High Stability Pharmaceutical Stability Chambers/ Comprehensive Drug Test Chamber Manufacturer India/ Drug Stability Test chamber – single door/drug Stability/ Medicine ICH Stability Climatic Chamber/ Pharmaceutical Stability Test Chambers/Stability Testing Chamber lab research Stability Testing Chamber in controlled environment/Drug Stability Test Chamber

Yatherm Stability test Chamber fulfills the advanced specifications for pharmaceutical, food & defense laboratories. Modern & latest designs of cabinet equipped with advance HCFC free refrigeration system, PLC operated temperature controlling device with Rust-free humidity Reservoir. We offer thick PUF insulation for energy conservation with a safe environment for the user. Stability test chambers are designed for continuous operation under the observation of scientists for up to 90 days without any interruption.
Pharmaceutical industry follows chemical & drug stability guidelines to perform test – drug production and development shall be specified temperature, humidity and light irradiation test. These tests are divided into 4 to 5 categories and these categories mentioned below with standard temperature, Humidity and light requirement.
High humidity test: Temperature of 25 ℃ ± 2 ℃, humidity 90% R.H ± 5%, or 75% ± 5%. Generally high humidity tests are performed between 85% to 95% relative humidity at ambient temperature.
Acceleration test: 40 ℃ ± 2 ℃, 75% ± 5% or 30 ℃ ± 2 ℃, 65% ± 5% .; Packaging in pharma industry formulations for semi-permeable containers, like plastic sealed boxes, PVC bottle drops liquid, Nasal drops should be 40 ℃ ± 2 ℃, 20% ± 5% or 25 ℃ ± 2 ℃, 20% ± 5%. This test helps in analyzing the impact of climate and transportation on drug formulation
Long-term test: Ambient temperature 25 ℃ ± 2 ℃, Relative Humidity 60% ± 10%; in pharma industry formulations for packing in leakproof Plastic containers, such as PVC bags solution, PVC bottles for eye drops & nasal drops should be 25 ℃ ± 2 ℃, 40% ± 10%.
Additional tests in moderate conditions: 30℃±2℃, 40%±5%
High temperature test: 40 ℃, 60 ℃

Stability test chambers are different from the temperature Humidity test chamber in terms of long-term Storage Testing with precise and accurate controlling. Stability test chambers are highly accurate & stable to maintain the standard environment for pharmaceutical drugs. Yatherm Stability test chambers come with a safe & sound performance for temperature utilization inside the chamber. ICH Stability test chambers have a wide working range that meets the requirements of the International standard as per ICH guidelines Q1A (R2) for stability testing.
Fog-free viewing window and interior light make viewing workspace freely and observe the test under the best conditions. The left side of the chamber with a diameter 50 mm (support customized) cable port for the power-on test. The optional electronic humidity sensor is used on all test chambers for accuracy and minimal maintenance. Safety relay connection is provided to protect your device under test by removing power to it when the chamber is not running. The touch screen controller is designed to save chamber programming and setup time with temperature limits an alarm to protect your product.
