Buying advice

When choosing a gas-tight syringe, consider the volume range needed, chemical compatibility (especially with solvents), and the type of plunger seal (PTFE is common for inertness). For high-precision analytical work (e.g., GC), a syringe with a reinforced plunger and smooth action is preferred. For budget-conscious buyers, the Exmire offers good value. Ensure the syringe fits your instrument if using an autosampler. Avoid overtightening the plunger to prevent bending.
