for histology laboratorieslaboratoryfor slide staining

Overview
Leica ST4020 is a compact linear stainer designed for in vitro diagnostic laboratories. It combines software-programmable protocols and advanced automation to enable unattended runs and rapid handling of urgent samples while supporting consistent staining performance.

Product features

• Low reagent volumes to reduce waste and lower reagent costs; optional agitation and running-water stations for protocol flexibility.
• Supports 1 to 4 slides per run with continuous loading and audible end-of-protocol notification to accelerate turnaround.
• High throughput capability: more than 400 slides per hour (depending on protocol and configuration).
• Compact footprint suitable for installation near a cryostat to process urgent frozen sections.
• Flexible programming: variable protocol start position, programmable station time from 2 to 300 seconds, up to three rinse stations, and optional agitation (0–3 dips).

Recommended applications

• Skin specimens including Mohs surgery samples.
• Frozen sections and intraoperative samples.
• Fine needle aspirates.
• Routine biopsies requiring rapid turnaround.
