Laboratory Filter Press
Precision Lab Filter Press | Compact Filtration Solutions for Research & Testing
Compact, high-accuracy laboratory filter press for material testing, pharmaceuticals, and chemical research. Adjustable pressure, corrosion-resistant materials, and data logging.
The Lab Filter Press features a compact and robust design, specifically tailored for laboratory use. It consists of a series of small filter plates covered with filter cloths, forming chambers for slurry filtration. The plates are clamped together using a manual or hydraulic system, creating a sealed environment for the filtration process.
The Loway Laboratory Filter Press is engineered for precision solid-liquid separation in research and quality control environments. Ideal for small-batch testing, formulation development, and process optimization, this bench-scale system replicates industrial conditions with laboratory-grade accuracy.
Key Features:
✅Compact design ideal for laboratory environments

Working Principle
Filter presses operate on the principle of pressure filtration. The process involves:
- Feeding slurry into the chambers formed between filter plates
- Applying pressure to force liquid through filter cloths or membranes
- Retaining solids as filter cakes between the plates
- Releasing pressure and separating plates to remove the cake
Filtration Methods
- Chamber filtration: Utilizes recessed plates to form chambers
- Membrane filtration: Uses flexible membranes for additional compression
- Plate and frame: Alternates frames and plates for enhanced filtration

Common Questions
Have More Questions? Our technical team is ready to provide detailed, personalized guidance.
Q1: How does a lab filter press differ from industrial models?
Lab units are smaller, with lower throughput but higher precision for testing. They often include advanced controls for data collection.
Q2: Can I customize plate size or materials?
Yes. We offer plates in stainless steel, polypropylene, or PTFE-coated options, with sizes from 100x100mm to 300x300mm.
Q3: What’s the typical filtration cycle time?
Ranges from 20 minutes to 2 hours, depending on slurry viscosity and desired cake dryness.
Q4: Can a lab filter press handle high-viscosity liquids?
Yes, but high-viscosity slurries may require higher operating pressures and longer filtration cycles. Pre-treatment with flocculants or heating may improve filtration efficiency.
Q5: What is the difference between a lab filter press and industrial models?
Lab filter presses are smaller, often with manual operation, designed for processing small volumes (0.5-20L). Industrial models handle larger volumes (hundreds or thousands of liters) with higher automation and throughput.
Q6: What filter media is best for fine particle separation?
For particles below 10 microns, multi-layer filter cloths or membranes with 1-5 micron ratings are recommended. Consider depth filtration media for the finest particles.
Q7: How can I increase filtration speed?
Optimize your process by:
- Using filter aids like diatomaceous earth
- Selecting appropriate filter cloth porosity
- Adjusting operating pressure
- Pre-treating slurry with coagulants
- Maintaining proper slurry temperature
