DBS Automatic Puncher – Precision Sample Preparation System

What is a DBS Automatic Puncher?

A DBS automatic puncher is a laboratory instrument used to cut uniform discs from dried blood spot cards for consistent and contamination-free sample preparation.

Quick Answer 

A DBS automatic puncher creates uniform sample discs from dried blood spots using controlled punching, enabling accurate and reproducible laboratory analysis.

Key Takeaways

• Produces consistent discs from Dried Blood Spot samples

• Reduces contamination and manual handling

• Supports high-throughput workflows

• Improves reproducibility in Bioanalysis

• Compatible with clinical and research applications

What Are DBS Automatic Punchers Used For?

These systems are used to:

• Prepare DBS samples for PCR and LC-MS analysis

• Support clinical diagnostics and bioanalytical studies

• Standardize pharmaceutical research workflows

• Enable batch processing in high-throughput labs

• Maintain sample integrity during preparation

How Does a DBS Automatic Puncher Work? (Step-by-Step)

Step 1: Card Placement

DBS card is placed into the punching area.

Step 2: Alignment

The system positions the sample for accurate punching.

Step 3: Punching

A punch head cuts a uniform disc (typically 3–6 mm).

Step 4: Transfer

A punched disc is transferred into a collection plate or tube.

Step 5: Waste Handling

Residual card material is separated into a waste tray.
