Overview
The Stereotaxic Nose Cone Masks family provides compact mouse and rat anesthesia interfaces for stereotaxic surgery and other frame-based workflows where gas delivery, head stability, and cranial working access have to be planned together. The family includes mouse options for below-18 g and 18-45 g animals, plus rat options for below-300 g and above-300 g workflows.
Unlike a general bench cone mask, this mask family is designed around stereotaxic positioning. The inlet and outlet paths support an active anesthesia workflow, letting the outlet connect toward evacuation or scavenging so anesthetic delivery and waste-gas routing can be planned at the frame. The compact mask bodies help preserve access around the head during cranial surgery, injection, imaging preparation, or microscope-guided work.
The source design also addresses head stability at the mask. Mouse configurations use an incisor-support path in the conical nose cavity with an added spring block for head stabilization. Rat configurations use an adaptor opening for incisor fixation while the mask cavity supports the nasal bridge. That makes the mask selection part of the animal-positioning decision, not only a gas-delivery accessory.
Scientific Use
Stereotaxic procedures often require a stable head, a clear cranial field, steady inhalation anesthesia, and a practical scavenging path in the same small workspace. These masks are useful when labs are coordinating stereotaxic surgery, intracranial injection, cranial window preparation, viral delivery, cannula implantation, electrode or fiber placement, or microscope-adjacent preparation around mouse and rat head geometry.
Buying Fit
Choose this page when the lab needs an anesthesia mask that works at the stereotaxic frame. Choose general cone masks for non-frame bench maintenance, and choose concentric tubing masks when flexible pad or table-top positioning is more important than frame-mounted nose-cone geometry. Complete the station with a compatible anesthesia machine, vaporizer, flowmeter, active scavenger or absorber path, warming, monitoring, and the selected stereotaxic frame or holder set.

Practical Tips
Select the mask by species and weight range before finalizing the frame setup.
Why: The source family separates below-18 g mouse, 18-45 g mouse, below-300 g rat, and above-300 g rat options.
Plan the outlet path with the active scavenger or absorber at the same time as the mask.
Why: The mask value depends on pairing anesthesia delivery with practical waste-gas collection at the frame.
Check that the selected mask leaves enough cranial access for drilling, injection, holder approach, or microscope clearance.
Why: The source design emphasizes compact mask dimensions for head surgery workflows.

Compliance
Which animal sizes are supported?
The source family includes mouse masks for below-18 g and 18-45 g animals, plus rat masks for below-300 g and above-300 g animals.
Why use a stereotaxic nose cone instead of a general cone mask?
Use a stereotaxic nose cone when the mask needs to work at the frame while preserving cranial access, head stability, and inlet/outlet gas routing.
How does the active gas path help the station?
The inlet supplies anesthetic gas while the outlet can be routed toward evacuation or scavenging, helping the anesthesia and waste-gas path stay organized at the frame.
What should be ordered with these masks?
Plan the anesthesia machine, vaporizer, flowmeter, tubing, active scavenger or absorber path, warming, monitoring, stereotaxic frame, and holder accessories around the final setup.
How do I choose between the mouse and rat styles?
Select by species, weight range, and how the frame supports incisors, nasal bridge positioning, ear bars, and cranial working access.
