LAL Reagent Water ( Water for Bacterial Endotoxins Test )

1. LAL Reagent Water Overview

LAL Reagent Water (Water for Bacterial Endotoxins Test or BET Water or Water for BET ) is specially processed super-purified endotoxin free water is used for Endotoxin test. Its endotoxin concentration is less than 0.003 EU/ml. Various packages, such as 10ml, 20ml, 50ml, 100ml and 500ml per unit, are provided for users’ convenience. LAL Reagent Water (Water for BET) could be used to dilute the assay sample, construct the stand curve, or reconstitute the Lyophilized Amebocyte Lysate reagents.

2. LAL Reagent Water Key Parameter

Endotoxin contamination level: ≤0.003 EU/ml

Water for Bacterial Endotoxins Test is specially processed water is used for endotoxin detection. Its endotoxin concentration is less than 0.003EU/ml. We also provide LAL Reagent Water (water for BET) with endotoxin level less than 0.001EU/ml for the assay sensitivity 0.003 to 5EU/ml kinetic chromogenic assay.

3. Product Features and Application

Endotoxin Free Water (Water for BET, LAL Reagent water, Endotoxin free water or BET water) is specially processed water intended for reconstitution of Lyophilized Amebocyte Lysate and Control Standard Endotoxin (CSE), and to dilute samples and control standards in the endotoxin assay operation.

For reconstitution of Lyophilized Amebocyte Lysate or Amebocyte Lysate, dilution of the test samples and Control Standard Endotoxin, preparation endotoxin free buffers, and construction of the standard curve. 500ml BET water main apply in extract endotoxins from medical devices.

The sensitivity of lyophilized limulus amebocyte lysate (LAL) and the potency of Control Standard Endotoxin (CSE) are verified against USP Reference Standard Endotoxin (RSE).

Our water undergoes both sterilization and depyrogenation purification procedures, complying with LAL reagent water specifications.

Reconstitution of LAL and CSE

Preparation of Standard Curves for Quantitative Assays

Standard curves are mandatory for quantitative endotoxin quantification. LAL reagent water, also referred to as BET water, serves as the diluent for serially diluted CSE standards used to construct calibration curves. Precise curve generation is fundamental to accurate calculation of endotoxin concentrations in unknown test samples.

Sample Dilution

Test articles frequently require dilution to bring their endotoxin levels within the linear range of the calibration curve. LAL reagent water is the designated diluent for sample preparation to preserve testing accuracy.

Negative and Positive Control Preparation

Assay controls are incorporated into every test run to confirm LAL reagent functionality and system validity. All control preparations rely on BET water to guarantee that any measurable endotoxin signal originates solely from the test sample, rather than the diluent.

Assay Reliability & Reproducibility

Consistently high-grade LAL reagent water minimizes experimental deviation and delivers reproducible BET results. Substandard water introduces exogenous endotoxin contamination and measurement bias, compromising overall assay precision.
