Sample Preparation Equipment

Over the past 20+ years, the ISN has established in Technology Square a facility containing cutting-edge research instrumentation. These instruments are available to those participating in ISN research and also to rest of the MIT community.

Some of the ISN's advanced instrumentation requires that samples be specially prepared for testing in analysis equipment or imaging in microscopy equipment. 

See the list below for details on each available piece of sample preparation equipment.

Please stay tuned for further updates to this page, including additional pieces of equipment on which the ISN offers training.

Cross Section/Ion Beam Polisher
JEOL SM-09010 Cross-Section Polisher

The cross-section polisher makes a cross-section perpendicular to the surface of a specimen suitable for the measurement of multi-layered structures.

The instrument can prepare a cross-sections from soft materials, including copper, aluminum, gold, solder, and polymers; hard materials such as ceramic and glass; and composites of these materials. Equipped with an argon ion beam, the ISN's SM-09010 is generally used to prepare cross-sections of materials such as fibers or multi-layer films. The primary benefit of this instrument for ISN users is its ability to cut through dissimilar materials cleanly to provide a high quality flat surface for SEM imaging.

Cross-sections prepared are suitable for EDS, WDS, Auger, and EBSD (Electron Back Scatter Diffraction) analysis, and for observation and measurement of multi-layered structures.

The instrument preserves structures that a conventional mechanical polish would destroy, such as voids in a bonded interface between gold wire and bonding pad. Adhesion between plated layers, or between solder and metal, can be observed and analyzed accurately. Cross-sections are also suitable for analysis of precipitates.

Damage to a specimen during polishing is much less compared to FIB preparation due to the use of an argon ion beam. The SM-09010 can make a large cross-section surface up to 1mm in width.

Lyophilizer
Labconco FreeZone Benchtop Freeze Dryer Model 7934000

Note: Users must supply their own flasks.

Used for the preservation of samples, freeze drying is the process of removing water from frozen materials by converting the frozen water directly into its vapor without the intermediate formation of liquid water.

The basis for this sublimation process involves the absorption of heat by the frozen sample in order to vaporize the ice; the use of a vacuum pump to enhance the removal of water vapor from the surface of the sample; the transfer of water vapor to a collector; and the removal of heat by the collector in order to condense the water vapor. In essence, the freeze dry process is a balance between the heat absorbed by the sample to vaporize the ice and the heat removed from the collector to convert the water vapor into ice.

The Labconco FreeZone Plus 6 Liter Cascade Console Freeze Dry System is designed for light to moderate loads of low eutectic point samples. It removes a maximum of 4.1 liters of water in 24 hours with a collector temperature of -84° C (-119° F) and has an ice holding capacity of 6 L.

Slide Stainers (Layer-by-Layer Deposition)
Microm DS-50 Slide Stainer (x4)

Microm DS-50 Slide Stainers provide a computer-controlled system for the automated cyclical dipping of substrates. They are typically used for layer-by-layer (LbL) deposition applications. The LbL technique is used to build multi-layer films, such as those used in drug delivery mechanisms (time-controlled delivery) and for sensing elements (biochemical sensing structures) that change their properties when they come into contact with the analyte material of interest. A robotic arm dips the substrate into a positive polymer solution that adheres to the substrate, which is then dipped into a clean water or solvent bath, then into to a negative polymer solution which will adhere to the previously deposited positive layer. This is repeated over a fixed amount of time to produces multiple layers.

The ISN currently has 4 Microm DS-50 Slide Stainers.

Spin Coaters
Cookson Electronic Equipment SCS G3P-8 (x2)

Spin coaters are used in production of thin films.

A typical process involves depositing a small amount of fluid resin onto the center of a substrate and then spinning the substrate at a high speed, usually around 3000rpm. Centripetal acceleration causes the resin to spread to and beyond the edge of the substrate, leaving a thin film of resin on the surface.
