A professional medical testing and quality control (QC) laboratory focuses on medical sample detection and data verification.
The laboratory requires a continuous and stable supply of high-purity purified water.
The standard water resistivity must reach ≥18.2 MΩ·cm to meet laboratory-grade requirements.
High-purity water is widely used for daily chemical testing and precision instrument maintenance.
It is also an essential raw material for biological buffer preparation and reagent dilution.
Any impurity or ion contamination will directly affect experimental data and detection accuracy.
Therefore, the laboratory demands ultra-clean, non-leaching and stable water storage containers.
Existing Drawbacks of Traditional Containers
Before the upgrade, the laboratory adopted two mainstream storage containers.
One was traditional large glass water tanks for purified water placement.
Glass tanks were extremely heavy and fragile during daily handling and movement.
More importantly, unstable glass materials easily leach trace metal impurities.
These impurities reduce water resistivity and interfere with precision testing results.
The second option was disposable plastic water containers.
Although disposable plastics are clean, they generated massive plastic waste.
Frequent container replacement caused high long-term procurement costs.
Both traditional solutions failed to balance purity, safety and economic benefits.
Customized Liquid Container Solution
To solve impurity leaching and high-cost problems, the lab selected our reusable foldable square plastic tank.
This 20L container is made of premium medical-grade LDPE raw materials.
It strictly passes ISO 13485 medical device certification for biological laboratory scenarios.
Designed as a square bag-in-box liquid storage drum, it has a composite structure.
It combines an integrated rigid base and a flexible sterile inner bag.
The rigid bottom ensures stable placement, while the soft inner layer avoids ion precipitation.
Structural & Functional Advantages
This flexible water tank supports repeated cleaning and high-temperature autoclaving.
The container can be reused up to 10 sterilization cycles without material aging.
Compared with single-use plastics, it reduces plastic waste by 90%.
The inner bag adopts ultra-clean sterile material with zero impurity leaching.
It effectively maintains high water purity for a long storage period.
The purified water resistivity remains stably above ≥18.0 MΩ·cm for more than 7 days.
The cubical shape optimizes stacking efficiency and saves laboratory storage space.
12-Month On-site Application Results
The laboratory completed a 12-month continuous practical application test.
The new flexible containers brought remarkable optimization effects.
Impurity-induced water deterioration batches decreased significantly.
The laboratory successfully reduced purified water waste by 50%.
The abandonment of glass tanks completely eliminated glass breakage safety risks.
Thanks to its reusable design, the annual container cost was cut by 65%.
Stable Data & Long-term Promotion
Daily water quality monitoring records verified stable water conductivity.
No foreign particles or chemical impurities appeared during storage.
The stored purified water caused zero negative impact on testing accuracy.
No instrument failure was triggered by water contamination throughout the year.
Currently, this flexible square container has become the exclusive storage solution.
It is fully promoted for all high-purity water storage work in the QC laboratory.
