SPI Supplies Calibrated Asbestos Index Grids, Regular 200 Mesh Copper AHERA, Pack of 1000 Grids
55% open area
30 µm bar width
95 µm grid square
Each package includes:
1000 Asbestos Index Grids (10 vials of 100, you select the type - all 200 mesh copper)
AHERA-Required Documentation of Open Area Calibration
Not Everyone Needs "Calibrated" Grids:
Everyone doing asbestos TEM work does not need to purchase (or use) "calibrated" grids; it is something needed primarily by those doing work that must confirm to the AHERA specifications. For all others, these same grids are available, for a much lower price, uncalibrated.
Trained technicians in our own laboratories use the fast and accurate SPI-QuantII™ Image Analysis System to measure 20 grid openings on each of 20 randomly selected grids (two from each vial of 100).
Each package of 1000 grids is inspected to assure "zero" defects, and comes with documented results from the calibration of these 400 grid squares. This is provided as an average measurement with standard deviations in a format suitable for inclusion in your AHERA Quality Control notebook.
It's easy! Let your lab technicians concentrate on boosting productivity and shortening turn-around times. Let SPI handle the time-consuming task of calibrating grids to meet AHERA documentation requirements! (Contact email@example.com)
