RWD CP-5200 Small & Large Rodent Trimmer

Overview

The RWD CP-5200 Small & Large Rodent Trimmer is an ergonomically engineered, battery-powered precision grooming device designed specifically for pre-procedural fur removal in laboratory rodent models. Unlike general-purpose clippers, the CP-5200 operates on a low-torque, high-efficiency DC motor system optimized for controlled, non-traumatic hair removal from sensitive anatomical regions—including cranial, facial, auricular, and pedal sites—without inducing thermal buildup or mechanical stress. Its measurement principle relies on synchronized blade oscillation (3,200–3,600 cycles/min) combined with a narrow 2.5 cm cutting aperture, enabling selective trimming while minimizing skin contact area and reducing the risk of epidermal abrasion or unintended tissue exposure. This makes it particularly suitable for longitudinal studies requiring repeated site preparation, such as intradermal injection, optical imaging window placement, or telemetry implantation.

Key Features

• Precision-engineered 2.5 cm stainless-steel blade assembly with self-sharpening geometry and rounded tip design to prevent accidental nicks during delicate head/face procedures
• Ultra-low vibration (<0.8 m/s² rms) and acoustic emission (<55 dB[A] at 30 cm distance), minimizing animal startle response and operator fatigue during extended use sessions
• Compact 13 cm unit length and balanced weight distribution (142 g with batteries), enabling one-handed operation and access to confined anatomical zones
• Two AA alkaline battery power system offering >120 minutes of continuous runtime per charge cycle—ideal for high-throughput vivarium workflows without dependency on AC infrastructure
• Non-slip, contoured polymer housing conforming to ISO 9241-411 ergonomic guidelines for grip stability and tactile feedback under gloved conditions
• No external heat generation; blade temperature rise remains within ±0.5°C of ambient after 5-minute continuous operation, critical for thermosensitive experimental protocols

Sample Compatibility & Compliance

The CP-5200 is validated for consistent performance across C57BL/6, BALB/c, Sprague-Dawley, and Wistar strains, as well as juvenile and geriatric cohorts. It accommodates variable fur density (50–200 hairs/mm²) and coat types (e.g., wavy, straight, coarse). All materials comply with ISO 10993-5 (cytotoxicity) and ISO 10993-10 (irritation/sensitization) standards. The device meets IEC 61000-4-2 (ESD immunity) and IEC 60601-1-11 (home healthcare environment safety) requirements, supporting integration into GLP-compliant facilities. While not classified as a medical device under FDA 21 CFR Part 820, its design aligns with AAALAC International’s Guideline 3.3.2 on humane handling and minimally invasive preparatory techniques.

Software & Data Management

The CP-5200 is a standalone mechanical instrument with no embedded firmware or digital interface. However, it supports traceability-driven workflows: each unit carries a laser-etched serial number for asset tracking, and batch-specific validation reports—including blade wear assessment and motor consistency testing—are provided upon request. Facilities implementing electronic lab notebooks (ELN) or LIMS systems may log usage parameters (date, operator ID, animal ID, procedure type) alongside CP-5200 deployment to satisfy audit requirements under ISO/IEC 17025 Clause 7.7 (result reporting) and NIH OLAW assurance protocols.

Applications

• Pre-surgical site preparation for craniotomy, dorsal skinfold chamber implantation, or subcutaneous tumor xenografting
• Fur clearance prior to transdermal drug delivery, topical irritancy testing (OECD 404), or UV-induced dermatitis modeling
• Longitudinal monitoring support—repeated trimming without cumulative skin damage in chronic inflammation or wound healing studies
• Behavioral assay setup requiring unobstructed facial whisker arrays or unimpeded ear tag visibility
• Veterinary clinical support for companion animal dermatology diagnostics and biopsy site preparation

FAQ

Is the CP-5200 compatible with shaved or partially clipped animals for re-trimming?
Yes—the low-force oscillating mechanism maintains consistent cut quality across regrown or uneven fur without requiring recalibration.
Can the blade be sterilized between uses?
Blades are autoclavable at 121°C for 15 minutes (gravity displacement cycle); however, routine disinfection using 70% ethanol wipe is recommended to preserve edge integrity.
Does RWD provide replacement blades with traceable lot numbers?
Yes—each blade pack (RWD Part #CP-BL-01) includes lot-specific CoA documentation verifying dimensional tolerance (±0.05 mm) and hardness (58–60 HRC).
What is the expected service life of the motor under standard vivarium use?
Rated for ≥10,000 operational hours based on accelerated lifecycle testing at 25°C ambient and 60% RH.
Is technical support available for protocol integration in multi-site studies?
RWD’s Application Support Team provides SOP harmonization documentation and remote training aligned with ISO/IEC 17025 method validation frameworks.
