Photostability The ICH Harmonized Tripartite Guideline on Stability Testing of New Drug Substances and Products is an internationally recognized document referencing the need for stability testing.

The U.S. What is a good humidity level in your house FDA has adopted the annex document Q1B, which states that products should be evaluated to demonstrate that light exposure does not result in unacceptable changes. What is a good humidity level indoors Should changes occur, the drug manufacturer may reformulate or repackage the product to prevent further photo degradation.

Option 1: A light source designed to produce an output similar to the D65/ID65 emission standard referenced to ISO 10977. What is a good humidity level inside a house Such sources include full spectrum fluorescent lamps, xenon or metal halide lamps.


What is a good humidity level inside during summer We offer a custom-made full spectrum fluorescent lamp which combines visible and ultraviolet-A outputs.

• A cool white fluorescent lamp to produce an output similar to that specified in ISO 10977. What is a good humidity level inside during winter BES offers a custom-made cool white lamp to specifically replicate this standard.

• A near-ultraviolet lamp with a spectral distribution from 320–400 nm. What is a good humidity level outside with maximum emission between 350 – 370nm. What is a good indoor humidity level in summer Significant portions of UVshould fall in the bands of 320 – 360 nm. What is a good indoor humidity level in the winter and 360-400 nm. What is a good inside humidity level BES also offers a custom-made ultraviolet-A lamp to meet these specific emission guidelines.

Our precise air control system ensures conditioned air is distributed uniformly across your product shelves. What is a good level of humidity in a house A stainless steel impeller moves the air through the conditioning components within the enclosed plenum.

Air is then distributed and returned through the plenum’s side wall portswhich are specifically arranged for maximum uniformity and efficientthermal transfer. What is a good level of humidity indoors The conditioning system features include:

Our double-wall chamber construction provides you with years of continued, trouble-free use. What is a healthy humidity level for a home The interior is heliarc-welded at the seams to form a hermetic seal which prevents moisture from migrating into the insulation.

• Closed-cell urethane insulation for superior high/low temperaturestability and minimal heat transfer. What is a healthy humidity level in a home The door is also completely foamedfor thermal performance and rigidity.

BES incorporates a proportional liquid/hot gas refrigeration design to maintain close tolerance temperature control and rapid acceleration to your setpoint. What is a healthy humidity level in a house The compressor life is extended by modulating refrigerant flow as required. What is a healthy humidity level in your home All facets help maintain the life of your chamber under photostability conditions. What is a healthy humidity level indoors The proportional refrigeration system features are as follows:

• Air-cooled, hermetically sealed compressor with environmentally safe, non-toxic, CFC-free refrigerants. What is a healthy indoor humidity level Optional water-cooled units are available.

• Expansion valve refrigeration control provides higher heat removal capacity than conventional capillary tube designs and provides immediate response to added heat loads.

BES’ upright floor models provide up to (3) simultaneous light studies with adjustable, uniformly-controlled light levels across your product shelves. What is a healthy level of humidity in a house Intensities are easily and individually controlled at each light bank with a microprocessor-based controller and a photo diode sensor to provide a fully automated, closed-loop control system. What is a high humidity level in a house The features of each light bank are as follows:

• Interchangeable cool white, near-ultraviolet, full spectrum, and dual source cool white/UV banks designed to meet Options 1 and 2 of current ICH/FDA guidelines. What is a high humidity level outside Three banks are accommodated in the upright floor model; one bank is provided in the benchtop model.

• Independent light level and timing controls are provided at each individual light bank. What is a normal humidity level for inside a house Light bank timers provide precise testing durations.

• Shelf-mounted telescoping sensor capable of accurate measurement and control of light levels through varied temperatures, product heights and reflective conditions. What is a normal humidity level in a home Each light surface has a controlling sensor.

We provide high intensity, uniform light levels through the use of optimum bulb positioning, highly reflective materials, and high output biax lamps. What is a normal humidity level in a house Extensive R&D has led to the unique bulb layout suitable for uniform exposure in 7-lamp, 4-lamp and dual source operation. What is a normal humidity level inside a home Special high-grade specular aluminum covers all vertical surfaces and provides ultimate reflectivity, resulting in excellent uniformity and higher light levels. What is a normal humidity level outside The biax lamp design allows for 40 watt T-5 lamps to fit into a system normally capable of holding only 15–20 watt T-8 lamps. What is a safe humidity level in a home This means higher light levels and output per area than competitive light chambers. What is an acceptable humidity level in a home A popular feature of our lighting system is the dual source light bank. What is an acceptable level of humidity in a home This is standard on the benchtop model and available as an option on the upright floor model. What is best indoor humidity level Both cool white and ultraviolet-A lamps are integrated into one single bank and independently controlled by a corresponding light sensor for a total of two light systems at each shelf (shown above). What is good humidity level in home Each source may be operated independently or simultaneously with light uniformity within ±10% in the standard 70% marked region (shown above). What is good indoor humidity levels Alarm/Monitoring System

Our control panel features standard high/low visual and audible alarms for temperature, humidity and lighting. What is healthy indoor humidity level The alarms offer you instant visual indication and time-delayed audible indication for quick notification. What is humidity level in a house The temperature and humidity alarms automatically shutdown specific mechanical equipment. What is ideal home humidity level The alarm monitoring system features include:

• Standard N. What is ideal humidity in a house O./N. What is ideal indoor humidity level C. What is ideal relative humidity indoors dry alarm contacts for remote monitoring of each parameter. What is normal humidity in a home There is one temperature, one humidity and one general lighting alarm.

Our user-friendly microprocessor-based control system incorporates a P.I.D. What is normal humidity inside a home controller with a subpanel-mounted process board. What is normal humidity level in a house This board features an L.C.D. What is normal humidity level in home in winter backlit display and 4-function membrane switchpad. What is normal humidity level indoors The system includes digital setpoint and process display of your controlled parameters, while indicator lights monitor power and alarm functions. What is normal relative humidity in a house A non-volatile memory retains your setpoints for restart in the event of a power failure. What is optimal humidity in a home All controls are mounted on a hinged access panel for ease of maintenance. What is optimum humidity in a house Features include:
