Introduction

Proper sample identification is essential in analytical, pharmaceutical, biotechnology, environmental, and research laboratories. When labeling small containers such as autosampler vials, glass inserts, microcentrifuge tubes, and sample storage vessels, the size of the marker tip can significantly affect legibility and available writing space.

Ultra fine point laboratory markers are specifically designed for applications that require precise, detailed writing on limited surface areas.

Available Ultra Fine Point Sizes

MICROSOLV Ultra Fine Point Laboratory Markers are available in three tip diameters:

• 0.25 mm
• 0.35 mm
• 0.45 mm

These options provide flexibility for different labeling requirements and writing preferences.

Choosing the Right Marker Tip Size

0.25 mm Ultra Fine Point

The 0.25 mm tip produces the smallest line width and is ideal for:

• Glass inserts
• Small autosampler vials
• Micro sample containers
• Detailed coding systems
• Compact labeling areas

This size is particularly useful when maximum writing space is required.

0.35 mm Ultra Fine Point

The 0.35 mm tip offers a balance between fine detail and visibility.

Common applications include:

• Standard autosampler vials
• Laboratory tubes
• Sample storage containers
• General laboratory labeling

Many users find this size provides excellent readability while maintaining fine writing capability.

0.45 mm Ultra Fine Point

The 0.45 mm tip produces a slightly wider line that may improve visibility on larger labels and containers.

This size is commonly used for:

• Routine laboratory labeling
• Larger sample containers
• Bottles and reagent containers
• Applications requiring increased readability

Why Marker Tip Size Matters

Selecting the proper marker tip can help laboratories:

• Improve label legibility
• Maximize available writing space
• Reduce labeling errors
• Enhance sample traceability
• Improve laboratory organization
• Simplify sample identification

The smaller the tip diameter, the greater the ability to write detailed information in confined spaces.

Common Laboratory Applications

Ultra fine point laboratory markers are frequently used for:

• Autosampler vial labeling
• Glass insert identification
• Sample vial coding
• Microcentrifuge tube labeling
• Reagent bottle labeling
• Laboratory inventory management
• Research sample tracking

For applications involving very small containers, finer point diameters can significantly improve labeling efficiency.

Conclusion

Ultra fine point laboratory markers are available in 0.25 mm, 0.35 mm, and 0.45 mm tip diameters. Selecting the appropriate tip size helps improve labeling accuracy, maximize writing space, and maintain clear sample identification throughout laboratory workflows.
