Overview
This line covers tweezers built for reverse or self-closing action, where the jaws remain closed at rest and are opened by squeezing, as well as anti-capillary designs intended to reduce liquid wicking between the tips. Self-closing items are offered in styles #N4, #N5, and #N7 in antimagnetic stainless steel, with PTFE-coated versions also available for styles #N4 and #N5. Anti-capillary tweezers are offered as a variant of Style #5, in both plain antimagnetic stainless steel and PTFE-coated form. Both mechanisms are represented across the SPI-Swiss, SPI Supplies, and Dumont brands.
Self-Closing Mechanism
Self-closing (reverse action) tweezers are available in styles #N4, #N5, and #N7, with antimagnetic stainless steel or PTFE-coated construction, and Dumont also lists self-closing #N5 and #N7 versions in INOX stainless steel.
Anti-Capillary Design
The anti-capillary Style #5 tweezer is offered in antimagnetic stainless steel and in a PTFE-coated version with high-precision tips, intended to limit capillary drawing of fluids along the jaws.
