Powder-Free Nitrile Gloves, Box of 100

Ansell TouchNTuff 92-600 powder-free nitrile gloves are 0.12 mm disposable gloves with EN ISO 374-1 Type B marking (the European standard for chemical protective gloves). They provide a barrier in both directions, and both are important: they protect the hand from splashes and protect the work from the hand — from the grease, salts, and sweat of the skin. They are changed as soon as they are contaminated, not at the end of the day.

Applications

• Work with aqueous, chelating, and surfactant cleaning systems
• Handling metal, gilding, photography, and polished surfaces, where chloride from sweat causes the most damage
• Preparation of gels, solutions, and emulsions at the bench
• Classroom and practical work, where consumption is high and gloves are frequently replaced

Features

• Powder-free. Powder from the inner surface transfers to the work surface. This is the primary criterion for conservation gloves, not a comfort detail
• Nitrile, not latex. Natural latex contains sensitizing proteins and can leave residue on objects; nitrile is chemically stable and does not
• Single-use. Protection is renewed by changing the glove, not by washing it
• Declared thickness: 0.12 mm. A glove without declared thickness cannot be evaluated
• EN ISO 374-1 Type B: Type B certifies a breakthrough time of at least 30 minutes against three of the substances on the standard's list. The manufacturer declares which ones

What you need to know before using them with solvent

This is the part of this product sheet that determines the purchase, and we wrote it entirely because keeping quiet would be the problem.

A disposable nitrile glove is a barrier against splashes and brief contact. It is not an immersion glove or for sustained work with solvents. And the information a professional needs to know, because it is not intuitive, is this: the glove may remain visually intact—without swelling, without becoming sticky—yet be allowing the solvent to pass through to the skin. The manufacturer itself states: permeation through the film occurs without visible pores or openings and the permeated material may appear unaltered to the naked eye. Visual inspection does not detect failure. The rule that does work is one of time and change: new glove to start, change as soon as there is contact, and remove at the end of the task.

And with which families it makes sense. These are the ratings for nitrile as a material in the selection guide of the American Institute for Conservation, the industry reference:

• White spirit, mineral spirits, petroleum ether, and isopropanol: very good, over 8 hours. This is the legitimate use of nitrile in restoration
• Ethanol: acceptable, 1 to 4 hours
• Acetone, toluene, xylene, methyl ethyl ketone, ethyl acetate, and tetrahydrofuran: not recommended, less than one hour

These are ratings for nitrile as a material, measured on high-thickness reusable gloves; they are not a test on this specific reference. And they must be read with two corrections that no catalog table includes: a mixture behaves like its worst component, not like the average — adding a hydrocarbon to a ketone can reduce breakthrough time from hours to minutes — and tables are measured at 21 °C while the hand is at 35 °C, where times decrease. Thickness also does not change the conclusion: it does not change WHAT the glove resists, it changes HOW LONG it resists.

For acetone, ketones, and aromatics in sustained work, the material is different: butyl, multi-layer laminate, or neoprene. They do not replace disposable gloves, they coexist with them. And for acetone, the measure that truly protects is not the glove: it is local extraction or a fume hood.

An important improvement if you work with silver or gilding

There are nitrile gloves without sulfur accelerators. The sulfur in vulcanization accelerators can react and tarnish silver, and the Canadian Conservation Institute itself warns that some nitriles can do this. If your work involves silver, metallic thread, or gilding, that version is the one you need: write to us and we will provide it.
