Environmental Test Chambers

Our LABTOP ® Stability Test Chambers are specifically designed for conducting various types of stability and shelf life studies on drugs and drug substances under controlled conditions. Besides this, our environmental test chambers are widely used for seed testing and biological studies. There application can also be seen in testing on electronic & mechanical components, cement plants, packing industries etc. Our LABTOP environmental test chambers are in accordance with the international quality standards like ICH, WHO guideline, and USFDA rules.

Special Features of Environmental Test Chambers

• The use of CE approved micro-controller ensures precise temperature control.
• PID controller (Imported, Auto tuning type.).
• An electronic capacitance type sensor keep a watch over the % RH and gives the direct digital read-out of the same.
• An effective R-134a environment-friendly refrigeration system with CFC free compressor and time delay facility.
• Windows based communication software enabled PC interface.
• Programmable timer which is based on micro-controller, meant for chamber illumination.
• Foamed- in-place PUF insulation which ensures temperature stability and reduced energy consumption.
• Option of audiovisual alarm in case of temperature deviation from the preset value.

Cabinet Construction and Refrigeration System
The cabinet of Labtop Chambers are insulated with high density CFC free Poly Urethane Foam. Interior of chambers is mirror finish stainless Steel (304 SS, 0.8 mm thick). The exterior is white powder coated (1.0 mm thick) mild steel and the door has magnetic gasket with a keyed door lock. Stainless steel trays are provided for storage inside. The cooling is effected by hermitically sealed compressor of high quality. GMP models are in total stainless steel (Inside S. S 316 with mirror finished and outside. S 304 dull finish.) is also manufactured by Skylab.

Optional Accessories Stand by Refrigeration system : The ready to use standby refrigeration system is of great help in case of regular system failures. This standby system is comprised of compressor, condensers, evaporator, and other accessories.

Optional Accessories : A four point temperature and four point humidity scanner fully equipped with sensors, printer interface, and data storage space.

Safety controller : A dedicated safety controller having a separate sensor particularly for switching off the power supply in case of overshoot and undershoot of temperature, producing an audiovisual alarm.

Data Scanner : Four point temperature or four point humidity or eight point temperature or eight point humidity data scanner. This scanner is complete with all the necessary sensors, printer interface, and data storage facility.

Printer Interface : Giving the advantage of storing print records on the printer with set values and process values, date and time according to the variable print time interval. Also, makes online and offline printing of data possible by providing data storage facility. This facility is appropriate for printing with 80 column dot matrix printer.

Software : A web-based communication software complete with RS 485 multi dropping to monitor multiple chambers and complied with CFR 21 Part 11.

PC Interface and data management : The advantage of remote monitoring and data logging is provided by this PC interface having the facility of communication. This interface also allows the creation of tabular as well as graphical format reports.

PLC system : This programmable logic controller or PLC system is meant for the purpose of automating the process of changeover of standby systems and for accomplishing other event management tasks. This advanced PLC system is equipped with a 3.7” clear LCD, which has the special security feature of touch screen security lock to prevent any kind of unauthorized tampering.

Temperature & Humidity Sensor : This sensor is an electronic capacitance type temperature and humidity sensor. It avoids wick, cup, and water.
