Common Agilent Autosamplers and Vial Compatibility
Most Agilent LC autosamplers are designed to use standard 12 × 32 mm autosampler vials, including systems such as:
- Agilent 1100 Series HPLC System
- Agilent 1200 Series HPLC System
- Agilent 1260 Infinity LC System
- Agilent 1290 Infinity II LC System
These autosamplers are optimized for vial dimensions that ensure:
- Proper needle entry
- Consistent injection depth
- Reliable tray indexing
- Reduced risk of missed injections
Recommended Vial Specifications
For most Agilent autosamplers, the following vial configuration provides the best compatibility and performance.
Vial Format
- 12 × 32 mm autosampler vial
Capacity
- 1.5 mL or 2.0 mL
- Limited-volume inserts or fused inserts can be used for small sample quantities
- Helps ensure the autosampler needle consistently reaches the sample while minimizing sample loss
Neck Finish
- 9 mm screw thread
- 11 mm snap top vials
- 11 mm crimp top vials
Material
- Type I borosilicate glass
- Polypropylene
Closure
- PTFE/silicone septa with slit
This configuration is widely used across LC laboratories because it balances instrument compatibility, sealing performance, and ease of use during high-throughput workflows. At Chrom Tech, we recommend slit septa for Agilent HPLC systems to help prevent autosampler errors and minimize downtime.
Agilent Autosampler Considerations
Based on Chrom Tech’s experience supporting Agilent LC systems, several factors can influence autosampler vial performance.
1. Septa Quality Matters
Autosamplers performing high injection counts benefit from septa that resist coring and maintain a proper seal. Pre-slit septa improve injection reliability and help reduce autosampler errors.
2. Consistent Vial Dimensions Are Important
Variability in vial height or opening diameter can affect needle alignment. High-quality vials with tight dimensional tolerances help maintain reliable injection performance.
3. UHPLC Systems Are More Sensitive
High-performance systems such as the Agilent 1290 Infinity II LC System operate at higher pressures and faster injection speeds. These systems benefit from precision-manufactured vials that maintain consistent geometry and sealing performance.
Quick Compatibility Summary
Most Agilent LC autosamplers are compatible with:
- 12 × 32 mm autosampler vials
- 9 mm screw thread vials or 11 mm snap top vials
- 1.5 mL or 2.0 mL capacity
- Vials with inserts for small sample volumes
Using these standard configurations ensures proper autosampler operation and reliable chromatographic results.
