APEX LABS

LABORATORY VACUUM FILTRATION ASSEMBLIES & OIL-FREE DIAPHRAGM PUMPS

In analytical chemistry, microbiology, and pharmaceutical research, achieving precise, contamination-free separation is everything. Whether you are running routine particulate analysis, mobile phase purification for HPLC, or vacuum-assisted suspension clearing, having a reliable filtration system saves hours of bench time. At Apex Labs, we provide a comprehensive range of premium laboratory vacuum filtration assemblies, dry diaphragm suction pumps, and modular support spares. Engineered using heavy-duty, thermal-shock-resistant Borosilicate 3.3 glass and rugged cast-iron pump chassis, our systems are built to withstand sharp pressure differentials without risking structural implosion.

System Selection Matrix

1. Turnkey Vacuum Filtration Assembly Sets

• Integrated Plug-and-Play Architecture: Combines individual hose barbs, exact tubing profiles, and matching filtration glassware into a pre-tested turnkey set.
• High-Speed Pressure Gradient: Operates at an efficient 15 L/M flow rate, generating constant negative pressure to process heavy viscous solutions up to ten times faster than gravity methods.
• Primary Implementations: Designed for modern HPLC solvent purification, microbial limit testing (MLT), and suspended solids tracking.

2. Standalone Glassware Filtration Assemblies

• Premium Borosilicate 3.3 Geometry: Blends advanced thermal-shock resistance with extra-thick physical walls to completely neutralize unexpected implosion risks under full vacuum.
• High-Capacity Side-Arm Flasks: Ships with standard modular options like our 1000ml Side-Arm Filtration Flask, featuring gas-tight silicone stoppers to ensure zero pressure leakage.
• Flexible System Coupling: Readily routes into pre-existing clinical house vacuum lines or existing benchtop vacuum configurations via standard vacuum tubing.

3. Heavy-Duty Oil-Free Vacuum Pumps

• Zero Volatile Contamination: Dry diaphragm engineering removes the need for pump oils, completely preventing toxic exhaust mist from venting into your cleanroom or back-streaming into filtrate samples.
• Maintenance-Free Bench Lifespan: Eliminates continuous laboratory oil changes, sticky fluid leakages, and regular level checks.
• Rugged Cast-Iron Enclosure: Cast from heavy-duty structural iron to suppress bench vibrations and ensure long-term physical alignment under load.

4. High-Precision Spares & Accessories

• Quick-Release Aluminum Clamps: Locks ground-glass joints together uniformly, securing the membrane filter interface without damaging fragile glass margins.
• Integrated Valve Gauge Manifolds: Features an analog 0-760 mmHg vacuum gauge paired with a 1/4″ adjustable ball valve to micro-regulate pressure thresholds and avoid filter rupture.
