange DI Tank Service
- For facilities that prefer external regeneration and no on-site chemical handling.
- High-capacity tanks available to maintain uninterrupted supply.
- Professionally maintained and replaced by our highly trained technicians based in the Chicago area.
