Endotoxin-Free Water for Reliable Bacterial Endotoxin Testing (BET)
Endotoxin-Free Water is an essential reagent used throughout bacterial endotoxin testing (BET) workflows. It is commonly used for reagent reconstitution, sample dilution, positive product control preparation, and routine laboratory testing.
Even trace levels of endotoxin contamination in water can lead to inaccurate results, assay interference, failed validations, and unnecessary investigations. Using certified endotoxin-free water helps laboratories maintain test integrity, regulatory compliance, and confidence in analytical results.
Regulatory Compliance
Manufactured and controlled to support bacterial endotoxin testing requirements in pharmaceutical, biotechnology and medical device laboratories.
Reagents Reconstitution
Used for the reconstitution of Limulus Amebocyte Lysate (LAL) reagents and recombinant endotoxin testing reagents.
Sample Preparation
Suitable for sample dilution, standard curve and Positive Product Control (PPC) preparation for endotoxin recovery studies.
Why Laboratories Use Endotoxin-Free Water
Endotoxin-Free Water is routinely used in quality control and microbiology laboratories performing bacterial endotoxin testing.
Applications include:
- Reconstitution of LAL reagents
- Recombinant Factor C (rFC) assays
- Recombinant Cascade Reagent (rCR) assays
- Positive Product Controls (PPC)
- Sample dilution
- Validation and verification studies
- Routine endotoxin monitoring
Using water that contains endotoxin contamination may result in false positive outcomes and compromised assay performance.
Why Purified Water is not suitable?
| Ordinary Purified Water | Endotoxin-Free Water |
| May contain endotoxin contamination | Tested and controlled |
| Unsuitable for BET | Suitable for BET |
| Risk of false positives | Supports reliable testing |
| Not intended for assay preparation | Intended for assay preparation |
Steps on using Endotoxin-Free Water for Analysis
Step One: Preparation with Endotoxin‑Free Materials
All glassware, consumables, and especially water used for reagent preparation must be certified endotoxin‑free to eliminate contamination risks before testing begins.
Step Two: LAL Assay Execution
The Lyophilized Amebocyte Lysate (LAL) test is performed using validated methods to detect and quantify endotoxins with high sensitivity and specificity.
Step Three: Accurate Results and Compliance
Results are analyzed against regulatory thresholds to confirm compliance, ensuring products are safe and free from harmful endotoxin contamination.
