Automatic immunostainer Leica Bond III: recently incorporate in the lab (end of 2011) this is a fully automated immunostainer that allows the performance of immunostainings in a faster and more efficient way, with the same or even better quality comparing with the traditional method. This immunostainer has capacity for 30 slides per run, which would be finished in approximately 3 hours. Since the incorporation of the lab in the CSF our team has improved the quality of the immunohistochemistries (IHC) performed with this instrument (see NEWS section in our web page). Our staff is also working to optimize immunofluorescence (IF) and In-Situ-Hybridization techniques in this automatic immunostainer.
The Leica Bond III automatic immunostainer can be only used by the HistoPathology Lab members. Please remember that researchers are not allowed to work with this instrument. In case you are interested in performing immunostainings with the Leica Bond III please contact with the HistoPathology Lab staff.
In addition, take into account that to avoid the detachment of the tissues during the process:
Tissue dehydrator LOGOS Microwave Hybrid Tissue Processor, Milestone: tissue sample dehydrator acquired for the lab at the end of 2012. This is the instrument that performs the automatic tissue dehydration, clearing and paraffin infiltration. The LOGOS dehydrator competes in quality, versatility and safety with other dehydrators in the market. It can perform 210 tissue blocks per run, with any kind of tissue up to 6 mm thickness.
The LOGOS tissue dehydrator can be only used by the HistoPathology Lab members. Please remember that researchers are not allowed to work with this instrument. In case you have samples to dehydrate, please see “Tissue dehydration protocol”. Also remember that small mesh cassettes or inserts as sponges or thick paper MUST NOT be used, as they interfere with the appropriate dehydration of the samples.
Tissue embedding console system Tissue-Tek TEC, Sakura: this is the instrument to perform the last step to prepare the solid paraffin blocks with the tissues that have been previously dehydrated and embedded in paraffin with the dehydrator instrument. It consists of two modules, the warm paraffin bath and plates, and the cooling plate, both at the same height. This allows that the specimens can be transferred easily from one side to the other in an ergonomic way. The temperature of the paraffin and plates and the cooling plate is programmed at 62˚C and -5˚C, respectively. The cooling plate has capacity for 60 cassettes.

They can be used for paraffin sectioning, offering a section thickness range from 0.5µm to 100 µm. The sections can then be transferred onto a glass slide and used for a wide variety of staining protocols (basic stainings, immunohistochemistry, in-situ-hybridization or immunofluorescence.
See “Rotatory microtome sectioning protocol” in the PROTOCOLS site in our web page.
Cryostat, MICROM HM 560, Thermo Fisher: microtome to perform frozen or cryoembedded tissues. The structure of the tissues is generally less preserved in a cryosection than in a paraffin section. On the other hand, many antigens which may be degenerated during the paraffin embedding process are kept intact in the frozen tissues, allowing them to be still detectable with an immunostainig. Open top cryostat with ergonomic design for working while standing or sitting. This cryostat offers a section thickness range from 0.5 µm to 100µm. The temperature for the specimen clumper is controlled and ranges from 10°C to -35°C. There is a separate temperature control for the knife carrier down to -35°C. The instrument counts with an automatic approach system (ACA) for quick, precise and safe movement of the specimen towards the blade. We have put a thermometer in the cryostat to check the real temperature in the chamber.
See “Cryostate sectioning protocol” in the PROTOCOLS site in our web page.
Sliding microtome MICROM HM 430, with an adapted fast freezing unit: high precise and ergonomic microtome. The roller-guided knife sledge guidance results in an unachieved smooth running of the knife sledge movement for comfortable and non-tiring working. The section thickness feed that the instrument offers is: from 0 to 10 μm in 1 μm-increments, up to 20 μm in 2 μm-increments and up to 60 μm in 5 μm-increments.

The instrument counts with and adjustable 2x large-field magnifier. Sectioning thickness setting from 1 μm to 999 μm, in 1 μm in increase. To quickly accommodate different application needs, a user can alter the frequency between 0 and 100Hz and select the appropriate amplitude between 0.2 to 1mm in 5mm steps. An adjustable specimen retraction feature protects the specimen from damage during the return stroke of the knife.
See “Vibratome sectioning protocol” in the PROTOCOLS site in our web page.
Microscope Axioskop 2 plus Zeiss with a multi-viewing system of 2 additional positions: this microscope has been designed as a universally applicable microscope for applications in biology and medicine, e.g. for the examination of blood and tissues. It counts with five magnifications:
The multi-viewing system allows three users simultaneously view the same specimen: one person in the middle moving the mechanical stage and the focusing drives, and two more persons on the left and right sides. This system features a realistic impression of working with a microscope for all users. An arrow-shaped light pointer, located inside the eyepiece of the microscope, allows the person in the middle to point out relevant structures or findings.
Ovens (Heraeus Instruments and P-Selecta): these ovens are available to users to dry paraffin sections. They are programmed at 50°C-55°C. In each oven there is a thermometer to check the real temperature inside.
Please, do not modify the temperature of the oven without notifying it to the HistoPathology staff.
Cytospin 4-Shandon Thermo Electron Corporation: ultimate thin layer cell preparation system, to centrifugate cell suspensions onto glass slides. It can process 12 specimens at the same time. Using centrifugal principles, the cytocentrifuge deposits cells onto a clearly defined area of a glass slide and allows for the absorption of the residual fluid into the sample chamber's filter card. Cytocentrifugation also constructively flattens cells for excellent nuclear presentation. During operation, the instrument's spinning action tilts the Shandon Cytofunnels upright and centrifuges cells onto the deposition area of the slide, giving all cell types equal opportunity for presentation. In the Load or Stop position, this unique tilting feature reduces cell loss by preventing residual fluid from coming into contact with the prepared slide.
Shandon Cytofunnels are available for IMP/IMBA/GMI users at the HistoPathology Lab.
Animal blood counter, Scil Vet-abc: the Scil Vet-abc is simple to operate and produces a complete three part differential blood count in only 90 seconds. The machine accepts only EDTA blood, and 12 µl of EDTA whole blood is enough for the measurement. No sample preparation is necessary. The results are automatically printed in the printer next to the instrument. Before putting the blood sample in the machine the smart card should be inserted in the instrument. The smart card provides the device with the settings of the animal species corresponding to the sample. There are four smart cards available in the HistoPathology Lab: mouse, rat and rabbit. The fourth smart card is the control card, to be used with an artificial blood sample to assess the instrument.
The parameters measured by the instrument are: Leucocytes, Erythrocytes, Haemoglobin, Haematocrit, RDW, MCV, MCH, MCHC, MPV, Thrombocytes, Lymphocytes %, Monocytes % and Granulocytes %. In addition, three histograms for Leucocytes, Erythrocytes and Thrombocytes.
