The Vacuum Filtration System is an essential piece of laboratory equipment used for the rapid and efficient separation of solid particles from a liquid medium. By applying negative pressure (a vacuum) beneath the filter medium, the liquid (filtrate) is forcefully pulled through, leaving the desired solid precipitate (retentate) on the filter surface.
This system is widely used in chemical synthesis and materials processing to isolate and purify final products, making it a cornerstone for efficient solid-phase extraction and cleanup in high-throughput research and Quality Control laboratories.
Primary Applications
Materials Chemistry & Functional Surfaces:
Precipitate Isolation: Separating solid crystalline or amorphous products from synthesis solutions.
Washing and Purification: Rinsing solid materials (e.g., nanoparticles, pigments) to remove residual solvents or impurities, ensuring high purity for downstream applications.
Analytical Chemistry / Quality Control:
Sample Preparation: Clarifying or purifying liquid samples (e.g., solvents, mobile phases) before injection into analytical instruments like HPLC (High-Performance Liquid Chromatography) to protect sensitive columns and ensure accurate results.
Chemical and Industrial Processing:
Large-Volume Batch Filtering: Used for large-scale benchtop filtration of chemicals, ensuring a faster turnaround time for intermediate or final products.
System Configuration and Accessories
Filter Holders: Choose from glass filter funnels for compatibility with corrosive solvents or stainless steel holders for high-pressure or high-temperature applications.
Vacuum Pump: We offer complementary corrosion-resistant diaphragm vacuum pumps suitable for chemical vapors, ensuring system longevity and stable vacuum pressure.
Safety Trap: Crucial component to protect the vacuum pump from accidentally sucking back filtrate or solvent vapors.
