Electron Microscope


Welcome to Absotec Scanning Electron Microscope

Service Laboratory


Absotec found in 2000 in the LED business. We design and manufacturing of high efficiency LED with automation system. Our business starting from Malaysia and expand to Thailand in 2007.

In 2007, we set our positioning in as the leading in Particle Anaysis by SEM/EDS technology in Thailand. Our produtct portfolio expand from this strategy to the most advance SEM/EDS/EBSD and uXRF. Thank you to all our partner and key account customers that confidence in us. Our skill bring us to most important attention in HDD and Forensics. Absotec becomes the leader of Particle Analysis by SEM/EDS today.

Nov 1st 2018, Absotec would like to announce the opening the SEM and MicroXRF Service Laboratory. Our SEM is the most advance to support the automate particle analysis. We can support Gun Shot Residue analysis for forensics application, Mineral analysis, and all other particle analysis application. We also have M4 Tornado which is the automate elemental mapping for large sample, wet sample, rough sample, and non-conductive sample without any sample preparation. This bring us to the complete line from macro to micro analysis.

Diamond WireTec

Diamond WireTec

Highest Precision Diamond Wire Cut for Laboratory

Diamond WireTec

The diamond wire saw type DWS.100 is a table saw in horizontal design so that the smallest cut-offs can be observed with the naked eye or also by means of an attached microscope. Minimum roughness and evenness with Rotary drive.

The maximum workpiece cutting area is 90 x 90 mm and the recommended diamond wire thickness is 0.08 to 0.35 mm. The continuously adjustable wire speed goes from 0 to 4 m/s. To ensure a constant cutting pressure, the feed is done by gravity. Workpieces can be cut both wet and dry.
