Humidity chamber manufacturers brings new photostability chambers


Photostability chambers of Thermobalscientific, are made as per the ICH guidelines Q1 B guidelines option 2. These temperature control chambers are used to closely monitor temperature, humidity (optional) and light intensity on the drugs and drug substances.


This humidity control chamber come with the following light exposure options in it.

  • Exposure of cool white florescent light for 1.2mil lux hours and UV-A Light for 200 watt hours per square meter on the test samples.
  • Combined light exposure or individual light exposure with automatic light cut off system after exposure is achieved.
  • The light exposure data is captured in the system with respect to date and time along with temperature and humidity (optional).
  • The light exposure data can be printed directly on the printer (printer interface facility) or can be hooked on to the software. (PC Interface facility)
  • Light tubes are mounted horizontally on the tray which gives direct light on to the test samples.
  • UV Light supply is cut off when the door is open as a safety measure.

The usefulness of this humidity control chambe primarily rests on its thoughtful construction. The following are the construction features of Photostability chambers.  

  • Constructed and fabricated on fully automatic CNC machines thereby giving consistency in performance and an aesthetic look.
  • Elegant ABS moulded control panel.
  • PUF insulation on fully automatic machine leaving no gaps and with sleek body design.
  • Direct % RH electronic capacitor type humidity sensor (in case humidity parameter is selected).
  • Chambers are provided with effective air circulation system, refrigeration system, humidity system, full view observation glass door and stainless steel trays.
Stand by refrigeration system and stand by humidity system is provided (as an optional feature as a redundancy).

Walk-in BOD incubators: Effective temperature control chambers


Walk-in BOD incubators are required for cost-effective and reliable incubation. These incubators are used for high volume incubation in industries and are capable of monitoring the environment with a precise combination of temperature. These walk-in BOD incubators are available in standard size, however, thermoabscientific, a reputed incubator manufacturer, offers custom made incubating chambers to suit the layout and requirement.

Thermolab Scientific walk-in BOD incubators have the following safety features available:

  • Safety cut offs and alarms at centrally located places including one at the security gate.
  • Special door lock, which can be opened from inside even if locked from outside.
  • An emergency bell switch provided inside the chamber and is attached with a door open alarm.
  • Dedicated Safety system to shut off the temperature and humidity control chamber in case of overshoot or undershoot of temperature with audio visual alarm.
  • As an additional safety feature the cooling cabinet has thermostatic safety system. 
  • For better tracking all the alarms and events are logged in the software.

This temperature control chambers are built with the following Control Features:

  • Microprocessor-based PID controller with auto tuning for accurate control of temperature.
  • Printer interface facility to store data and to print it directly on a printer with variable print time interval.
  • A PLC system for an auto changeover of standby systems and other event logging and monitoring purpose.
  • Door Access Security System with smart cards / bio-metrics and software to authorize and to monitor door accessibility.

Apart from the safety features and control features walk-in environmental chambers also has software for faster performance. Its software has the following features in it.

  •  21 CFR part 11 USFDA compliant software with validation documents.
  • Secured audit Trail.
  •  Multi level security password with aging and history.
  • Electronic signature.
  • Web based (Ethernet) online remote monitoring. 
  • GSM alarm system (mobile alert) 
  • Data of door access security system in software with remote options.
  • All the events, utility, working status, all the alarms are logged in the software.
  • Records in graphical and in tabular form.
  • Reports of mean Kinetic Temperature Reading.
  • Works on 440 V AC three phase 50Hz (country specific). 
  • Complete with extensive DQ, IQ, OQ and PQ protocols as per the International guidelines along with calibration certificates.
