Overview
The KUHNE Glass Coverslip Forceps (Model F18001-10) is a precision-engineered laboratory instrument designed specifically for the safe, atraumatic handling of standard and specialty glass coverslips during histological slide preparation, live-cell imaging, microfluidic device assembly, and fluorescence microscopy workflows. Built upon KUHNE’s long-standing expertise in fine-tipped micro-manipulation tools, this forceps employs a calibrated 45° angled tip geometry optimized to minimize lateral slippage and vertical compression forces when gripping fragile 0.13–0.17 mm thick coverslips (No. 1.5). Its 105 mm overall length provides ergonomic control and sufficient reach for use within laminar flow hoods, biosafety cabinets, and inverted microscope stages—without compromising tip stability or tactile feedback.
Key Features
- Angled tip design (45° bevel) ensures optimal contact angle for secure, non-slip engagement with flat glass surfaces—reducing risk of chipping or radial cracking during placement or removal.
- High-precision stainless steel construction (medical-grade 316L alloy) offers corrosion resistance, autoclavability (up to 134°C, 21 psi, 18 min), and long-term dimensional stability under repeated sterilization cycles.
- Ergonomic finger grooves and balanced weight distribution reduce hand fatigue during extended micro-manipulation tasks—critical for high-throughput slide mounting or multi-day time-lapse experiments.
- Tip width ≤ 0.3 mm and tip thickness ≤ 0.15 mm enable precise positioning within narrow microfluidic channels or between densely packed tissue sections.
- Manufactured and quality-controlled by RWD (Shenzhen), a certified ISO 13485:2016 medical device manufacturer—ensuring traceable lot documentation and compliance with Good Manufacturing Practice (GMP) requirements for regulated research environments.
Sample Compatibility & Compliance
The F18001-10 forceps is compatible with all standard optical-grade coverslips (22 × 22 mm, 24 × 50 mm, 24 × 60 mm, and round 12 mm, 18 mm, 25 mm diameters), including borosilicate, fused silica, and polymer-based alternatives (e.g., Zeiss Coverglass, Marienfeld Superior, Ted Pella Ultrathin). It meets ASTM F1529-21 standards for mechanical performance of surgical instrumentation and is validated for use in GLP-compliant histopathology labs and ISO/IEC 17025-accredited testing facilities. Each unit carries a permanent laser-etched model and batch identifier for audit trail integrity.
Software & Data Management
This is a manual, non-electronic instrument; no embedded software, firmware, or digital connectivity is present. As a Class I non-powered surgical instrument per FDA 21 CFR §878.4495 and EU MDR Annex VIII Rule 1, it requires no software validation, cybersecurity controls, or electronic record management. However, its batch-specific manufacturing documentation—including material certifications, surface finish reports (Ra ≤ 0.4 µm), and sterilization validation summaries—is available upon request in English and supports full traceability in regulated quality systems (e.g., LabVantage, SampleManager LIMS).
Applications
- Mounting and repositioning coverslips on paraffin-embedded or frozen tissue sections prior to staining or immunohistochemistry.
- Handling delicate coverslips during live-cell culture chamber assembly (e.g., ibidi µ-Slides, CellView dishes).
- Transferring hydrophilic or plasma-treated coverslips into microfluidic bonding stations without introducing fingerprint contaminants or static charge artifacts.
- Retrieving broken or misaligned coverslips from objective lens paths during confocal or super-resolution imaging sessions.
- Assisting in cleanroom-based fabrication of optofluidic sensors where particulate-free manipulation is essential.
FAQ
Is this forceps suitable for electron microscopy grid handling?
No—its tip geometry and surface finish are optimized for optical coverslips, not TEM grids. For EM applications, refer to RWD’s dedicated ultra-fine tungsten-tip tweezers (Model F19002 series).
Can it be used with diamond-coated or sapphire coverslips?
Yes—the hardened stainless steel tips (HV ≥ 220) resist wear against abrasive substrates, though prolonged use with sapphire may accelerate tip dulling; periodic inspection is recommended.
Does RWD provide calibration or metrology documentation?
While not a measuring instrument, dimensional verification reports (tip width, angle tolerance ±0.5°, length tolerance ±0.2 mm) are included with bulk orders (>50 units) per ISO/IEC 17025-accredited third-party testing.
What is the recommended cleaning protocol between uses?
Rinse with deionized water, followed by 70% ethanol immersion for 2 minutes; air-dry vertically in a particle-free environment. Avoid ultrasonic cleaning unless validated for your specific lot.
