Drug Stability Test

The effectiveness and safety of drugs have attracted much attention, and it is also a livelihood issue that the country and the government attach great importance to. The stability of drugs will affect the efficacy and safety. In order to ensure the quality of drugs and storage containers, stability tests should be performed to determine their effective time and storage state. Stability test mainly studies whether the quality of drugs is affected by environmental factors such as temperature, humidity and light, and whether it changes with time and the correlation between them, and studies the degradation curve of drugs, according to which the effective period is presumed to ensure the effectiveness and safety of drugs when used. This article collects the standard information and test methods required for various stability tests for customers' reference.

First, drug stability test criteria

Storage conditions of drugs:

Note 1: If the long-term test condition has been set at 30℃±2℃/65% ±5%RH, there is no middle test; if the long-term storage condition is 25℃±2℃/ 60% ±5%RH, and there is a significant change in the accelerated test, then middle test should be added. And should be assessed against the criteria of "significant change".

Note 2: Sealed impervious containers such as glass ampoules can be exempted from humidity conditions. Unless otherwise determined, all tests shall be carried out in accordance with the stability test plan in the interim test.

The accelerated test data should be available for six months. The minimum duration of the stability test is 12 months for the middle test and the long-term test.

Store in refrigerator:

Stored in freezer:

If the product containing water or solvents that may be subject to solvent loss is packaged in a semi-permeable container, the stability assessment should be conducted under low relative humidity for a long period of time, or an middle test of 12 months, and an accelerated test of 6 months, in order to prove that the drug placed in the semi-permeable container can withstand the low relative humidity environment.

Containing water or solvents

The calculation of the relative water loss rate at a constant temperature of 40℃ is as follows:

First, different environmental conditions will have different effects on parts and cause them to fail, so the parts of the car need to be tested according to the relevant specifications to meet international requirements and meet the foreign market, the following is the correlation between different environmental conditions and product failure:

A. High temperature will make the product aging, gasification, cracking, softening, melting, expansion and evaporation, resulting in poor insulation, mechanical failure, mechanical stress increase; Low temperature will make the product embrittlement, icing, shrinkage and solidification, mechanical strength reduction, resulting in poor insulation, cracking mechanical failure, sealing failure;

B. High relative humidity will make the product poor insulation, cracking mechanical failure, sealing failure and resulting in poor insulation; Low relative humidity will dehydrate, embrittlement, reduce mechanical strength and lead to cracking and mechanical failure;

C. Low air pressure will cause product expansion, electrical insulation deterioration of the air to produce corona and ozone, low cooling effect and lead to mechanical failure, sealing failure, overheating;

D. Corrosive air will cause product corrosion, electrolysis, surface degradation, increased conductivity, increased contact resistance, resulting in increased wear electrical failure, mechanical failure;

E. Rapid temperature changes will cause local overheating of the product, resulting in cracking deformation and mechanical failure;

F. Accelerated vibration damage or impact will cause the mechanical stress fatigue resonance of the product and lead to an increase in structural damage.

Therefore, products need to pass the following climatic tests to test the reliability of components: Dust (dust) test, high temperature test, temperature and humidity storage test, salt/dry/warm recovery test, temperature and humidity cycle test, immersion/seepage test, salt spray test, low temperature test, thermal shock test, hot air aging test, weather and light resistance test, gas corrosion test, fire resistance test, mud and water test, dew condensation test, high variable temperature cycle test, Rain (waterproof) test, etc.

Its thermal conductivity exceeds that of any known metal. Heat pipe technology has been widely used in aerospace, military and other industries, since it has been introduced into the radiator manufacturing industry, making people change the design idea of the traditional radiator, and get rid of the single heat dissipation mode that simply relies on high air volume motor to obtain better heat dissipation effect.

Hydrogen Fuel Cell Environmental Simulation Test Scheme

At present, the economic development model based on the consumption of non-renewable energy based on coal, oil and natural gas has led to increasingly prominent environmental pollution and greenhouse effect. In order to achieve sustainable development of human beings, a harmonious relationship between man and nature has been established.

Lab Ovens and Lab Furnaces

Design with sample protection as the primary goal

Lab ovens are an indispensable utility for your daily workflow, from simple glassware drying to very complex temperature-controlled heating applications. Our portfolio of heating and drying ovens provides temperature stability and reproducibility for all your application needs. LABCOMPANION heating and drying ovens are designed with sample protection as a primary goal, contributing to superior efficiency, safety and ease of use.

Understand natural and mechanical convection

Principle of natural convection:

In a natural convection oven, hot air flows from bottom to bottom, so that the temperature is evenly distributed (see figure above). No fan actively blows the air inside the box. The advantage of this technology is ultra-low air turbulence, which allows for mild drying and heating.

Principle of mechanical convection:

In a mechanical convection (forced air drive) oven, an integrated fan actively drives the air inside the oven to achieve uniform temperature distribution throughout the chamber (see figure above). A major advantage is excellent temperature uniformity, which enables reproducible results in applications such as material testing, as well as for drying solutions with very demanding temperature requirements. Another advantage is that the drying rate is much faster than natural convection. After opening the door, the temperature in the mechanical convection oven will be restored to the set temperature level more quickly.
