Product Profile

The Toxinometer® ET-7000 is a computer-operated kinetic incubating tube reader, which is exceptionally user-friendly and easily expandable. Depending on the number of samples to be processed, our state of the art expansion modules can be connected to allow for endotoxin testing in a wide range of fields and sample quantities. The temperature setting can be switched between 30 and 37 ℃, facilitating (1 → 3)-β-D-glucan and peptidoglycan test for research projects.


  • A single assay module can simultaneously measure up to 16 samples
  • Up to 8 measurement modules can be connected to the unit to enable simultaneous measurement of 128 samples.
  • The Toxinometer® can test using both multi test and single test reagents

Main Specification

  • Light source : High intensity blue LED (Central wavelength: 430 nm)
  • Temperature control : 30/37 ℃(Set using the software)
  • Measurement time : Max. 200 min

Toxinometer® Measurement Principle

Light from an LED goes through the reaction tube filled with reaction mixture via aperture diaphragm 1.

The light passes through the reaction mixture and then, while coming through aperture diaphragm 2, is detected by the silicon photocell.


Toxinometer® translates the reaction of the LAL reagent with endotoxin into changes in the light intensity transmitted at 430 nm. The light intensity remains constant for a while after the start of reaction, but gradually decreases as the reaction proceeds, and stops upon completion of the reaction.

The ratio of the light intensity l(t) to the light intensity at an early stage of reaction lo is defined as R(t), and the threshold R(th) of R(t) is determined. Based on this, Toxinometer® reads the period from the start of the reaction to the point at which R(t) reaches R(th) as the gelation time Tg or the activation time Ta.

R(t) = [l(t)/lo] x 100 %



A correlation between the endotoxin concentration and gelation time (Tg) is obtained, and the endotoxin concentration is calculated using the gelation time of a sample.
