The Manual Micro-Push Stereotaxic Injector is a precision mechanical injection system designed for accurate delivery of small volumes during stereotaxic procedures. This holder accommodates syringes ranging from 0 to 1000 μL capacity and provides controlled micro-injection with a 25 mm stroke length. The system enables precise volume delivery from 0 to 416.9 μL with fine adjustment capability of 0.167 μL per small grid movement.
The injector integrates with standard stereotaxic frames to facilitate targeted delivery of drugs, viral vectors, tracers, or other experimental compounds to specific brain coordinates. The manual micro-push mechanism allows researchers to control injection speed and pressure, critical factors for maintaining tissue integrity and ensuring accurate substance placement in neural structures.
How It Works
The manual micro-push stereotaxic injector operates through a precision mechanical advancement system that provides controlled linear movement of the syringe plunger. The 25 mm stroke mechanism allows for graduated volume delivery by translating rotational input into precise linear displacement. Each small grid movement corresponds to 0.167 μL volume change, enabling fine control over injection parameters.
The holder secures syringes of various sizes (0-1000 μL capacity) within the stereotaxic coordinate system, maintaining stable positioning during injection procedures. The manual operation allows researchers to control injection speed and pressure in real-time, adapting to tissue resistance and ensuring optimal substance delivery. This mechanical approach eliminates electrical artifacts that could interfere with concurrent electrophysiological recordings.

| Maximum Injection Volume | 0-416.9 μL delivery range | Entry-level systems offer smaller volume ranges | Supports both small tracer studies and larger drug delivery protocols |
| Operation Mode | Manual micro-push control | Basic holders require manual syringe operation | Provides controlled advancement without full automation costs |
| Stroke Length | 25 mm advancement range | Shorter stroke lengths limit volume delivery | Accommodates complete volume delivery from larger syringes |
This injector combines precise volume control with versatile syringe compatibility in a mechanical system that eliminates electrical interference. The 0.167 μL resolution and 416.9 μL maximum volume range address most stereotaxic injection requirements.
Practical Tips
Verify volume accuracy by performing test injections with known volumes and measuring delivered amounts gravimetrically.
Why: Ensures accurate dose delivery for experimental reproducibility.
Clean the micro-push mechanism with appropriate solvents after each use to prevent solution buildup.
Why: Maintains smooth operation and prevents volume delivery errors.
Pre-wet the injection system with vehicle solution before loading experimental compounds.
Why: Eliminates dead volume effects and ensures accurate initial dose delivery.
Allow 1-2 minutes after needle insertion before beginning injection to minimize tissue displacement artifacts.
Why: Permits tissue settling and reduces substance backflow along needle track.
If injection resistance increases suddenly, stop and check for needle blockage or tissue compression.
Why: Prevents needle damage and ensures proper substance delivery to target site.
Always verify syringe clamp security before beginning injection procedures.
