Sem model quanta 250 feg

Manufactured by Thermo Fisher Scientific
Visit Supplier
Sourced in Netherlands

The Thermo Fisher Scientific Quanta 250 FEG is a scanning electron microscope (SEM) designed for high-resolution imaging and analysis of materials. The Quanta 250 FEG utilizes a field emission gun as the electron source, providing high-brightness, high-resolution imaging capabilities. The system is equipped with various detectors for secondary electrons, backscattered electrons, and energy-dispersive X-ray spectroscopy (EDS) analysis.

SEM Fracture Surface Analysis

The separated files were ultrasonically cleaned in 70% ethyl alcohol for 15 minutes before examination under SEM (SEM Model Quanta 250 FEG [Field Emission Gun], FEI Company, Eindhoven, The Netherlands) to remove any remnants of the lubricating oil and the debris entrapped between the flutes or in the fracture surface during flexural cyclic fatigue testing, and then allowed to dry. Two representative samples from each file system were randomly selected and photographed using SEM at magnifications of ×400 and ×1,500 for the cross-sectional views and ×300 and ×600 for the lateral views to verify the fracture mode.

Three teeth from each group (one tooth from each dog) were embedded in clear acrylic (Acrostone, Cairo, Egypt) into blocks and were cut longitudinally in the buccolingual direction into two sections through the center of the exposure site using mictotome (Technomotori, Italy). Sections were subjected to morphological observation under scanning electron microscopy (SEM) at 150× and 2500× magnification. Sections were subjected to elemental analysis Using SEM Model Quanta 250 FEG (Field Emission Gun) attached with EDAX Unit (Energy Dispersive analytical X-ray) (FEI company, Netherlands) with accelerating voltage (30) K.V. The amount of calcium and phosphorous within both the formed reparative dentin and the normal dentin were measured and were expressed as weight percentage at the area evaluated.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
