The unrivaled Newton 7.0 is ideal for chemiluminescence and bioluminescence, for in vivo and in vitro applications.

The NEWTON 7.0 achieves the best signal to noise ratio for the lowest limits of detection. The system is extremely linear over its wide dynamics and can easily detect large intensity difference between bright and faint bands before reaching saturation. The broad linear dynamic range enables relative quantification of target proteins with confidence.

The NEWTON 7.0 system combines high sensitivity with advanced animal-handling features and userfriendly time-saving operation.

The NEWTON 7.0 proprietary optics have been specifically developed for macro imaging with high light collection capacity, incorporating a unique combination of high numerical aperture and long working distance.

Bright fluorescence observation can be performed in a rapid scanning mode that shortens exposure times and minimizes specimen damage. Observation is thus possible even with slight body movement. The fast lens is also ideal for luminescence applications requiring longer exposure time.

The advent of novel fluorescent probes has increased the demands on in-vivo fluorescence imaging systems to be able to deftly handle a variety of simultaneous signals, specifically in the IR and NIR area. The dual magnetron filter technology ensures transmission above 90% and very narrow band cutting - meaning improved spectral separation and increased sensitivity.

The detection spectral range goes from 400 to 900nm, making the NEWTON 7.0 ideal for GFP, YFP or IR applications. The best spectral range for penetrating an animal is between 600 nm and 900 nm. With NIR and IR fluorescence detection, background is very low, and tissue autofluorescence does not limit performance.


3D Optical Tomography - Unrivalled Precision

3D OPTICAL TOMOGRAPHY – unrivalled precision.

Bioluminescence Tomography (BLT) as well as Fluorescence Molecular Tomography (FMT) are imaging techniques providing further quantitative and localized analyses of a source distribution within a living animal from signals measured on the body surface of the animal.

The NEWTON 7.0 integrates an innovative 3D Tomography imaging module that reconstructs bioluminescent or fluorescent signals into volume that are overlaid within the 3D topographic model of the subject.

For a better understanding of anatomical and deeper tissue structures, the digital organ library allows the superimposition of the mouse organs to the tomographic image to identify the source localization with precision.

Biosthesia - Add-on Anesthesia System



The BIOSTHESIA system has been specially designed for inhalation of isoflurane agents by laboratory animals.

The BIOSTHESIA is a small weight device, compact and robust, which can be used as a standalone unit on a table. As it is transportable, it can be moved from one place to another in no time and can be immediately operational.

The system is composed of a medical grade digital flowmeter, a precision TEC3 format vaporizer, an active charcoal filter, a breathing circuit with mouse nose-cone/mask and an induction box.

The BIOSTHESIA vaporizer is designed to operate with isoflurane and is calibrated using a laser refractometer, to ensure accuracy of use. In addition, our vaporizer has a safety lock function, to prevent accidental turn on – making the BIOSTHESIA vaporizer not only one of the most accurately manufactured and certified vaporizer, but one of the safest.

The BIOSTHESIA could supply at the same time the induction box and the imaging rack for one, two or five mices.
