When preparing to securely relocate your Beckman LS6500, it's essential to dismantle the lead assembly (Beckman PN. 500670) — a set of eight lead segments — from the detector assembly first. Nestled within the upper compartment of the LS6500, the lead assembly contributes to a top-heavy configuration, which could make the instrument unstable during a move. Carefully removing these components is a critical measure to protect the delicate photomultiplier tubes (PMTs) that are integral to the detector assembly.
