The full scale capacity of this syringe is one microliter
It's hard to imagine, when you look at this syringe, that it's not a normal syringe. Your sample never reaches the glass barrel. The barrel is used simply as a volume indicator. It's all in the needle The total capacity of the syringe is contained in the needle. A tiny tungsten wire plunger travels to the tip of the needle, discharging the complete sample.
It's available in three capacities: 1.0 μΐ, 2.0 μΐ, and 5.0 μΐ. With any degree of skill samples can be repeatably injected to ± 1 % . You can use Hamilton's plunger guide or Chaney Adaptor to make
injections easier and strengthen the plunger against bending.
There's a Teflon seal in the hub that can be finger tightened to compensate for wear and to prevent leakage. You simply tighten the knurled hub to make the adjustment for a leak-tight seal. Tested for accuracy Every 7000 Series syringe is tested for accuracy by injecting a series of samples into a gas chromatograph. When you purchase a Hamilton 7000 syringe, you have our guarantee that it will deliver the capacity with reproducibility to ± 1 % . CIRCLE 9 4 O N READER SERVICE CARD

The 7000s come with a 90° needle point, which has proven successful in providing longer septum life and in reducing the likelihood of septum traces being injected. If you need to inject samples smaller than 1.0 μΐ, this is your syringe. Five models, three capacities: 1.0 μΐ, 2.0 μΐ, and 5.0 μΐ, selling for $35.00. They're available from authorized dealers or direct from the factory. For more information and literature, write to John Nadolny, Hamilton Company, Post Office Box 10030 Reno, Nevada 89510.
