Refrigerated Floor Model Shaker Incubator SMI-159A



JINDAL Refrigerated floor model shaker incubator SMI-159A  are designed for day-to-day laboratory routine work.



The external body of the incubator is made of galvanized steel sheet with baked-on finish having powder coating & the internal chamber is made of high-grade polished corrosion resistant double pane insulated stainless steel. The chamber is insulated with high density Polyurethane insulation to prevent thermal losses. The complete shaker is mounted on a heavy angle frame structure on all the sides & consists of castor wheels cum jack system for easy movement. A front opening door with a glass window facilitates the inspection of samples without disturbing the temperature. The door consists of attachable light shielding plate for safety. The unit is provided with 02 Nos. removable stainless steel shelves. Forced air circulation inside ensures uniform temperature distribution throughout the chamber.

The shaker consists of a triple eccentric drive mechanism with 25mm stroke displacement. A brushless induction motor along with a feedback signal provides accurate speed.

Heating is done by finned heaters (250 Watts) & are placed near to the cooling tubes. The refrigeration is done by a highly energy efficient ISI marked hermetically sealed compressor (1/6HP) which operates on CFC free refrigerant. The refrigeration system also controls the humidity inside the chamber.

The temperature range is from 4ºC to 80ºC controlled by a digital microprocessor temperature indicator cum controller within an accuracy & stability of ±0.10C.The temperature fluctuation in flask at 370C is ±0.10C. The heaters linked to the microprocessor run on the PID function & the compressor runs in On/off operation. The temperature can be set in the inc./dec. of 0.10C. The shaking speed can be adjusted from 10 to 500 rpm ±1 rpm within increments of 1rpm& is controlled by the precise microprocessor controller. A bright digital LCD 7” multicolor touch screen displays & monitors all the set parameters including temperature, Speed & time (1min to 999hr). The operator can program multistep programming (4 steps) in each program. Built-in self-diagnostic system along with over & under voltage protection system switches off the system in case of fault. Built in automatic shaking speed adjustment in case of unbalanced load/vibrations/shocks.

Independent alarm system (audio-visual) warns if the temperature deviates ±10C (adjustable) from the set point & speed varies ±2 rpm from the set speed (or even installed platform).

An audio-visual alarm at the end of the digital timing cycle is an added advantage. Bright LCD displays temperature, time & shaking speed digitally simultaneously on the same screen. The microprocessor controller is designed to retain parameters during power failure & restarts the unit automatically. Built in independent over temperature protection & cut off system. Built-in data logging can be done with an on board USB port by using a pen drive & the complete system can be remotely operated through a computer by using on board Ethernet port.

An internal fluorescent light provides better visibility of samples. The chamber also consists of a built in rust free power socket for efficient operation.

The 100 Ltr. capacity chamber consists of 18”X18” universal platforms to hold various spring based clamps. The platforms can be interchanged easily as per the operator’s requirement.

Universal platform designed to accommodate the following:

36 X100 ml flasks or 250ml X25 flasks or 16 X 500 ml flasks or 9 X 1000 ml flasks

The shaker also has a static incubation shelf facility for incubation of petri plates apart from the shaking & is provided with 2 shelves.

Stainless steel clamps to hold various flask sizes 50mL, 100mL, 250mL, 500mL, 1Ltr.are provided along with the machine.

The incubator comes with a three-point calibration certificate from an NABLNABL-accreditedoratory.

The instrument is designed to operate on 220V Single Phase AC Supply with overcurrent protection system.
