Instech Laboratories VABMG Magnetic Mouse Vascular Access Button Handling Tool – Premium Anodized Aluminum, Forked Removal Tip, Magnetic Capture Core, Refined Animal Welfare Control (MPN: VABMG) The Instech Laboratories VABMG (also cataloged under global surgical distribution networks as VABMG-EACH or NC1265533) is a premium, preclinical-grade microsurgical handling instrument engineered to facilitate steady, low-stress interactions with transcutaneous implants in laboratory mice. Precision-machined from high-grade anodized aluminum (typically finished in a distinctive purple or blue visual cohort profile), this specialized pen-style wand features an integrated internal neodymium magnet coupled with a mechanical forked extraction tip. Designed explicitly to interface with Instech's 1-Channel and 2-Channel Magnetic Mouse Vascular Access Buttons™ (VAB), the tool establishes a secure magnetic connection to hold the implanted button steady during dosing or flushing protocols. This entirely removes the need for sharp steel hemostats or mechanical clamps, dramatically enhancing procedural safety while protecting both the delicate transcutaneous device and the animal from physical trauma. Technical Performance and Animal Welfare Refinement Hemostat-Free Magnetic Stabilization: Outfitted with a high-coercivity internal magnetic core that generates an immediate, secure physical bond with the mouse VAB. By utilizing magnetic capture rather than rigid mechanical teeth, the tool eliminates the risk of scratching the button stalk, crushing the injection ports, or pinching the animal's skin. Dual-Purpose Forked Extraction Tip: The operational end of the tool features a specialized precision-machined mechanical fork. This fork slides smoothly underneath attached magnetic tethers or protective aluminum group-housing caps (e.g., VABM1C or VABM2JC), using smooth lever counter-leverage to disengage strong magnetic seals without applying painful downward force or pulling on the animal's healing subcutaneous anchoring disk. Tactile Pen-Style Silhouette: Precision-balanced and styled as a knurled ergonomic wand. This shape provides micro-surgeons and vivarium technicians with high control, permitting single-handed attachment swaps while the other hand comfortably secures the animal during laboratory procedures. Autoclavable Metallurgy Matrix: Fabricated from high-purity, laboratory-grade aluminum treated with a hard anodized finish. The instrument retains full structural and magnetic properties through strict chemical wipe-downs and repetitive laboratory steam autoclaving cycles up to 121 C. Product Specifications Catalog Number / MPN: VABMG (Cross-listed as VABMG-EACH / NC1265533) Manufacturer / Brand: Instech Laboratories, Inc. Instrument Classification: Preclinical Vascular Access Button (VAB) Handling and Cap Removal Tool Device Compatibility Baseline: Instech Magnetic 1-Channel and 2-Channel Mouse Vascular Access Buttons (VABM series models) Material Composition: Premium Hard-Anodized Aluminum Handle with integrated internal Neodymium permanent magnets Color Coding Finish: Blue / Purple metallic anodization (Ensures rapid identification in surgical instrumentation kits) Sterility Metric: Shipped Non-Sterile (Fully validated for standard autoclave decontamination loops prior to clean room or barrier facility deployment) Standard Packaging Configuration: Sold individually (1 tool per pack) or as surplus multi-sets Key Benefits and Applications Aseptic Syringe Dosing and Flushing: Operates as an unyielding extension handle that stabilizes the mouse VAB during syringe-injector engagement, ensuring a clean, leak-free PinPort™ interface without pressing down onto the mouse’s back. Continuous Tether Connection Shifts: Simplifies daily transitions between group-housed protective caps and active infusion spring tethers on automated pharmacokinetic track setups, optimizing high-throughput laboratory throughput. Refined Laboratory Stress Mitigation: Minimizing mechanical friction and localized pulling at the subcutaneous catheter site dramatically reduces animal agitation, lowering stress-induced corticosterone spikes during serial blood sampling runs. Implant Patency Extension: Preventing physical alignment scuffs and mechanical alignment warping on the port perimeter ensures a longer functional lifespan for the transcutaneous device across multi-week physiological tracking studies.
