LTS-3000B Liquid-based Thin-layer Cytology Slide Processor

Introduction:

The instrument combines density-gradient centrifugation, natural sedimentation and charge capture to complete the automation of specimen process, transfer, sedimentation, staining in one operation. It’s a breakthrough achievement of liquid based cytological techniques.

Features: 

1. Full automation.

Specimen process, transfer, sedimentation and staining are done automatically. No manual operation is needed, which avoid wrong operations and cross contamination. 

2. Efficiency.

1-24 specimens can be processed randomly. It makes specimen process much conveniently and timely. 

Batch processing time is less than 60 minutes. The clearance techniques ensure no cross contamination and occlusion.

3. Charge Capture.

The silicified slide is coated with charges to capture more cells.

4. High detection rate.

The twice density-gradient centrifugation, sedimentation and charge capture techniques improve the collection and detection of lesion cells. The diagnostic material is available with clear background and a thin layer of even cells.

Principles:

1. Density-gradient Centrifugation.

When the specimens are centrifuged in the instrument, the first centrifugation separates the diagnostic material from non-diagnosis debris like cell fragments, impurity, mucus; the second centrifugation enriches diagnostic material.

2.  Sedimentation and Separation.

The process & staining system employs cell diluent for natural sedimentation, since the gravity of lesion cells is higher than that of normal cell. As the settling rate of the former is faster, it will settle on slide in priory and combines with charges on slide. This feature is useful to collect the lesion cells at most extent and improve the positive detection ratio.

 3. Charge Capture.

The special polymer materials are used for slide process, which endows the slide surface with positive charges. The coat can capture cells with negative charges quickly and form the stable bonds; the captured cell quantity reaches to 5,000 - 50,000 per slide in case of white slide and cells dropping. 

4. Automated Staining.

The process & staining system performs full automated dripping staining with mechanical arm; each waste liquid from staining is discharged on time; after each staining is finished the mechanical arm flushes immediately in case of the cross contamination, the Pap and HE staining can be done quickly.
