Glass Micro Pipettes<br />
Glass micro pipettes are widely used in<br />
Neuroscience because the point can be pulled<br />
to an incredibly small diameter and maintain<br />
the rigidity to penetrate tissue. Additionally, the<br />
dispense orifice exits from the very tip of the<br />
needle so the wound track can be minimized.<br />
The 1 mm RN compression fitting allows for<br />
quick connection to standard 1 mm capillary<br />
glass. Pull your own needle and attach it to an<br />
RN syringe without wax or glue.<br />
Thin-Layer<br />
Chromatography<br />
(TLC) Needles<br />
TLC needles are custom blunt point needles<br />
made for use with RN <strong>Syringes</strong>. To improve<br />
reproducibility the first 19 mm of the needle<br />
point are coated with PTFE paint. This nonstick<br />
surface is applied to the outside of the tubing and<br />
improves precision by minimizing the chance of<br />
liquid sticking to the outside of the needle.<br />
