Description
The Biofargo Tail Vein Injection Apparatus with Mouse Restrainer is designed to improve vein visualization and animal positioning during mouse tail vein injections. A built-in 3 W yellow LED illuminates the lateral tail veins, while the restraint and pressure system helps keep the mouse stable and makes the vessels easier to access during intravenous (IV) administration.
Researchers searching for restrainer mice solutions typically need two functions: secure animal positioning and clear access to the tail vein. This integrated mouse restrainer provides both in one compact device, helping reduce movement, improve injection-site visibility, and support more consistent procedures across operators.
Designed for mice weighing 17–40 g, the apparatus includes interchangeable 25 mm and 30 mm rodent fixation tubes. It is suitable for laboratories performing routine mouse IV dosing, preclinical research, gene-delivery studies, vaccination research, and disease-model experiments.

Why Researchers Choose This Mouse Restrainer
-
Integrated mouse restraint: interchangeable fixation tubes help limit animal movement and maintain stable positioning throughout the injection procedure.
-
LED vein visualization: the built-in 3 W yellow LED illuminates the lateral tail veins and can improve visibility when veins are difficult to locate under ambient laboratory lighting.
-
Improved tail access: the restraint and pressure system helps present the tail in a consistent position for needle placement.
-
Visual needle-placement support: direct observation of the illuminated vein helps operators assess needle positioning during injection.
-
Suitable for routine workflows: the combined mouse restrainer and illuminator reduces the need to coordinate separate restraint and lighting devices.
-
Multiple fixation sizes: included 25 mm and 30 mm tubes accommodate mice of different body sizes within the specified 17–40 g range.
LED Mouse Restrainer vs. Manual Restraint vs. Heated Platform
Compare common mouse tail vein injection setups by vein visualization, animal restraint, temperature control, and intended use.
| Comparison | BF-40 LED Mouse Restrainer | Manual Restraint | Heated Platform |
| Vein Visualization | Built-in 3 W yellow LED illuminates the lateral tail veins | Depends on ambient light, mouse strain, and operator experience | Controlled warming may help dilate the tail vein; illumination depends on the model |
| Animal Restraint | Dedicated mouse fixation tubes support stable positioning | Manual handling or a separate mice restrainer is required | Restraint features vary by platform and model |
| Active Heating | No | No, unless a separate warming method is used | Yes, on applicable models |
| Animal Compatibility | Designed for mice weighing 17–40 g | Depends on the restraint method | Depends on the platform specifications |
| Best Suited For | Routine mouse IV injections requiring LED vein visualization and stable restraint | Experienced operators, occasional procedures, or laboratories with an existing restraint system | Protocols that specifically require controlled tail warming |
Applications

FAQ
What is the Biofargo tail vein injection apparatus used for?
It combines a mouse restrainer with a 3 W yellow LED illuminator to support stable positioning and improved lateral tail vein visualization during mouse intravenous injection procedures.
Can this device be used as a restrainer for mice?
Yes. The system includes interchangeable 25 mm and 30 mm mouse fixation tubes designed to restrain mice weighing 17–40 g while keeping the tail accessible for injection.
How does the LED improve tail vein visualization?
The 3 W yellow LED illuminates the tail and helps the lateral veins stand out from surrounding tissue, reducing dependence on ambient laboratory lighting.
What size mice does the restrainer accommodate?
The apparatus is designed for mice weighing 17–40 g and includes 25 mm and 30 mm fixation tubes for different body sizes.
Does the BF-40 actively heat the mouse tail?
No. The BF-40 uses LED illumination and a restraint/pressure system but does not provide active heating. If a protocol requires controlled warming, use an approved separate warming method in accordance with institutional animal-care procedures.
What are the power requirements?
The included adapter accepts AC 100–220 V at 50 Hz and provides DC 12 V, 2 A output.
