There are two modifications of device: FASTAINER-16-25 (FS-16-25 – 16 stations and racks for 25 slides) and FASTAINER-16-12 (FS-16-12 – 16 stations and racks for 12 slides).
The staining of preparations is performed by sequential programmed movement of racks with slides from station to station where technological operations are fulfilled.
Working chamber is enclosed by transparent lid and is equipped with compulsory ventilation, which ensures the safe working with toxic reagents.
There is one station (#1) for drying (heating) with warm air flow, one station (#2) with flow-through trough (tap water), and one station (#9) for automated loading and unloading of racks with slides (only for FASTAINER-16-25).
The remaining stations are versatile – they allow to use them either for placement of troughs with liquid reagents or for placement of racks with slides. That gives the possibility to create an optimum configuration of device for each technique and even for each laboratory.
The device possesses extremely simple and reliable unique mechanics. The movement of racks with slides is executed by rotation not only in the horizontal plane, but also in up and down direction. When the rack rises from a liquid, it automatically inclines at the same time. Moreover, the rack rises from liquid with vibration. It facilitates draining of liquid from slides and the rack. Thus, the transfer of reagents between troughs is very low. Design of the manipulator mechanism provides fixing of a rack due blocking up of its handhold in case of rise. Rigid fixing of rack handhold gives the possibility to use high-speed modes of movement (during dipping, shaking, transfer from station to station and so on).
Control and programming is carried out with the color touch screen. Not only the sequence and duration of technological operations can be programmed, but also their parameters and regimes. For example, technological operations can be executed with activation with the different period, without activation and also by repeated dipping. The activation gives possibility to speed up different physical and chemical processes during technological operation. There is an option to set up the "draining time" for every station (the duration of delay of rack over trough after rise from the one).
The setting up of duration of time between launches of racks processing gives possibility of processing of several racks simultaneously.
There is also the possibility of the multiple increases in productivity due to installation of several troughs with reagent in which the longest technological operation is executed. Thus, FASTAINER gives several opportunities to make FAST the process of staining .
The number of stations is enough for providing most complicated techniques, such as Papanicolaou stain or different histological methods, H&E, particularly. The simple techniques: Romanowsky, Gram staining and so on, can be executed with high productivity. The productivity for Papanicolaou stain, for example, may be up to 150 slides per hour.
All these characteristics make both devices very versatile and efficient, despite their compactness. The unique simplicity of mechanics makes the devices quite reliable and cost effective.
