250 µm/turn – Carefully target brain layers with the oDrive’s high accuracy.
Right-sized for different animal models – The oDrive comes in four sizes ranging from oDrive-2.5 for small animals or rodents, up to the oDrive-10 for larger brains and animals.
Lightweight – The oDrive-2.5 weighs 0.55 g, while the oDrive-10 weighs 0.95 g.
Fiber options – Select from four different optical fiber options to match your needs. See the specifications for more information.
Simplified implant – NeuroNexus worked closely with labs to develop a low-risk implant procedure. Ask us for a demonstration video!

The oDrive-2.5 is optimized for applications where an exceptionally small and lightweight microdrive solution is needed.

Drive range: 2.5 mm
Height: 11.9 mm
Weight: 0.55 g

In addition to its reduced size, the oDrive-2.5 incorporates improvements to enhance its usability and practicality. NeuroNexus recommends the oDrive-2.5 for researchers performing chronic recordings in mice, birds, and other small animal models.

The oDrive-5 is suitable to the widest variety of applications in rodents or similar animal models. With a drive range of 5 mm and a weight of 0.65 g, the dDrive-5 provides enough probe depth adjustment for extended experiments, but remains light enough even for mice.

Drive range: 5 mm
Height: 16.9 mm
Weight: 0.65 g

With an extended drive range of 7.5 mm, the oDrive-7.5 is most suited to larger animal models, or applications where a wide range of probe movement is desirable.

Drive range: 7.5 mm
Height: 21.9 mm
Weight: 0.80 g

With 2.5 mm more drive range than oDrive-7.5 mm, the oDrive-10 is capable of safely housing a full 10 mm probe.

Drive range: 10 mm
Height: 16.4 mm
Weight: 0.85 g

oDrive-2.5/ oDrive-5/ oDrive-7.5 / oDrive-10	Full oDrive kit (probe mounted unless otherwise specified)
oDrive 5-pack
oDrive Screwdriver	Mounts to the drive screw to advance or retract the probe.
IST-Adpt	Mounts to a stereotaxic frame (for Kopf 7.9 mm)
IST-2mm	2 mm rod connects oDrive package to IST-Adpt for implant

Further Information (Please read before ordering; contact us with any questions):

The oDrive ships with the probe fully retracted. To perform the initial advancement of the probe, turn counterclockwise; failure to do so will strip the drive screw. (This only applies when the oDrive is in the fully retracted position.)
When ordering a probe longer than the oDrive drive range, the excess length will protrude past the base. For example, a 5 mm probe on an oDrive-m (2.5 mm drive range) will ship with 2.5 mm of the probe protruding.
The optical fiber can be terminated with approx. 50 µm accuracy anywhere along the probe shank. Any sites obscured by the fiber will not function.
When ordering 15 µm-thin multi-shank designs, the shank with the fiber attached will be slightly out of alignment with the other shanks.
Any internal reference sites on electrode arrays will not function with an attached fiber.
The default fiber is our 105 µm I.D./125µm O.D., 0.22 NA option. However, when ordering a narrow shank probe such as the Buzsaki design, the 50 µm I.D./62.5 µm O.D., 0.22NA fiber will be supplied.
Each assembly is custom. Please specify your desired fiber termination location along the probe shank.

A dDrive surgical video guide is available to guide you through the implant procedure. The oDrive procedure differs slightly at the end of the surgery, but the dDrive video should give you a good idea of what to expect. Please contact us for access.
