Spin Tissue Processor STP 120

Features

• A worldwide unique technique

Tissue processing is a technique than 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.

• 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, a 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 a 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.

Tissue processing achieves by this method almost similar results to those obtained with vacuum systems!

• 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 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 a 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. Optional adaptor for the laboratory general extraction system.

In case of a power shutdown, the specimens are automatically lowered inside the vessel by means of a battery to protect them against desiccation and solid paraffins. Once power is restored, the instrument resumes the program at the same point in which it was interrupted. lf it is a long power failure and the paraffin baths become solidified, the safety program will be activated. The instrument will then wait for the baths to be fully liquified before going ahead with the change to the paraffin baths.

Emergency motions can be implemented through the battery, such as moving the basket up and down or station change (as long as the basket is not inside a solidified paraffin bath). The instrument is also equipped with an emergency stop button. It is possible to interrupt a program for reloading or advanced unloading of samples.

• 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. The acoustic and visual alarms can easily be identified by the user. The keyboard can be locked by the user to avoid an inadvertent change of the process parameters during operation.
