5mm Micro Insert – Flat Base:

Precision Sample Inserts for Maximum Recovery and Analytical Accuracy

The 5mm Micro Insert with Flat Base is specifically engineered to improve sample recovery and injection accuracy during analytical procedures such as Gas Chromatography (GC) and High-Performance Liquid Chromatography (HPLC). These inserts are placed inside standard chromatography vials to reduce dead volume, allowing even small-volume samples to be efficiently drawn by autosamplers.

Manufactured from high-purity glass, this micro insert ensures chemical compatibility, visibility, and dimensional precision, making it ideal for trace-level analysis and reproducibility in high-throughput laboratory settings. The flat base design is perfect for stable placement within vials and consistent sample pickup by instrument needles.

Key Features and Benefits

  • Optimized for Maximum Sample Recovery
    Minimizes surface area and reduces sample loss by ensuring that even micro-volumes are centrally located and easily accessed by autosampler needles.

  • Flat Base for Consistent Positioning
    Offers excellent vial alignment and ensures consistent sample depth, especially important for high-precision instrumentation.

  • High-Quality Clear Glass Construction
    Provides excellent chemical resistance and visibility for quality control and small-volume handling.

  • Multiple Configurations Available
    Available in various formats including flat bottom, conical bottom, and conical with polyspring, to meet the specific needs of different workflows and vial types.

  • Compatible with Autosamplers
    Designed to fit inside standard 2mL or 1.5mL vials used in HPLC and GC systems, ensuring seamless integration with robotic injection systems.

Applications

  • Gas Chromatography (GC) Analysis
    Serves as a precise link between the injection vial and the GC port, ensuring accurate introduction of liquid or gaseous samples.

  • High-Performance Liquid Chromatography (HPLC) Analysis
    Supports accurate volume control and sampling by enabling better syringe positioning and draw efficiency for small-volume injections.

  • Pharmaceutical, Environmental, and Food Testing
    Widely used in trace compound analysis, ensuring maximum sample usage and minimizing waste.

Whether you’re working with limited sample volumes or demanding analytical standards, the 5mm Flat Base Micro Insert offers an essential enhancement to vial-based sample handling—delivering precision, reliability, and efficiency in every run.
