The Hamilton 80393 was straightforward to install in the autosampler. I followed the standard operating procedure for syringe replacement, and the autosampler recognized the new syringe immediately. No adjustments or calibrations were needed, which saved considerable time and effort.

There were no surprises or issues encountered during the initial use. The syringe performed exactly as expected, providing precise and reliable injections. This performance significantly improved the consistency of our GC-MS analyses.

Extended Use & Reliability

After several months of continuous use, the Hamilton 80393 has maintained its excellent performance. The syringe continues to deliver accurate and reproducible injections without any noticeable degradation in performance. It has proven to be a highly reliable component of our GC-MS system.

The syringe shows no signs of wear or damage, despite being subjected to numerous injection cycles. The cemented needle remains securely attached to the syringe barrel, and the plunger moves smoothly without any binding or sticking. The durable construction of the Hamilton 80393 ensures its longevity and reliability.

Cleaning and maintenance are simple. I regularly flush the syringe with appropriate solvents after each batch of samples. This prevents carryover and maintains the syringe’s optimal performance.

In comparison to previous experiences with generic syringes, the Hamilton 80393 outperforms them significantly in terms of accuracy, reliability, and durability. The improved consistency of the analytical results has reduced the need for repeat analyses. This has resulted in a substantial increase in laboratory efficiency.

Breaking Down the Features of Hamilton Syringes for Agilent Technologies 7673A Autosampler, Hamilton 80393 Microliter Cemented Needle Syringes

Specifications

The Hamilton 80393 Microliter Cemented Needle Syringe boasts the following specifications:

• Volume: 10 µL: Ideal for small volume injections commonly used in GC-MS and HPLC analyses.
• Needle Gauge: 23S/26S: A combination gauge offering durability with the 23-gauge base and improved performance with the 26-gauge tip for split/splitless and on-column injections.
• Needle Type: Cemented: The needle is permanently attached to the syringe barrel, minimizing dead volume and preventing leaks.
• Hamilton No.: 80393: This number is the unique identifier for the Hamilton product.
• Compatibility: Agilent Technologies 7673A Autosampler: Designed specifically for use with this particular autosampler model.

These specifications are critical for ensuring precise and reliable injections. The small volume capacity allows for accurate delivery of small sample aliquots. The cemented needle design minimizes sample loss and carryover. The compatibility with the Agilent 7673A autosampler guarantees seamless integration and optimal performance.

Performance & Functionality

The Hamilton 80393 excels in its primary function: delivering accurate and consistent injections for automated GC-MS analysis. Its design minimizes dead volume and prevents leaks, ensuring that the entire sample is delivered to the analytical instrument.
