The A3 Atomic Absorption Spectrometer is a high performance automated instrument designed to meet the requirements of the modern laboratory. Due to its versatility and performance it can be used for a wide range of applications.
Three flame options are available to the user with the Air/Acetylene being the standard configuration. This flame can be used for nearly all standard elements while the N2O/Acetylene and the Air/LPG (natural gas) are available as an option for the more demanding of elements. All three flame configurations offer coded burner for full safety protection.
The graphite head is fixed into the optical path to maximize performance and eliminate drift. The temperature of the transversely heated graphite tube is accurately controlled by means of a precision feedback system. Pyrolytically coated platform tubes are supplied as standard to improve the performance and eliminate many analytical problems associated with this technique.
The flame and graphite furnace can be changed over by a simple selection in versatile AA Win Pro software.
â—† Easy to use, complete software control
â—† Integrated safety precautions for user protection
â—† Flexible configuration for a wide array of industrial apps
â—† Time-saving high speed analysis

Motic’s new AE2000 Inverted Microscope is designed for routine live cell inspection with an easy and flexible set up, ideal for University, routine-clinical, and lab environments. The model’s main applications offer superior image quality when viewing cell cultures in microbiology, living organisms and tissue culture samples.
The newly designed Binocular Ergo tubes with 360° swiveling “butterfly” design offers the most comfortable observation position, especially useful for prolonged sample viewing. The auto on/off function of the power supply extends the lifespan of the sample and light bulb and at the same time saves energy. Another added feature, a modular interchangeable illumination concept, allows for the easy transition from Halogen to LED to fulfill a wide-range of customer viewing expectations. The improved phase contrast quality of the model makes the instrument suitable for a greater range of applications that demand precision optics. The entire microscope including optical system is manufactured now completely Lead Free, following the International RoHS regulations.
