Hummer sputter coater

Manufactured by Anatech
Sourced in United States

The Hummer sputter coater is a lab equipment used for depositing thin films of materials onto various substrates. It utilizes a sputtering process to create these thin film coatings. The core function of the Hummer sputter coater is to provide a controlled environment for the sputtering deposition of materials.

Thermal, Structural, and Morphological Analysis of Polymer Composites

Check if the same lab product or an alternative is used in the 5 most similar protocols
The thermal behavior of MC, resin, physical mixture of MC and resin (2:1), and MR was determined with the aid of a DSC Analyzer (Shimadzu, TA-60WS, Japan). The temperature was increased to 250 °C at the rate of 15 °C min -1 .
The XRD patterns of MC, resin, MR, and physical mixture of MC and resin (2:1) were analyzed with an X-ray diffractometer (D/MAX-3C, Riguku Co., Japan) at a 56 kV voltage and 35 mA current. Samples were finely ground and irradiated with monochromatized Cu-Ka radiation after passing through Nickel filters and analyzed between 2 and 40° (2θ).
Morphologies of MC, resin, MR, and physical mixture of MC and resin were investigated by SEM. Dried samples were attached to specimen stubs with a double-sided copper tape and sputter coated with gold-palladium in the presence of argon gas using a Hummer sputter coater (Anatech Ltd., Denver, NC). The samples were recorded with a JEOL JSM-840 scanning electron microscope (JEOL USA Inc., Peabody, MA) at a 5 kV accelerating voltage and a probe current of 3 × 10 -11 A.

Visualizing TIPS Nanofibrous Scaffold Density

Check if the same lab product or an alternative is used in the 5 most similar protocols
In order to visualize the ability of TIPS to produce nanofibrous networks of three different densities, field emission scanning electron microscopy (FESEM) was used. The scaffolds were first sputter coated with gold/palladium using a hummer sputter coater (Anatech, Hayward, CA USA). The resulting scaffolds were then inserted into the FESEM (Strata™ 400 STEM DualBeam, FEI) and operated at an accelerating voltage of 10 kV and 12 μA.

Nanoscale Surface Roughness Analysis

Check if the same lab product or an alternative is used in the 5 most similar protocols
After gold was
sprayed using a HUMMER SputterCoater (Anatech Ltd., Springfield, VA,
USA), samples were observed by scanning electron microscopy (SEM,
FEI SIRION 200, Hillsboro, USA). Atomic force microscopy (AFM, Bioscope
II, Digital Instruments, USA) was used to scan the samples in the
tapping mode (1 × 1 μm2, 0.5 Hz). The results
were then analyzed using Nano Navi software (ver. 5.00, Japan) to
calculate the nanometer-scale surface roughness of the surface.

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.
