13. Appendix D: Mechanical Grip Usage

Installing Grips

In addition to BioRakes, the BioTester can optionally be equipped with mechanical grips for
sample attachment.
The mechanical grips can be equipped with three different springs of varying stiffness to exert
different gripping forces. These springs are provided with the grips and may be switched at any
time using the provided hook tool.
The light, medium and heavy springs will exert 1.5N, 6N, and 15N of gripping force respectively.
System Alert
Select the appropriate grip spring for the load cell in use. Using a grip with the stiffest
spring in combination with a low capacity load cell (0.5-2.5N) may produce high forces
when mounting a sample. Load cells can be damaged by large off-axis or bending
forces.
The grips can be attached using the following steps:
1. Slide the grips onto the goosenecks as pictured below.
2. Tighten the locking fastener to hold the grips in place on the gooseneck. Do not over-
tighten the locking fastener as this may push the tip of the grip out of alignment.
