Leica Biosystems RM2165
Leica Biosystems · Model RM2165
4 Sectioning modes: In the automated mode trimming and sectioning can be done with either a single or continuous stroke. In the manual mode trimming and sectioning uses either the conventional method of completing a full handwheel rotation or the rocking mode. In the rocking mode each change in rotation is electronically detected and automatically converted into an advance of retraction movement. The rocking mode is efficient and quick when trimming small specimens. In addition, it minimizes the risk of developing repetitive motion disorders, which are a typical threat to persons doing routine sectioning every day. All key microtome functions: section and trimming thickness; sectioning speed; coarse and fine specimen advance; sectioning window size; and sectioning mode are controlled by and displayed on the control panel. Programmable horizontal stop function moves the specimen to a preset feed position. Programmable sectioning window automatically reduces the speed of the specimen as it is sectioned then speeds up during the return function to increase productivity without compromising quality. Adjustable specimen stop can be set to upper or lower limit of stroke to facilitate specimen transfer. Section thickness setting from 0.25 to 60um. Trim step settings from 1 to 600um. RS232 port used to download and preset unique sectioning specifications for research projects. Optional low temperature sectioning system (Leica LN 21) is designed to convert the RM 2165 from ambient temperature sectioning to cryosectioning down to -150°C using tungsten carbide, glass or diamond knives.
Key tips
- ·Run QC controls before trusting any repair - an analyzer that passes self-test can still report clinically wrong results.
- ·Rule out a reagent lot change before opening the instrument - it can look exactly like a hardware fault.
- ·Centrifuge rotors have a hard retirement age/cycle limit regardless of visible condition - don't eyeball it.

PM Checklist
Preventive-maintenance tasks typical of this equipment class. Perform to the manufacturer's procedure and your facility's policy - this is general reference, not a schedule for this specific unit.
- ·Daily QC controls run and reviewed
- ·Calibration verification per assay
- ·Routine cleaning and decontamination
- ·Scheduled reagent-path and pump-tubing maintenance
Troubleshooting Approach
A structured starting point derived from the failure modes above. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Sample probe / pipette clog
- Confirm the presentation - typically aspiration error, short sample, carryover - and note the exact alarm or message and the conditions when it occurs.
- Check the most likely cause first: clot/crystal obstruction.
- Isolate the affected subsystem using the manufacturer's functional check or self-test, where one is provided.
- If the fault is confirmed and not a field adjustment, service or replace the sample aspiration probe per the manufacturer's service documentation.
- Return the device to service only after the manufacturer's functional and applicable electrical-safety checks pass.
- Record the findings, any parts used, and the verification results in the maintenance history.
Symptom: Reagent / wash flow fault
- Confirm the presentation - typically clogs, high blank, QC fail - and note the exact alarm or message and the conditions when it occurs.
- Check the most likely cause first: pump tube wear, air in line.
- Isolate the affected subsystem using the manufacturer's functional check or self-test, where one is provided.
- If the fault is confirmed and not a field adjustment, service or replace the peristaltic pump tubing per the manufacturer's service documentation.
- Return the device to service only after the manufacturer's functional and applicable electrical-safety checks pass.
- Record the findings, any parts used, and the verification results in the maintenance history.
