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.

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.

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.

How It Works

The stereotaxic nose cone mask functions as a precise anesthetic delivery interface that integrates with standard stereotaxic positioning systems. The mask creates a sealed chamber around the animal's muzzle while allowing proper positioning of the teeth over the incisor bar, maintaining the three-point fixation system essential for stereotaxic accuracy.

Anesthetic gases flow through the inlet port into the mask chamber, where they are inhaled by the animal. The scavenging system removes excess gases through the outlet port, preventing accumulation in the surgical environment. In passive systems, collinear ports direct gases through charcoal canisters for absorption. Active systems utilize separate inlet and outlet ports positioned on opposite sides of the mask, enabling connection to powered evacuation systems for more efficient gas removal.

The mask design ensures consistent anesthetic concentration delivery while minimizing dead space and providing adequate ventilation. Proper mask positioning maintains the stereotaxic coordinate system integrity by securing the animal's head in the correct orientation relative to the frame's reference points.

Features & Benefits

Mouse and rat frame-mask variants

Lets the lab choose below-18 g mouse, 18-45 g mouse, below-300 g rat, or above-300 g rat configurations around the animal model.

Active inlet/outlet gas path

Supports anesthesia delivery and outlet routing toward evacuation or scavenging at the stereotaxic frame.

Incisor and nasal-bridge stabilization

Helps coordinate mask fit with the head-stability needs of mouse and rat stereotaxic work.

Compact cranial-access profile

Keeps the mask body small so cranial, injection, imaging-preparation, and microscope-adjacent workflows remain accessible.

Feature	This Product	Typical Alternative	Advantage
Scavenging Options	Both passive (collinear ports) and active (separate non-collinear ports) configurations available	Many models offer only single scavenging type	Allows laboratories to select masks matching their existing ventilation infrastructure without system modifications.
Species-Specific Sizing	Five distinct size ranges from neonatal rats under 30g to adult rats over 300g	Universal sizing or limited size options	Ensures proper seal and gas delivery efficiency across different research animal sizes.
Frame Integration	Designed specifically for stereotaxic frame compatibility with proper cone orientation	Generic masks requiring custom mounting solutions	Maintains stereotaxic coordinate accuracy while simplifying setup and reducing positioning errors.
Port Configuration	Collinear ports in passive masks, separate non-collinear ports in active masks	Standard inlet/outlet arrangements	Optimizes gas flow patterns for each scavenging method to improve safety and anesthetic delivery consistency.

This mask system provides comprehensive species sizing and dual scavenging options specifically engineered for stereotaxic frame integration. The design maintains coordinate system accuracy while accommodating different laboratory safety requirements through passive and active gas management configurations.
