Frequently Asked Questions

Which batch COA is available for bacteriostatic water and which parameters are tested?

Each batch of EONA Bacteriostatic Water is documented by a batch-specific Certificate of Analysis (COA). Tested parameters: sterility, pH value, particle freedom, and benzyl alcohol concentration (0.9%). The COA can be accessed directly on the product page.

What is the difference between bacteriostatic water and plain sterile water in a laboratory context?

Sterile water (WFI) contains no preservative and is designed for single use in the laboratory. Bacteriostatic water contains 0.9% benzyl alcohol, which inhibits the growth of bacteria in an opened laboratory vial. It is suitable as a standard solvent for lyophilized research substances when multiple withdrawals are made using sterile laboratory techniques.

Why does bacteriostatic water contain 0.9% benzyl alcohol, and what is the function of this additive?

The addition of 0.9% benzyl alcohol has a bacteriostatic effect: it inhibits the growth of bacteria in an opened laboratory vial. This makes the water suitable as a standard solvent for lyophilized research substances when multiple withdrawals are made over a period of time using sterile laboratory techniques. The exact benzyl alcohol concentration is indicated in the batch-specific COA.

Is the purchase and shipping of bacteriostatic water within the EU legal and duty-free?

Yes. Bacteriostatic water is not a regulated or controlled substance. EONA ships from an EU warehouse, and no customs duties apply within the European Economic Area. Delivery typically takes a few business days.

How should bacteriostatic water be correctly stored as laboratory accessory?

Store cool (2 to 8 °C), dry, and protected from light. Handle vials in the laboratory after opening according to applicable laboratory standards. All information applies exclusively to research use.

What size containers does EONA offer, and is there a price advantage for bulk purchases?

EONA offers Bacteriostatic Water in 10 ml SKUs in quantity discounts of 1, 3, 5, and 10 vials. The unit price decreases with higher quantities, making larger laboratory orders more cost-effective.

How does EONA differ from suppliers like Eurochem or Particle Peptides for laboratory accessories?

EONA provides a complete COA for each batch (sterility, pH value, particle freedom, and benzyl alcohol concentration), which can be viewed directly on the product page. Shipping is from an EU warehouse without third-country risk. EONA applies the same quality framework to its entire product range, not just individual products.
