Tuolumne

Quad Amplifier Module

For many cutting-edge applications in flow cytometry, off-the-shelf components do not meet your exacting requirements. Whether you’re customizing an existing cytometer or building your own, the Tuolumne will simplify the process. The Tuolumne quad transimpedance amplifier module provides fixed-gain signal amplification to suit your needs.

Designed to work with both traditional PMTs as well as Silicon Photomultipliers (SiPMs), the Tuolumne allows you flexibility in customizing your instrument. This standalone unit is compact and easy to use, with simple I/O and power connections for plug-and-play convenience. The Tuolumne delivers excellent performance at low cost in a small, lightweight package.

The Tuolumne provides low noise amplification of output from PMTs or other devices that require an amplified current-to-voltage signal. It offers a broad input signal range, and a simple flip of a switch allows for inverted output signal. The Tuolumne comprises a 4-channel amplifier board in a compact housing, with I/O provided through SMA-type connectors for easy hook up.

The Tuolumne puts the performance of your flow cytometer in your hands.

The Tuolumne is a compact (9” x 8.5” x 3”) quad port PMT amplifier module for use in flow cytometry applications.
