Innova Ultrapure Water Solutions: Exceeding Laboratory Standards

Exceeding Standards: Comprehensively meets and far exceeds the technical requirements of TCVN 4851 (ISO 3696), TCVN 8128 (ISO 11133), and CLSI.

Maximum Ion Purity: Type I water achieves 18.2 MOhm.cm, exceeding TCVN Grade 1 requirement (> 10 MOhm.cm).

Far Exceeds Grade 2: Type II water (10-15 MOhm.cm) specifications far exceed TCVN Grade 2 requirement (>= 1 MOhm.cm).

Addresses Standard "Gaps": Addresses risks unaddressed by the TCVN 4851 (ISO 3696) standard, which does not specify limits for Total Organic Carbon (TOC) and Bacteria.

250x Lower TOC: Achieves TOC < 2 ppb, which is 250 times lower than the CLSI requirement (< 500 ppb).

5000x Lower Bacteria: Achieves < 0.01 CFU/mL, which is 5,000 times lower than TCVN microbiology practice (< 50 CFU/mL).

Innova Ultrapure Water Solutions:
Exceeding Laboratory Standards

Water quality is a foundational element that directly impacts the reliability of analytical results. In Vietnam, laboratories (labs) operate based on National Standards (TCVN), which are primarily based on ISO standards:

TCVN 4851:1989 (ISO 3696:1987): Specifies 3 grades of water for chemical analysis.
TCVN 8128:2015 (ISO 11133:2014): Standard for the preparation of microbiological culture media.
CLSI (Clinical Laboratory Reagent Water): Standard for the medical and testing sector.

Meanwhile, Innova systems are designed according to the US ASTM D1193 standard—one of the most stringent standard sets. The technical comparison table below clearly demonstrates the superior capabilities of Innova water when compared to TCVN and CLSI requirements.

Detailed Specification Comparison Table

From the comparison table, two critical technical observations can be made:

Regarding Ion Purity (Resistivity):

Innova's Type I (18.2 MOhm.cm) and Type II (10-15 MOhm.cm) water both have specifications that exceed the requirements of TCVN 4851 Grade 1 (> 10 MOhm.cm) and far exceed the requirements of Grade 2 (> 1 MOhm.cm).

Addressing the "Gaps" in TCVN 4851 (TOC & Microbe):

The TCVN 4851 (ISO 3696) standard does not specify limits for Total Organic Carbon (TOC) and Bacteria. These are two factors that can cause significant interference in modern applications (like organic analysis, chromatography) and biological processes. Innova systems, through compliance with ASTM D1193 and integrated technology (e.g., 185nm UV lamp, final filter), tightly control these parameters:

TOC: Achieves < 2 ppb (Type I), which is 250 times lower than the CLSI requirement (< 500 ppb).
Bacteria: Achieves < 0.01 CFU/mL, which is 1,000 times lower than CLSI (< 10 CFU/mL) and 5,000 times lower than TCVN microbiology practice (< 50 CFU/mL).

Innova systems (compliant with ASTM D1193) not only comprehensively meet but also far exceed the technical requirements of TCVN 4851 (ISO 3696), TCVN 8128 (ISO 11133), and CLSI. By adhering to the ASTM standard, Innova ensures output water has higher ion purity and addresses the "gaps" of TCVN 4851: tightly controlling impurities (TOC, bacteria, endotoxins) that this standard leaves unspecified. This provides a water source of the highest reliability, protecting the integrity of analytical results even in the most sensitive applications.
