An arrangement used in connection with the withdrawal of cerebral spinal fluid (CSF) from a spinal column comprising a hub having a chamber therein for receiving CSF; a cannula being coupled to the hub to permit communication of CSF with the hub, the cannula having a first end securable within the hub and a second end dimensioned to permit withdrawal of CSF from a spinal column; wherein the hub includes walls forming an opening therebetween, and wherein a arcuately shaped magnifier is disposed within the opening, wherein the magnifier includes edges that extend below the top surface of the walls of the hub such that at least a portion of the curved outer surface of the magnifier extends below the top surface of the walls of the hub; whereby the magnifier can be positioned in close proximity to the chamber to improve magnification of the CSF as it enters the chamber and decrease the recognition time from when the CSF first enters the chamber of the hub. A flashback indicator and a hub for use in a flashback arrangement are also provided.
