Precise alignment for clean, repeatable cuts V-Guide alignment system with ±0.1 mm positioning accuracy produces smooth fracture lines on tubing from 1–60 mm diameter. Prevents jagged edges on laboratory glassware and fluid-transfer components. Durable, high-performance blade Circular tungsten carbide blade rated at 62 HRC hardness and proven for 500+ cutting cycles on borosilicate glass. Maintains a sharp edge longer than standard steel cutters for demanding lab and pharmaceutical use. Ergonomic safety design Ratchet mechanism reduces required hand force by approximately 60%, lowering user fatigue for repeated cuts. Integrated blade guard minimizes the risk of accidental cuts during demonstrations, classroom work, and routine lab tasks. Multi-material compatibility Designed to cut borosilicate and soda-lime glass, polycarbonate chromatography columns, acrylic rods, and other common lab plastics without introducing micro-cracks. Suitable for precision work on scientific instruments and fluid systems. Key specifications Cutting range: 1–60 mm tubing/rod diameter Positioning accuracy: ±0.1 mm (V-Guide alignment) Blade: circular tungsten carbide, ~62 HRC, rated for 500+ cycles Safety: ratchet mechanism and blade guard How this solves common problems Eliminates jagged or uneven edges that cause leaks, poor seals, or assembly problems in lab glassware and fluid-transfer systems. Reduces rework and scrap by delivering consistent positioning and repeatable fracture lines. Lowers hand strain and improves operator safety during frequent or precision cutting tasks. Practical use scenarios Laboratory glass preparation: cutting borosilicate tubing to exact lengths for condensers, adapters, and custom glass apparatus with smooth ends that reduce sealing issues. Instrument repair and maintenance: trimming acrylic rods or polycarbonate components for scientific instrument rebuilds or retrofit work without causing micro-cracks. Aquarium and CO2 systems: cutting acrylic tubing and rods for CO2 diffusers and custom fittings where clean edges and reliable seals matter. What stands out Laboratory-grade alignment accuracy (±0.1 mm) combined with a long-lasting tungsten carbide blade gives repeatable, high-quality cuts across glass and plastics. Ergonomic ratchet and guarded blade reduce fatigue and injury risk, making the tool practical for both occasional and high-volume users. Compatibility and care Use on borosilicate glass, soda-lime glass, polycarbonate, and acrylic. Follow standard lab safety procedures when cutting glass and plastics, and inspect the blade regularly to maintain cutting quality.
