Sampling 2 or 3 μΙ. is no laughing matter. Are you injecting 2 or 3 ul samples, or even less, using a 10 μΙ syringe and experiencing traditional difficulties of bending plungers and fixed needles? Not to mention loss of accuracy due to doubtful short-scale readings. The SGE 5 ul syringe with removable needle (RN) and guided plunger (GP) takes care of that. The illustrated 5A-RN-GP syringe has an extended barrel and reinforced plunger plus a leak-free removable needle which combine to give the syringe strength and durability for a long service life. Injection is smooth and accurate. Also available in 10,15 and 25 μ I versions. And that is really something to smile about. Please write for our "Precision Microlitre Syringe" catalogue.
