Corrosion Test Chamber

Product Details:

The Sulphur Dioxide Test Chambers from Weiber are Corrosion Test Chambers used for testing the corrosion resistance of metallic surfaces and outer protective layer of coatings. They are used to create a highly corrosive environment rich in corrosive gases and natural humid conditions to induce accelerated corrosion in protective coatings of machines and equipments, electrical items, electronic parts and components, mechanical constructions, automobile and aircraft parts and components etc. Since the corrosive action of Sulphur dioxide also depends on specific temperature and humidity conditions and the presence of other contaminants, the Weiber Sulphur Dioxide Test Chambers are designed to create optimal conditions of temperature and humidity and also make provisions for introducing impurities and contaminants. These equipments operate across a wide temperature range, creating variations in the working temperature to mimic a natural weathering environment.

The SO2 Test Chambers from Weiber are designed in accordance with international standards and can be completely customized according to specific requirements. They use advanced and sophisticated technology to ensure safe and reliable operation and are easy to use and maintain. These equipments are available in visually appealing aesthetic designs and find widespread usage in industrial manufacturing units and research organizations. They are designed for diverse and versatile applications and often function as fog test chambers and automobile accelerated corrosion test chambers.

Product Details:

Drosophila melanogaster, commonly known as fruit fly is one of the most common genetic model organism that is used in several laboratories across the globe for the study of genetics and other biological sciences. There has been a lot of emphasis on Drosophila research, especially since it was established that a vast majority of human disease genes have parallels in the Drosophila genome and therefore conventionalDrosophila genetics can be used to place human disease genes of unknown function in the context of functional pathways. The Drosophilagenome also shows high degree of homology to the mammalian genome and is often used for the identification and characterization of cellular processes and major signaling pathways that are conserved from fruit flies to humans. The insect has a short generation time, allowing large genetic screens and providing a cost effective solution to studying population genetics.

Most of the scientific research laboratories engaged in Drosophila research generally employ Drosophila research chambers for rearing of these insects in laboratories. These equipments provide a highly controlled environment for optimum growth and development of the fruit fly species. However, the laboratory reared flies may feature altered behavioral phenotype as a result of genetic drift over time and therefore, it is advisable to change the fruit fly stock every few hundred generations to protect the natural gene pools of these organisms. This chamber also known as Drosophila Test Chamber and Fruit Fly Test Chamber.

Operating Principle:

• The test condition are controlled by microprocessor based control system. Control is governed by the 32 Bit I/O system with integrated soft PLC. A web server can place test and diagnosis information in the intranet via Ethernet if desired. The temperature to be provided according to the test are:
• • The test method of salt water:
  • The lab: 35oC ±1oC
  • The saturated air barrel: 47oC±1oC
  The test method of corrosive resistant:
  • The lab: 50oC±1oC
  • The saturated air barrel: 63oC±1oC
• A salt solution is sprayed into the test chamber using the venture principle through a nozzle located at the top of the test space. The compressed air required is heated in a pressurized humidifier and saturated with moisture before itenters the test space.
• The brine solution in the venture nozzle feeder vessel is kept at a constant level by recirculating supply.The heating in the test chamber ensures uniform temperature conditioning to the required set temperature.
• Condensation generated is drained away through a floor drain, and the corrosive test chamber atmosphere is vented through an exhaust vent.

Construction Details:

Weiber provides better automatic controls for the chamber by integrating HMI and PLC together. This special feature is compelling alternative to traditional methods and provides a simplified, reduced cost control system architecture.
It works by following operating steps:

• Sensors measure the physical quantity like temperature and convert them to electrical signal
• The actuation device acts upon that electrical signal
• At HMI interface between operator and chamber occurs.
• The machine operates with the logic design controls controlled by software.
• This signal is sent to the chamber by logic control devices and the chamber operates.
