其他气相色谱（GC）进样针

• Borosilicate Glass - inert to GC solvents and organics
• Stainless Steel - inert and non-reactive
• Industry Standard Size - consistent syringe fit
• Metal Flange - protect glass barrel from breakage
• Permanent Scale Markings - solvents won’t wash off the markings
• 0.5 ?L to 1 mL Volumes - wide range for ideal sample take up and delivery
• Plunger Protection - prevents plunger bending incidences
• White Scale Backing - easy-to-read improves reproducibility
