Sievers Eclipse Bacterial Endotoxins Testing (BET) Platform

Breakthrough technology that delivers automation and compliance

The innovative Sievers Eclipse 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 pharmacopoeia: USP <85>, EP 2.6.14 and JP 4.01. Through groundbreaking technology, the Eclipse platform significantly decreases pipetting steps, reduces operator-to-operator variability, and simplifies assay 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 assay.

Compliant, consistent, conscious bacterial endotoxins testing

The Eclipse platform achieves automation and precision in BET assays without sacrificing compliance, reaction biochemistry, or footprint in the lab. Using embedded endotoxin standards and positive product controls (PPCs) with only <30 pipetting steps, the patented Sievers Eclipse microplate delivers automation without the complexity or expense of robotics.

Eclipse Platform Components

  • Analyzer: Absorbance analyzer with consistent incubation control at 37 °C, centrifugal technology, and secure data transmission.
  • Microplate: Precise liquid handling device that achieves automation through innovative microfluidic technology with embedded endotoxin standards and positive product controls (PPCs).
  • Software: Highly customizable enterprise solution with 21 CFR Part 11 and ALCOA+ Data Integrity compliance features.

The Eclipse microplate, in conjunction with the Eclipse analyzer and software, uses centrifugal force and pneumatic chambers to measure and evenly distribute precise amounts of LAL reagent water, samples, and LAL across 104 optical wells. The optical wells comprise segments for standards curves, samples, and PPCs. The reaction is controlled at 37 +/-1 °C, and a high definition view of each well is achieved by obtaining a reading at 405 nm every five seconds.
