We've tabled our classic Quintessential Stereotaxic Injector (QSI™) to provide an even more versatile injector suited for stereotaxic surgeries. 

If you already own a QSI add the Tabletop system by simply purchasing the Tabletop Injector Only (53327).

Precision you can program. Flexibility you can expand. Control you can trust. 

Stoelting's classic QSI™ (Quintessential Stereotaxic Injector) is the gold standard for automated stereotaxic infusion and withdrawal for modern neuroscience research.

The QSI™ delivers precise, programmable infusion and withdrawal of volumes from the nanoliter to microliter range. Designed for flexibility and ease of use, the QSI™ provides researchers with accurate control over injection volume and flow rate while supporting single- or dual-injection workflows.

From nanoliter injections to microliter-scale delivery, the QSI™ combines automated control, broad syringe compatibility, integrated illumination, and an intuitive touch-screen interface in one versatile stereotaxic injection platform.

WHY CHOOSE THE QSI™?

• 1 nL Precision - Set injection volumes as small as 1 nanoliter, with flow rates ranging from 0.001 µL/min to 363 µL/min.
• Single or Dual Injection - Control one or two independent injections with the QSI™. Start with a single injector and expand to dual injection capability as research needs evolve.
• Simple Touch-Screen Control - The intuitive touch-screen controller allows researchers to program: Injection volume, Flow rate, Syringe specifications, Infusion or withdrawal parameters
• Built-In LED Illumination - Integrated LED lighting provides low, medium, and high intensity settings, controlled directly from the touch screen.
• Broad Syringe Compatibility - The QSI™ accommodates Hamilton syringes from 0.5 µL to 250 µL and includes a library of common syringe specifications for convenient setup.

The QSI™ is part of Stoelting's SMART HUB family. The SMART HUB seamlessly integrates control of, not only your QSI™ but also a warmer, surgical drill, and even the stereotaxic instrument. From the single, intuative interface you control everything streamlining, organizing and fully synchronizing your surgical environment. To add our Warmer or Drill with auto-stop functionality to your QSI, you need only purchase 59900WRM (SMART HUB Warmer) or 59900DRL (SMART HUB Drill).
