Thomas RECORDING offers a broad range of Injection Cannulas for Microinjections in Neurophysiological Applications – the ideal tool for accurate and reliable drug delivery in neurophysiological research applications. Designed to meet the rigorous demands of neurophysiology, these high-quality cannulas are available in both glass and metal materials, offering optimal performance for a wide range of applications. Thomas microinjection pipettes are available for use with Thomas Microdrive systems (e.g. Mini Matrix, Eckhorn Matrix) or for other microdrives or manual electrode manipulators. We customize our products to meet your requirements. Please feel free to contact us for your individual cannula design. 

Product Description

Key Features

• Versatile Material Options: Choose from ultra-clear quartz glass for precise visibility and sterilization, or durable stainless steel for enhanced strength and rigidity in demanding environments.

• Multiple Outer Diameters: Available in a variety of sizes to accommodate different injection requirements and provide flexibility in your research methods. Glass pipettes are avaialble with pulled and ground or only ground tip shapes.  

• High Precision: Engineered for microinjection, ensuring accurate, localized delivery with minimal tissue disturbance.

• Ideal for Neurophysiology: Perfect for intracerebral, spinal, or peripheral injections, enhancing the quality and consistency of your experimental procedures.

Examples of TREC Microinjection Cannulas

Thomas microinjection technique uses either a metal needle or a quartz glass micropipette together with a microinjection pump to inject small liquid volumes. Typically a stereotaxic setup may be required. The Thomas microinjection pipettes are available for Thomas Fiber Microdrive systems (e.g. Mini Matrix, Eckhorn Matrix or Thomas Matrix) or for other motorized (e.g. Thomas MEM systems) or manual microdrives.

Pipettes for TREC Fiberelectrode Manipulators

Microinjection pipettes for the Thomas microdrives are equipped with the patented Thomas rubber tube drive that allows to load the pipette to a Thomas Mini Matrix or Eckhorn Matrix drive (see figure 1 and 2). Microelectrodes and pipette are moved by the rubber tube of the microdrive to place them with micrometer precision in the animal´s brain or in a brain slice. The microinjections for the Thomas microdrives are available with stainless steel of quartz glass pipette material. We are stringent with quality parameters, only microinjection pipettes that pass the strict quality standards are released as final product.

Pipettes for other Manipulators

Microinjection pipettes for other than Thomas fiberelectrode microdrives are also made of quartz glass or stainless steel. These microinjection pipettes (OD=100-120µm) are strengthened with an additional glass pipette (OD= 0.5, 1.0, 1.5 or 2.0mm) or a stainless steel tube (OD=305µm) so that you can clamp it to an electrode holder clamp of an electrode manipulator.
