Sievers Eclipse Bacterial Endotoxins Testing (BET) Platform
Breakthrough BET technology that delivers automation and compliance
The innovative Sievers Eclipse automated endotoxin detection platform decreases assay setup time by up to 85% and reduces Limulus Amebocyte Lysate (LAL) reagent use by up to 90% while meeting all requirements of the harmonized pharmacopeia: USP <85>, EP 2.6.14 and JP 4.01. Through groundbreaking?technology, the Eclipse endotoxin testing solution significantly decreases pipetting steps, reduces operator-to-operator variability, and simplifies BET test setup. The Eclipse platform leverages precise microfluidic liquid handling and embedded endotoxin to automate kinetic chromogenic assays. Throughput of 21 samples per plate is maintained without the complexity of robotics or the time and technique demands of a traditional LAL test.

Compliant, consistent, and conscious bacterial endotoxin testing equipment and services
At Veolia, We believe in making complex measurements simple.
For years, endotoxin testing has required well-trained technicians to carefully prepare samples and standards for gel clot and 96-well plate-based assays. These analytical approaches are slow to prepare, prone to error and retests, and don’t meet the latest data integrity guidelines. While these methods benefit from the sensitivity and specificity of Limulus amebocyte lysate (LAL) for the detection of endotoxins, there is a desire to decrease the use of LAL reagents. This is because LAL is created from the blood of horseshoe crabs, and we all want to conserve and optimize the use of this resource as much as possible.
Now, there’s an easier way to achieve compliant endotoxin testing and improve sustainability with a new compendial endotoxin assay using microfluidics. It simplifies test setup, decreases retest rates, fully complies with the latest data integrity guidelines, and reduces LAL usage by up to 90%.

Frequently Asked Questions (FAQs) for Bacterial Endotoxins Testing?
-
What is bacterial endotoxin testing?
-
Bacterial endotoxin testing is a critical quality control procedure used in the pharmaceutical, medical device, and biotechnology industries to detect and quantify the presence of endotoxins in various products. Endotoxins are components of the outer cell membrane of gram-negative bacteria and can cause severe immune responses in humans and animals, even in small amounts.
-
What are bacterial endotoxins?
-
Bacterial endotoxins are found in the outer membrane of the cell wall of Gram-negative bacteria. The endotoxin effect from Gram-negative bacteria is primarily due to the Lipid A component of lipopolysaccharides (LPS), which can exert pyrogenic (fever-inducing) responses that can be dangerous and even fatal when found in the bloodstream and other body fluids above certain concentrations. Because certain pharmaceuticals and medical devices enter the bloodstream, endotoxin testing is required in those industries. Due to its potent toxicity and effect on patient safety, endotoxin is globally regulated by the US FDA and international pharmacopoeia for any life sciences product that will come in contact with human and/or animal blood.
-
Why would you test for bacterial endotoxins in water or final products?
-
Within the pharmaceutical, medical device, and other life science industries, testing for endotoxins is critical for patient safety and quality control. Endotoxin tests are performed on pharmaceutical-grade water systems, including water for injection (WFI) that is used as ingredient water, and finished products such as drug, animal drug, biological, and medical device products. Pharmaceutical and medical products tested include parenteral drug products (administered through injection, such as intravenous, subcutaneous, intramuscular, and intradermal) and medical devices that have direct or indirect contact with the blood, cardiovascular system, lymphatic system, or cerebrospinal fluid. Global pharmacopoeia (USP <85>, EP 2.6.14 and JP 4.01) describe requirements for Bacterial Endotoxins Testing (BET) and endotoxin limits. FDA guidance provides recommendations for biological product, drug, and device manufacturers on current thinking concerning testing recommendations and acceptance criteria covered in compendial procedures.
-
How does the bacterial endotoxin test method work?
-
For almost 40 years, the US FDA has accepted the Limulus amoebocyte lysate (LAL) test as a finished product test for endotoxins. This is in lieu of rabbit pyrogen testing and is an in vitro assay that can detect presence and concentration of bacterial endotoxins. In LAL tests, the lysate from the blood of horseshoe crabs (Limulus Polyphemus) reacts with bacterial endotoxins to indicate the presence of endotoxins in a sample. There are three bacterial endotoxin test principle methodologies for LAL testing: gel-clot, turbidimetric, and chromogenic. In the gel-clot method, LAL and sample are mixed, followed by the operator screening for gel formation in the reaction tube. The results are from a subjective interpretation of the clot formation, and thus the gel-clot method is a qualitative test. In turbidimetric and chromogenic methodologies, samples are mixed with LAL reagent, and the color change or turbidity are measured over time. Chromogenic and turbidimetric LAL assays are quantitative and demonstrate the amount of endotoxin present. Results are calculated from a standard curve. Endotoxin limits and requirements for conducting BET are described in global pharmacopeia, USP <85>, EP 2.6.14 and JP 4.01. A new general chapter in the European Pharmacopoeia describes a method for BET using recombinant factor C (rFC) instead of the classic LAL-based method.
-
How much LAL reagent is used with the Sievers Eclipse BET Platform?
-
With just 1 mL LAL reagent, 21 samples?can be?run?on the Eclipse?platform. By decreasing horseshoe crab (HSC) lysate use by up?to 90%, the Eclipse reduces the demand of this valuable natural?resource and delivers a fully compliant BET assay that the global HSC population can sustain.
-
Is the Sievers Eclipse BET Platform compliant?
-
Yes. The Eclipse platform uses commercially available, FDA-licensed LAL and meets all requirements of the harmonized global?pharmacopoeia, USP <85>, EP 2.6.14, and JP 4.01.?Bacterial endotoxin testing with the Eclipse platform includes minimum three-point standard curve in duplicate using standardized endotoxin; samples and PPCs in duplicate; negative controls in duplicate; analyst and lysate lot qualification in triplicate; use of FDA licensed LAL. It also complies with 21 CFR Part 11 and data integrity guidelines.
-
Are standard curves automated with the Sievers Eclipse?
-
Yes.?Traditionally, for?compliant endotoxin assays, the?end user must construct at least a three-point standard curve in?duplicate from a stock vial of standardized endotoxin; must have?duplicate negative controls; and must run each sample in duplicate?with a PPC, also in duplicate.?With the Sievers Eclipse BET Platform, these steps are automated?using?preloaded endotoxin standards spanning up to?a five-point standard curve and preloaded PPCs. Therefore,?all the end user?must?do is load Water for BET and samples onto the plate with no?additional prep work. The result is the ability to set up the assay in?9?minutes,?compared to upwards of 60 minutes that other platforms?require.??
