Sniff-0: Uncover the Power of Smell

Sniff-0 is an olfactometer with an innovative design, feature rich, multi-channel, high-speed, accurate and easily transportable in the form of a rugged wheeled suitcase. The number of channels can be customized according to your needs up to a maximum of 13 + 1 channels, while "tailor made" versions can also be created according to your needs.

Complete Experiment Control and Advanced Configuration Capabilities to reduce configuration times and ensure maximum repeatability of experimental protocols

Compatible with the most common programming platforms and integrated digital input/output trigger channels

Elegant and portable rugged protective case to safeguard your equipment wherever you may want to use it

Breathing Cycle Monitor

Spir-0: Enhance Breathing Analysis

Spir-0 is a compact, easy-to-use breathing activity monitor with a fiber optic sensor compatible with MRI, fMRI, fNIRS and EEG environments. It accurately measures respiratory behavior by detecting air flow variations during breathing. The minimally invasive sensor requires placing a small optical fiber tube at the nostril entrance for automatic calibration and monitoring. Compatible with Sniff-0, it includes software to synchronize odor presentation with the breathing cycle.

Spir-0 uses a fiber optic sensor, making it compatible with MRI, fMRI, fNIRS and EEG environments and applications

The device accurately measures respiratory behavior, providing a detailed representation of the entire respiratory cycle

The sensor is minimally invasive, requiring only that a small optical fiber sensor (less than a millimeter in diameter) be positioned at the entrance of one nostril

Independent gas sources

Sniff-Exp: Expand Your Design Flexibility

Sniff-Exp is an expansion of Sniff-0 that allows you to have two additional independent gas sources (air, CO2, etc). It also allows the use of larger external containers in which to place the odor source.

With Sniff-Exp it is possible to use real foods, while maintaining total control over the quantity and timing of the delivered odor.

Sniff-Exp is fully integrated with Sniff-0 and extends its functionality

The device allows you to have two more independent gas sources and use real odor source items (e.g. food)

Precise synchronization

Response Box 2.0: Open, Flexible, and Future-Proof

The new Response Box 2.0 is now programmable with MicroPython, making protocol design effortless and delivering millisecond precision. Detect visual stimuli onset with screen sensors, capture responses with modular pads, buttons or force sensors, and synchronize via TTL I/O channels with olfactometers, EEG, TMS, fNIRS and many other external devices for robust, real-time experiments.

MicroPython programming streamlines research, letting scientists focus on protocols while ensuring reaction time precision far beyond standard PCs

The new Response Box ensures simple, effective synchronization with EEG recording systems and other devices through its precise trigger input and output capabilities

With the ability to handle multiple digital on/off pads and force sensor options, the Response Box offers maximum flexibility to suit any experimental response measurement needs
