Castor wheel mounted cabinet is double walled with inner chamber of Stainless steel sheet of grade SS 304 and outer wall of heavy gauge PCRC steel. sheet duly degreased and pre treated with primers for rust proofing duly painted with attractive stove enamel or powder coated
The temperature inside the stability test chamber is controlled by intelligent programmable temperature controller and indicator. This controller is based on the microcontroller nano watt technology and its ergonomic design suits for any specific requirement of the photo stability test chamber like Data logger facility, Thermal and DOT Matrix interface, direct data load facility in computer office automation software like MS-Word and Excel and many other features listed in the specification bellow.
40% to 95% RH (Accuracy: + 2%)
Accurate Micro processor Based Humidity Control System:
The WEIBER” Stabiliy Chamber uses a microprocessor based, electronic humidity sensor detector is an exact logarithmic function of the humidity concentration in the environment of the chamber between source and detector. Advanced design provides a very stable drift-free output requiring less frequent calibration.
Our Stability Chamber conforms to the illumination requirement as per the International Conference on Harmonisation of Technical Requirements for Registration of Pharmaceuticals for Human Use (ICH) ICH GUIDELINES (ICH Q1B). The unit is provided with four fluorescent light mounted in a diffuser enclosure at the top of the chamber providing minimum illumination level of 1.2 million lux ,which is effectively controlled through a programmable illumination controller.
Unit is fitted with door operated illumination lamp inside the chamber. 40 watt/120 volt replacement light bulb fits inside the illumination cavity of the chamber.
The gap of 75 mm between the outer and the inner wall is filled with special grade glass wool to prevent thermal losses.
Mineral Glass Wool Insulation:
Glass mineral wool is one of the most environmentally friendly, stable and sustainable insulants available. Glass wool is incombustible by nature. Euro class classification is A. It does not propagate flames and toxic smokes. Thanks to a dense entanglement of materials with a low conduction and trapping a great amount of air, glass wool is a an excellent thermal insulant. The thickest it is, the best thermal resistance it has, thus reducing heat losses in our equipments for better sensitivity and economical operations. And its impact on the environment in manufacture, use and disposal is minimal.
Air circulation:
Triple walled back of unit is fitted with two air circulation fans for maintaining temperature uniformly throughout the chamber.
- Vacuum impregnated stator winding with dr. back varnish under red baktol.
- Non-Hygroscopic
- Best IR value
- Bright bar (EN - 8 class) shaft.
- Bush bearing of branded companies.
- Surge comparison testing in fans and pumps eliminates into turn short circulating of the stator.
- Pressure die-casted-rotor manufactured with zero error.
- Boats of high accuracy.
Full view inner glass/perspex door permits inspection of specimens, without disturbing the chamber temperature . Lock and Key arrangement is provided in the double walled outer door.
Refrigeration unit is formed by ISI marked compressor/cooling kit. Of Kioloskar Copeland or Tecumseh.
The front panel is provided with separate indicator lamps for main heating and incoming voltage. Digital Temperature controller cum Indicator and voltmeter.
Shelves:
The unit is supplied with three shelves of stainless steel sheet.
Voltage:
To work on 220/230V A.C. supply.
