1. the chip carrier use tweezers to grasp the sides of the chip as shown in Figure 5 below Slide the chip under the open spring clip so that it sits in the slot at the end of the carrier Slide the chip in until it hits the back edge of the slot mounting fixture chip carrier fos S Figure 5 Mounting a chip onto the chip carrier 6 Before closing the spring clip adjust the position of the chip so that it lines up against either the left or right edge of the slot as you face the open spring clip If you are using ThermoMicroscopes s Microlever chip the chip should line up against the left edge of the slot Ifyou are using Psi s Ultralever chip the chip should line up against the right edge of the slot Note If the chip doesn t line up with the edges of the slot it will be more difficult to align the laser beam at the end of the cantilever These two chip positions are illustrated in Figure 6 below chip carrier chip carrier Cc N i a spring clip il y spring clip Microlever Ultralever Figure 6 Top view of chip carrier shown with Microlever left and Ultralever right chips mounted Installing a Cantilever Chip in the Carrier 5 he Close the spring clip and then lift the chip carrier off the mounting fixture by holding the edges of the carrier CAUTION Be careful n2.
