Cole Parmer Flowmeter Kit with Milwaukee Valve 8 SCFH / 3.5 L/min Lot of 4

Cole-Parmer Variable Area Flowmeter Kit – 8 SCFH / 3.5 L/min Capacity, Built-In Manual Flow Control Valve, Compact Acrylic Housing (MPN: 34500-30 Kit Series)

The Cole-Parmer 34500-30 Flowmeter Kit is an instrument-grade variable area flowmeter precision-engineered to monitor, measure, and control liquid or gas flow rates in critical laboratory workflows and light industrial applications. Calibrated for standard capacity limits up to 8 SCFH (Standard Cubic Feet per Hour) or an equivalent 3.5 L/min (Liters per Minute), this kit features an ultra-clear, shatterproof acrylic block housing that ensures crisp, unobstructed visualization of the internal indicating float. Outfitted with heavy-duty metal connections and paired alongside a high-precision Milwaukee flow-control valve, this unified fluidic panel allows laboratory technicians to fine-tune inline fluid velocities while completely eliminating localized micro-leakage and systemic flow-path turbulence.

Technical Performance and Design

• Optically Clear Acrylic Block Matrix: Injection-molded from a solid, shatter-resistant acrylic block. The highly polished interior bore minimizes visual distortion, featuring high-contrast dual graduation scales for error-free monitoring of the internal tracking float.

• Integrated Fluid Control Valve: Equipped with a rugged, built-in manual metering needle valve system. This mechanical configuration allows operators to implement precise linear adjustments to gas line pressures, securing repeatable fluid delivery factors.

• Concentric Inline Stability: Engineered with robust brass or stainless steel internal fittings that absorb piping torque. The durable wetted material profile prevents thread cross-stripping, resisting system degradation when handling standard laboratory gases and utility water lines.

• Versatile Panel-Mount Architecture: Designed for straightforward through-panel installation or standalone rigid pipeline attachment. The compact 4-inch footprint allows it to adapt into tight space-constrained gas blending panels and analyzer cabinets.

Key Benefits and Applications

• Laboratory Gas Purging Manifolds: The ideal inline tracking component for managing inert gas purging lines (such as Nitrogen or Argon) inside environmental chambers, gloveboxes, and reaction vessels.

• Chemical Blending Line Monitoring: Widely utilized across pilot plants and formulation test benches to verify constant delivery ratios of low-viscosity liquid reagents and process water feeds.

• Filtration Loading Monitoring: Provides immediate visual confirmation of flow drops across standard inline cartridge filters, helping technicians log routine membrane replacement cycles.

• Simplified Maintenance Flushes: The streamlined variable area interior allows for straightforward backflushing and block cleaning routines without disturbing the pre-plumbed backing panel frame.
