Frequently Asked Questions

Approximately how many cassettes can be processed in one basket?

The recommended number for one basket is 80 cassettes. But when stacking, the maximum capacity is 100 cassettes. However, to ensure complete infiltration, no cassette may lie on top of the stacked cassettes, so the filling height has to be reduced.

How many programs are adjustable?

Nine different programs can be adjusted. Programs 6 to 9 are preset by the manufacturer with standard values, however they can be altered.

Is it possible to leave out one station in a program?

A station will be skipped if the infiltration time is set to 0 h 00.

What has to be considered when retrofitting a TP1020 with a second basket holder?

The standard delivery for this upgrade includes 1 basket holder, 1 paraffin station and 1 station holder for the paraffin station. The second tissue basket has to be ordered separately, so you can specify the standard or three level type.
When installing the third paraffin bath instead of the reagent station, make sure the instrument setup in the configuration menu is changed accordingly.

What has to be considered when programming a two-basket program?

With two-basket programs, the infiltration time must be the same for all stations. This is because both baskets must move together. When choosing the infiltration time, remember that basket 1 will skip the first fixation station and basket 2 will stop before last paraffin station.

Can chloroform be used in the TP1020?

It is possible to use chloroform in the TP1020. However, when using chloroform a special wax bath must be used.

Is it possible to retrofit a TP1020 basic version with vacuum function and fume control system?

A TP1020 cannot be upgraded with vacuum function and/or fume control system.
So please carefully consider your requirements before selecting an instrument.
We offer four different versions:
Basic instrument; Basic instrument with vacuum function; Basic instrument with fume control system;
Basic Instrument with vacuum function and fume control system.

What’s the meaning of the ‘V’- button on the control panel of a Leica TP1020 without the vacuum function?

On every version of the Leica TP1020 the control panel is identical. However, the ‘V’ - button is not functional on instruments without vacuum function. 

Why must two activated carbon filters be inserted in the Leica TP1020?

One filter is for formalin, the other one for all the solvents.

How often does the activated carbon filter need to be changed?

Every 3 months. Please note there is a potential fire risk from a filter which is saturated with solvents when you don’t change them at regular intervals!

What is the advantage of using the fume outlet tube instead of the activated carbon filters?

The fume outlet tube provides a better exhaust and there are no ongoing filter replacement costs.

Can the reagent containers be cleaned in the dishwasher?

The glass containers are dishwasher proof up to 80 °C, however the carriers are not. Please remove the carriers before inserting the containers in the dishwasher. The aluminum containers are not dishwasher proof.
