Celeris®: Preclinical visual electrophysiology
From rodents to rabbits, Celeris delivers a superior preclinical visual electrophysiology experience. Its patented Light Guide electrode-stimulator simultaneously delivers light stimuli and records neural activity. This breakthrough design enables high-throughput ERG and VEP testing with ease and simplicity.
Simplified design
Celeris condenses the requirements of preclinical electrophysiology into one sleek device which contains a red positioning light for use in dark rooms and a built-in heating pad to maintain animals’ body temperature.
Discover CELERIS
Celeris is the preferred choice for rodent and small animal visual electrophysiology! Its sleek design makes preclinical research simple even for novices.

Celeris Light Guide Electrodes
A distinctive feature of Celeris are its light guide electrodes, which integrate stimulation and recording in a single component. In this design, a conductive metal sheath surrounds a light pipe which touches the surface of the eye. This dual-function stimulator-electrode simultaneously delivers light stimuli and records neural activity. 

Visual flash stimulation
The flash stimulators enable standard dark and light ERG, C-wave recordings, flash intensity series, and more.

Visual pattern stimulation
The pattern stimulator enables pattern ERG (PERG), pattern VEP, and multifocal ERG (mfERG).
