• What is Walk In stability chamber :

Walk in Stability Chambers are specially designedequipment for the testing of products and also to determine their shelf life such as drug, electrical components, industrial materialsetc which enables you to tweak parameters like temperature, humidity to conduct a thorough check over varied conditions.

  • Use of the Walk in stability chamber :-

It help for the testing of drugs in varied conditions of temperature, humidity, pH, radiations etc. They are also used to check for how long the product will be efficient to use.

  • Working principle of Walk in stability chamber :

The Walk in Stability Chamber consists of motor and blower arrangement for air circulation to achieve uniform temperature & humidity across the working area. It is a well-insulated double walled chamber and can maintain the temperature & humidity as per the set point on the controller within the specified limits.

  • What is the Walk in stability Guidelines :

    ICH Guidelines , WHO Guidelines, cGMP guideline for shelf life study.

  • What is the difference between stability chamber and walk in stability chamber?
  • In stability chamber you need to stand in front of the chamber and open the door to load or unload the sample .
  • In walk in stability chamber , you open the door , go inside the chamber and walk through the chamber to load, unload or change the sample and during this you can close the door.
  • Usually walk in stability chamber is bigger version of the stability chamber.
  • Normal stability chamber comes around max size upto 3000 Litres. Hamco Walk in stability chamber starts from 4000 Litres upto 100000 Litres.
  • Objective of Walk in Stability Studies
Objective Type of study Use
To select adequate formulations and containor closure system Accelerated Development of the product
To determine shelf-life and storage conditions Accelerated and real time Development of the product and of the registration dossier
To substantiate the claimed shelf-life Real Time Registration dossier
To verify that no changes have been introduced in the formulation or manufacturing process that can adversely affect the stability of the product Accelerated and real time Quality assurance in general, including quality control
  • Storage Conditions :
Conditions Name Storage temperature (C) Relative humidity (%)
Real Time 25 C +/- 2 C 60 % +/- 5 %
Long Term 30 C +/- 2 C 65 % +/- 5 %
Long Term 30 C +/- 2 C 75 % +/- 5 %
Accelerated 40 C +/- 2 C 75 % +/- 5 %
  • Why 21 CFR Software compliance require?

The major challenges that the auditor has that all the data submitted of the testing should be authentic and non tempered. This will only possible if it is 21 CFR Complied data is there. Thats why it is important to have stability chamber with 21 cfr complied compliance.

  • What is DQ,IQ,OQ,PQ documents?

Normally Manufacture gives the User set of documents or say checklist kind of documents which on completition of doing will check the Stability chamber thoroughly on all the parameters.

Terminology Full Form Use
DQ Design Qualification This confirm that How de design the chamber and why certain component has been selected.
IQ Installation Qualification This confirm How to Install the equipment by checking all the component Make, sl No and certificate, Preinstallation requirement and Utilities.
OQ Operational Qualification This confirm the operation wise checking of all the paramenter of the equipment.
PQ Performance Qualification This confirm the performance qualification of the stability chamber.
  • What is Validation of the chamber and its protocol?

Validation means checking the performance of the chamber on accuracy and uniformity by placing sensors at different location for specified time interval and checking report for its Confirmatory. Normally Validation will be Onsite ( Checked by the Manufactory on its location ) and offsite at Buyer location. It will be empty, Part load and Full Load depending on the validation protocol.

Temperature Safety :-

When Temperature deviates higher side than their prescribed limits , the Heater will be cut off by switchgears & if still go higher than by Thermostate. It generated alarm and horn the buzzer if it deviates. Once it reach within the range , the heating system reset automatically.

When Temperature deviates lower side than their prescribed limits , the Compressor will be cut off by switchgears & if still go lower than by

Thermostate. It generated alarm and horn the buzzer if it deviates. Once it








reach within the range , the Refrigeration system reset automatically.

Humidity Safety :-

When Humidity deviates higher side than their prescribed limits , the Boiler will be cut off by switchgears. It generated alarm and horn the buzzer if it deviates. Once it reach within the range , the Humidity system reset automatically.

Low water level safety , In case of Insufficient water in boiler tank , the Boiler is Cut off and it generates the alarm and horn the buzzer . When it resumes, it starts automatically.

Human Safety :-

All the component has individual MCB for Overload and trip protection.
