96 Well Filter Plate

Reliable High-Throughput Filtration for Consistent Sample Preparation

Not All 96 Well Plates Deliver Consistent Filtration

In high-throughput workflows, filtration is not just about speed — it directly affects data reproducibility, recovery rate, and downstream analysis accuracy.

Uneven flow rates, membrane inconsistency, or poor chemical compatibility can lead to:

• Variable results between wells
• Sample loss in protein or biological workflows
• Contamination or interference in HPLC / LC-MS analysis

Hawach 96 well filter plates are designed to provide uniform filtration performance across all wells, enabling reproducible results at scale.

Product Overview

Hawach 96 well filter plates are microplate-format filtration devices with integrated membranes in each well, allowing simultaneous processing of up to 96 samples via vacuum or centrifugation.

They are widely used in molecular biology, analytical chemistry, and drug discovery workflows, where parallel processing and consistency are critical.

Key Features

• 96-well (8 × 12) format for parallel processing
• Compatible with vacuum manifolds and centrifugation
• Multiple membrane materials for different sample types
• ANSI/SBS standard footprint for automation systems
• High chemical resistance polypropylene structure

Key Specifications

Membrane Selection Guide

Use-Case Based Selection

Choose the right configuration based on your workflow:

For LC-MS / HPLC sample prep
– 0.22 µm PES
– Cleaner baseline, reduced particulate interference

For protein precipitation workflows
– PES (best recovery) or Nylon (cost-effective option)

For high-throughput screening (HTS)
– 1.0 mL plates
– Balanced volume and filtration speed

For organic solvent filtration
– PP membrane
– Stable under aggressive chemical conditions

Typical Applications

• Sample preparation before HPLC / LC-MS
• DNA / RNA clarification and purification
• Protein precipitation and biological sample cleanup
• High-throughput screening (HTS) and assay workflows
• Removal of particulates from analytical samples

Why Hawach 96 Well Filter Plates Perform More Consistently

Uniform membrane integration across all wells
– minimizes well-to-well variability

Controlled flow rate design
– reduces clogging and uneven filtration

Wide chemical compatibility (aqueous + organic)
– supports multiple workflows with one platform

Stable plate structure under vacuum and centrifugation
– prevents deformation, leakage, and inconsistent flow

Recommended Operating Parameters
