Automatic Slide Stainer LASS-A40

The frozen section specimen workflow begins with fixing the specimen in cylinder number 1 for 20 seconds, followed by a quick wash in cylinder number 4 for 10 seconds. Next, the specimen undergoes hematoxylin and eosin (HE) staining in jar number 2 for 1 minute and 20 seconds. This is followed by repeated washing steps in tank number 4 and differentiation in tank number 3 to enhance contrast. The process continues with unbluing in tank number 7 and additional washes to prepare the tissue for eosin staining in tank number 8. Subsequently, a series of alcohol gradient washes in tanks 9 through 13 progressively dehydrate the specimen, ending with clearing in xylene tanks 14 and 15. Each step is precisely timed, ranging from a few seconds to over a minute, ensuring thorough staining, differentiation, dehydration, and clearing for optimal microscopic evaluation.

Designed with a bench-top form factor, the Automatic Slide Stainer LASS-A40 fits conveniently in most laboratory settings without occupying excessive space. It has an automatic dyeing rack identification system to prevent program errors and ensure correct protocol execution. An audible program completion alarm notifies operators when staining is finished, enhancing workflow efficiency. The device’s automated water inlet and drainage system minimizes manual intervention, streamlining routine operations.

Our Automatic Slide Stainer LASS-A40 is primarily used in surgical pathology and oncology for rapid intraoperative frozen tissue analysis, aiding timely surgical decisions. It also finds applications in research laboratories for studying frozen tissue samples and in transplant medicine for fast tissue evaluation during organ transplantation procedures. Its fast-staining cycle and accuracy make it valuable wherever frozen section analysis is critical.

Labtron’s Automatic Slide Stainer LASS-A40 features three staining racks, each holding up to 20 slides, allowing simultaneous batch processing of 60 slides. It supports an infinite loop working mode to ensure continuous staining without interruption. It offers a multi-functional 18-step workflow, enabling flexible and programmable staining sequences that can be customized to meet diverse laboratory needs. This makes it ideal for high-throughput pathology labs requiring efficient slide processing.

Automatic Slide Stainer LASS-A40 stainer incorporates priority reagent processing, especially for critical tanks like differentiation and eosin, ensuring optimal reagent timing and usage. The hematoxylin tank includes ultrasonic water bath heating with adjustable temperatures from 0 to 99°C to enhance nuclear staining quality. Additionally, the device features computerized water inlet and drainage systems, reducing waste and maintaining reagent purity. These features combine to deliver reliable and reproducible staining results.
