Electron Microscopy Sciences MXS Calibration Standard MXS 702CE for SEM, Pin 700 nm, 700 nm Spacing
EMS offers a series of calibration standards with one and two dimension calibrated patterns. These standards are created utilizing holographic interference of a particular laser frequency. They are typically accurate to <1% across the entire surface of the standard. These reference standards are remarkably durable under typical operating conditions. The surface contamination behavior is also very good. There are no better sub-micron reference standard available in this price range.

Electron Microscopy Sciences Brain Matrix Adult Monkey Cynomogus, Coronal cerebrum
RBM allow the investigator to slice either coronal (perpendicular to center line) or sagittal (parallel to center line) sections through the brain at intervals as small as 1mm. All RBM's are identical and durable to insure reproducible sections in the day-to-day, year-to-year, or on a between laboratory basis.
Constructed from high grade zinc to allow for rapid temperature equilibration, easy cleaning, and sterilization. The matrices are designed to accommodate the brains of rodents placed ventral side up. The channels are precisely cut at 1 mm intervals and 0.3 mm wide.
Type: Coronal cerebrum
