GC Instrument Gas-tight Syringe, Fixed Needle
Get durability, clarity and accuracy in gas chromatography (GC) sample introduction for confidence in analytical results, time-after-time. Thermo Scientific Fixed-Needle, Gas-Tight Syringes offer an affixed needle and a plunger that creates a tight seal with the barrel. Choose from a variety of sizes, types and gas chromatography autosampler compatibilities. They are available in standard industry size with black easy-to-read and solvent-resistant markings.
Durability
The enhanced design of the syringes delivers:
- Improved solvent resistance
- Greater temperature range
- Longer lifetime and improved cycle life
Clarity
Syringes are provided with a clear, easy-to-read black scale, which aids in consistent delivery of samples for manual syringes and easy identification of installed autosampler syringes.
Accuracy
The enhanced design of the syringe has eliminated areas where the sample can become trapped and potentially cause carryover:
- Closer fit between the plunger tip and PTFE insert at the zero position
- Tighter fit between PTFE insert and glass barrel
- Improved fixed needle attachment
In addition, the reduction in adhesive from the fluid path enhances durability and reduces the risk of sample interaction with the adhesive.
