More rigorous calibrated balance techniques, with SI traceability have been pioneered, mostly by National Metrology Institutes (NMIs), but their complexity, expense, and time-consuming operation make them an out-of-reach technique for most AFM researchers. The reference cantilevers represented by NIST SRM 3461 are an accurate and precise force calibration artifact for use in the field.<\/p>\n<p>SRM 3461 is a silicon microfabricated device containing seven cantilevers of carrying length and stiffness is used for validating methods for determining the stiffness of atomic force microscope (AFM) cantilevers as well as directly calibrating AFM test cantilevers using the reference cantilever method.<\/p>\n<p>A unit of SRM 3461 consists of one silicon microfabricated device approximately 1.6 mm by 3.0 mm containing an array of seven (7) uniform, rectangular cantilevers of varying length and stiffness at the end. Each cantilever is nominally 50 \u03bcm wide and 1.45 \u03bcm thick with lengths of 300 \u03bcm to 600 \u03bcm in steps of 50 \u03bcm. The device comes adhered to a polydimethylsiloxane (PDMS) gel film in a protective antistatic enclosure with a removable top. It can be used as-is by temporarily removing the top or could be carefully transferred to an appropriate alternative holder. SRM 3461 was microfabricated, packaged, and calibrated in a clean room environment to minimize exposure to dust, debris, and contaminants. The packaging provided is intended to protect the device during shipping and storage in non-cleanroom laboratory environments. The device should be stored at room temperature (20 \u00b0C \u00b1 5 \u00b0C) when not in use.<\/p>\n<div class=\"article-main__more p-4\">\n                                                                                        <strong>More information:<\/strong><br \/>\n                                                Richard S Gates, Certification of Standard Reference Material\u00ae 3461 Reference Cantilevers for AFM Spring Constant Calibration, <i>NIST Special Publication<\/i> (2022).  <a rel=\"nofollow noopener\" target=\"_blank\" data-doi=\"1\" href=\"https:\/\/dx.doi.org\/10.6028\/NIST.SP.260-227\">DOI: 10.6028\/NIST.SP.260-227<\/a><\/p>\n<\/div>\n<div class=\"d-inline-block text-medium mt-4\">\n<p>\n                                                    Provided by<br \/>\n                                                                                                            National Institute of Standards and Technology<br \/>\n                                                                                                                <a rel=\"nofollow noopener\" target=\"_blank\" class=\"icon_open\" href=\"http:\/\/www.nist.gov\/index.html\"><br \/>\n                                                            <svg><use href=\"https:\/\/phys.b-cdn.net\/tmpl\/v6\/img\/svg\/sprite.svg#icon_open\" x=\"0\" y=\"0\"\/><\/svg><\/a><\/p><\/div>\n<p class=\"article-main__note mt-4\">\n                                                  <i>This story is republished courtesy of NIST.
