With outstanding accuracy & total reliability, the SAKAV climatic chamber is by far the specialist for the precise, standard compliant simulation of constant climatic conditions. At the same time the SAKAV climatic chamber provides a low cost alternative to expensive test chambers or test rooms.
For stability tests, durability tests & photostability tests, long term storage must carried out & documented according to internationally valid, or under exactly defined conditions.
Many well-known Pharmaceutical companies, all over the world, use the climatic chamber for this demanding task. There is no area in which the climatic parameters have no influence on materials or their life span. The climatic chamber SAKAV has unlimited uses for all applications under constant climatic conditions, from the defined conditioning of polymers to the conditioning of Tobacco, this is proven by the thousands of installations in the most varied Industry area.
SAKAV GUIDELINES
The SAKAV climatic chamber is especially suitable for the carrying out of stability tests on drugs & drug substances according to the current guideline, in order to find out whether the substances to be tested remain stable during a defined period of time under the aging factors temperature & humidity, the SAKAV climatic chamber was developed in accordance to the requirements stipulated. In the internationally binding guideline & fulfills these requirement completely.
Stability tests carried out in accordance to the above guideline are carried out under the following conditions.
1) ²Long term² Test during 12 months at 25°C (±2°C) 60% Rh (±5%)
2) ²Accelerated² Test during 6 months at 40°C (±2°C) 75% Rh (±5%)
3) ²Intermediate² Test during 6 months at 30°C (±2°C) 60% Rh (±5%)
Firstly the sequential test, i.e. in addition to the temperature and humidity, the short period photo-ageing is separately carried out with extremely strong light with a defined lighting specification -or the simultaneous ageing in the SAKAV Climatic Chamber with temperature, humidity and light. In the latter case, it can be fitted with the respective optional light. For further information please refer to the technical specifications.
Construction:
Double Walled construction with inside madeS.S.304 and outside M.S. powder coated having leak proof joints for strength durability and impermeability through moisture.
Insulation:
Inside S.S. and outside M.S. will be insulated with special polyurethane foam (PUF) / glasswool insulation of 3" thick to prevent loss of cooling and heating effect. All the joints are leak proof joints for strength durability and impermeability through moisture.
Finish:
Externally powder coated in pleasant colour and internal polish buff for long life and good finish of the chamber.
Heating System
The heating system consists of S.S. nichrome wire embedded 'U' shape air heaters that are left in the chamber in a duct. The heating capacity will be of 1 KW approx. to take the temperature upto 800C from ambient.
Cooling System
Cooling system with high efficiency compressor with state of art Bypass system to avoid over loading the compressor during long duration test.
The cooling system consists of compressor of Kirloskar make with other standard accessories such as solenoid valve drier, cooling fan, condenser, evaporator etc. As per the specific temperature requirements.
Humidity System
It is achieved by steam injection with the help of boiler that is fitted with ball cock valve.
Control System:
All the types of humidity chambers are with microprocessor based PID controller with digital display. It will display set values, as well as actual values with a control accuracy at + 0.20C. The control panel is complete with contactors, fusers, connectors, indicator lamps and wiring ass per IS code.
Trays:
Two nos. Stainless steel trays will be provided with each chamber, however arrangement will be made to accommodate total 4 nos. trays
Power:
Works on 230 V AC single phase.
