A worldwide unique technique
Tissue processing is a technique that uses alcohols to remove water from tissues and replace it with a medium that allows sectioning of tissue. Several methods are used to achieve this. Myr Spin Tissue Processor STP 120 fulfills it in a patented and unique technique that combines several movements for the tissue to achieve perfect infiltration results. This is possible thanks to the world’s best spin processing method.
Spin Tissue Processor
ROTATIONAL AGITATION. The basket with the cassettes is immersed into the reagent vessel. In this position, the basket turns at 60 rpm and changes the rotational direction every 60 seconds. The rotational agitation achieves a perfect infiltration of tissue, an homogeneous mixture of the reagents and a reduction of processing time. To get better results, the user can start optionally a shaking process.
SHAKING. This movement can be optionally activated on the control panel and allows the basket to perform an up-down movement inside the vessel that combined with the rotational agitation fulfills an helicoidal movement that increases infiltration quality at a high degree of precision. At the end of this process, baskets start centrifuging.
CENTRIFUGING. This function is activated as soon as the infiltration time comes to an end. The basket rises above the reagent’s level but rests inside the vessel. For a period of 60 seconds, it starts whirling at 210 rpm and changes the rotational direction every 15 seconds. This process allows the tissue to be optimally drained and avoids carry-over of reagents from one vessel to another.
Ergonomic control panel
The buttons of the control panel are arranged ergonomically for easy handling. The LCD display shows all the parameters throughout the process, such as program number, vessel, remaining time, start time, start delay, total duration of the program, rotational agitation and shaking, basket’s centrifuging, temperature of paraffin baths, date and time.
Easy handling
The instrument has the capacity to store up to 10 different programs that can be freely set up by the user. Each one of the programs can be started in immediate or delayed mode, without time limit. The instrument can easily be rotated via the four rollers mounted on the base. This allows the user to have fast and safe access to each one of the vessels.
Maximum safety standards for the user and the specimen
The individual cover for each one of the vessels reduces the emission of vapors to a minimum. The STP 120-2 and STP 120-3 versions incorporate a fume extraction system that - through a fan and an active charcoal filter - cleanse the vapors before being discharged into the air.
Alarms during the process
If the specimens remain inside a station for a longer time than the programmed time, e.g. due to a power failure, the display will show a message indicating the station number and the overtime spent in that station compared with the initially programmed time.
