SGE 000506 Plunger-in-Needle 1BR-7BV NanoVolume 1µL Syringes have the ability to inject with high precision and accuracy. They are perfect for nanovolume capillary chromatography injection. The sample is only drawn up into the needle, not the syringe barrel. When the plunger is depressed, the sample is completely dispensed by the NanoVolume plunger that extends right to the tip of the needle. Note: The plungers and needles are matched sets and must be replaced as a set.
