FAQ Leica ST5020
ST5020
Can the Autostainer and Multistainer Workstations also be operated with the deep load container in the Coverslipper?
Yes, since August 2006, both workstations can be operated with the deep load container. Thus, the covering on the slides will be improved and problems during coverslipping, like the forming of bubbles, will be eliminated.
In order to ensure the proper function of the deep load container in the CV/ST combinations, the workstations have to be modified before using the container. A catch plate is already installed and the spacer has to be modified to ensure correct function.
Please contact your local Leica service representative for further details. Without prior retrofitting of the instruments, the use of the deep load container will lead to substantial functional problems.
When does the filling process of the water stations start and how long does it take until the stations are filled?
The filling process starts 40 seconds before the rack is picked up by the transfer arm and it takes approximately 20 seconds to fill the water stations.
How many racks can be stained at the same time?
Depending on the staining protocol 4 to 9 racks can be stained simultaneously.
What can be done if there is too much carryover?
Lower the lift speed (1 = less carryover; 9 = more carryover). Place the staining solutions next to water stations. Avoid long distances between stations.
What is the recommended slide drying time?
After a warm up period of approximately 5 minutes it takes 15 minutes to dry slides at 70 °C.
How often does the activated carbon filter need to be replaced?
Every 3 months.
Why is the gripper dropping racks?
The handles of the stations are located on the wrong (left) side.
Why is the rack not picked-up from the load station?
- SUPERVISOR mode is still activated.
- The next station is already occupied.
- There is no clip on the rack.
- The rack is inserted with the clip to the rear side.
- Programs are not compatible.
What is the meaning of the red bar in the station button on the display?
The Reagent Management System (RMS) is activated. The longer the red bar the closer the time the reagent has to be changed.
What are the possible reasons for a program not starting?
One step in the program has no defined station-time. The reagent in the program-step does not correspond with the station or vice versa. The CV5030 is not switched on.
Why is a rack that is programed to be coverslipped placed into the exit station instead?
The CV5030 is turned off during the staining process. The cables connecting the ST5020/CV5030 workstation have become loose.
The stained slides are available in the last station of the ST5020. Why does the transfer arm not transport the rack to the Coverslipper although it’s programed to do so?
The CV5030 is busy or needs attention, e.g. there’s still a rack in the bath or the transfer station is occupied with three racks.
Is there any limitation on programming exact steps?
Except for the last station in a staining protocol, every step can be programmed as an exact step. The last station always needs an interaction, either from the user or the workstation.
How many clip colors are available?
Nine different colors are available:
White – order number 1407533632
Yellow – order number 1407533633
Light blue – order number 1407533634
