Beckman Biomek Tips: Conductive vs. Non-Conductive – Which One Do You Need?

Beckman Coulter Biomek workstations (i5, i7, NX, FX series) are trusted platforms for high-throughput automation in genomics, proteomics, and drug discovery. Selecting the right automation tips—conductive or non-conductive—directly impacts assay performance, liquid level detection accuracy, and overall workflow efficiency.

With options including conductive tips for liquid level detection, filtered tips for contamination control, and standard tips for routine workflows, how do you know which one is right for your application?

This guide will help you understand the differences and make an informed decision.

🔬 1. Understanding Beckman Biomek Tip Types

✅ Conductive Tips

Conductive tips are manufactured from carbon-filled polypropylene, providing static dissipative properties that enable capacitive liquid level detection (LLD) in Beckman systems. This is critical for assays requiring precise aspiration from variable liquid heights.

When to use conductive tips:

• Liquid level detection (LLD) applications – Any assay where the system needs to detect the liquid surface
• Variable volume workflows – When sample volumes vary between wells
• Low-volume pipetting – Improves accuracy for small volumes
• Automated cherry picking – When tips must detect different liquid heights

Advantages:

• Enables capacitive liquid level detection
• Prevents static charge buildup
• Essential for many automated protocols
• Available in 50μl, 250μl, and 1025μl volumes

Disadvantages:

• Higher cost than standard tips
• Not required for all applications

✅ Filtered Tips

Filtered tips contain an aerosol barrier that prevents contamination of the pipetting head and cross-contamination between samples.

When to use filtered tips:

• PCR setup – Prevents aerosol cross-contamination of nucleic acids
• Infectious or pathogenic samples – Protects the instrument and operator
• Radioactive or toxic materials – Adds an extra layer of safety
• Precious or limited samples – Prevents sample loss due to contamination

Advantages:

• Prevents carryover contamination
• Protects the pipetting head from aerosols
• Ideal for sensitive molecular biology applications

Disadvantages:

• Higher cost than non-filtered tips
• Slightly increased pipetting force required

✅ Standard (Non-Conductive, Non-Filtered) Tips

Standard tips are the economical choice for routine liquid handling where LLD and aerosol protection are not required.

When to use standard tips:

• Routine buffer and reagent dispensing
• High-volume applications – Where cost is a primary concern
• Assays without LLD requirements
• Method development and testing

Advantages:

• Most economical option
• Suitable for >70% of automation applications
• Available in all standard volumes

Disadvantages:

• No liquid level detection capability
• No aerosol barrier

📏 2. Volume Ranges and Applications

Volume	Tip Type Options	Typical Applications
50μl	Conductive, Filtered, Standard	PCR setup, small volume dispensing, reagent additions
250μl	Conductive, Filtered, Standard	General purpose, most common volume for automation
1025μl	Conductive, Filtered, Standard	Larger volume transfers, buffer dispensing, media preparation

📦 3. Packaging Options

✅ Racked (96 tips/rack)

• Ready-to-use, pre-racked tips
• Compatible with Beckman systems without additional handling
• Standard packaging: 50 racks/case
• Ideal for laboratories with moderate to high throughput

✅ Bulk (Bagged) Tips

• Economical packaging for high-volume users
• Requires manual loading into empty racks
• Reduces plastic waste and cost per tip
• Ideal for laboratories with very high throughput

🧪 4. Quality and Certification

Infectious sample handling	Filtered	250μl or 1025μl	Racked
Routine buffer dispensing	Standard	1025μl	Bulk
High-throughput screening	Conductive	250μl	Bulk
Method development	Standard	Various	Racked (small quantities)

⚠️ Important Compatibility Note

These tips are third-party manufactured and designed to be compatible with Beckman Coulter liquid handling systems. They are not original equipment, not affiliated with or endorsed by Beckman Coulter, Inc. For research use only (RUO). Not for clinical or diagnostic use.

❌ Common Mistakes When Choosing Beckman Biomek Tips

• Using standard tips for LLD applications – Liquid level detection will not work, causing crashes or inaccurate aspiration.
• Using non-filtered tips for PCR – Risk of cross-contamination and false results.
• Choosing the wrong volume – Using 1025μl tips for 10μl transfers reduces accuracy.
• Mixing tip types in critical assays – Inconsistent performance may affect results.
• Assuming all third-party tips are the same – Quality varies; choose certified tips from reliable suppliers.
