Key Features
Rotational Agitation
Cassettes immersed in reagent rotate at 60 rpm, reversing direction every 60 seconds to promote reagent movement and tissue interaction.
Programmable Shaking
Vertical basket movement can be combined with continuous rotational agitation to create a dynamic helical motion through the reagent.
Centrifuging
The cassette basket rises above the reagent and rotates at 210 rpm, reversing every 15 seconds to help remove residual liquid before transfer.
Up to 240 Cassettes
The standard system accommodates one 120-cassette basket, with selected configurations supporting two baskets and up to 240 cassettes.
10 Programmable Protocols
Up to 10 selectable processing programs can be configured to suit different laboratory workflows.
Power-Failure Protection
Battery-backed safety functions help protect tissue samples during power interruptions and allow processing to resume when power is restored.
Dynamic Tissue Processing Method
The STP-120 combines rotational agitation, vertical movement and centrifuging to increase interaction between tissue samples and processing reagents.
Rotational Agitation
The cassette basket rotates at 60 rpm while immersed in reagent, changing direction every 60 seconds.
This continuous movement is designed to promote reagent penetration and maintain consistent reagent mixing.
3D Dynamic Flow
Vertical shaking of the basket can operate together with rotational agitation, creating a helical movement intended to increase reagent-to-tissue interaction.
Smart Draining by Centrifuging
During centrifuging, the basket rises above the reagent without leaving the vessel and rotates at 210 rpm.
Rotation alternates every 15 seconds to help remove residual liquid and reduce reagent carry-over between stations.
Extended Reagent Use
Reduced reagent carry-over during centrifuging can help limit cross-contamination between stations and support longer reagent use.
Specimen & Operator Safety
The STP-120 incorporates several features designed to protect both tissue specimens and laboratory personnel during routine processing.
Tight-Seal Lids
Tight-seal vessel lids help minimise reagent vapour emissions during processing.
Fume Extraction
STP120-2 and STP120-3 models incorporate a fume extraction system with an active charcoal filter for additional vapour control.
Battery-Backed Specimen Protection
During a power failure, the onboard battery can lower the specimens into reagent to help prevent tissue from drying.
Automatic Restart
Once power is restored, processing automatically resumes from the point at which the interruption occurred.
Smart Failsafe Technology
If a power interruption lasts long enough for paraffin to solidify, the processor can halt the sequence and wait until the paraffin has melted before continuing.
If a processing step runs beyond its programmed time, the display identifies the affected station and shows the duration of the overtime.
The system also supports emergency basket movement when the basket is not trapped in solid paraffin, provides an emergency stop function and allows processing to be paused for urgent sample additions or reloads.
Intuitive User Control
The STP-120 is designed for straightforward operation, with ergonomically arranged controls and an LCD display providing an overview of processing parameters.
Laboratories can configure up to 10 custom processing programs, launch them immediately or use the delayed-start function.
A keypad lock helps prevent accidental changes to programmed settings.
