Lab Glove Selection Guide - Harvard University- nitrile gloves breakthrough time ,Breakthrough Time for the glove materials. Breakthrough times are usually determined under conditions of constant contact under pressure and may underestimate performance in laboratories. Where manufacturers provide breakthrough times specifically based on intermittent contact testing, these values are used. The gloves included in the Glove ...Guide to Chemical-Resistant Best Gloves1. Breakthrough Detection Time (BTT): the time in minutes after initial exposure of a chemical to the outer surface of the glove material to the time it can first be detected on the inside of glove. BTTs reported are normalized to a permeation rate of 0.1 µg/cm2/min. All BTTs meet this requirement except those analyzed by pH or conductivity.

Breakthrough time is time it takes a chemical to permeate completely through the material. It is determined by applying the chemical on the glove exterior and measuring the time it takes to detect the chemical on the inside surface. The sensitivity of the analytical instruments used in these measurements influence when a chemical is first detected.
