Dimethyl Sulfoxide (DMSO) Resistance: Brady Material Ratings
Cryogenic cell banking, biological sample preservation, pharmaceutical synthesis. This engineering guide provides empirical laboratory test ratings for 9 Brady materials evaluated against Dimethyl Sulfoxide (DMSO) for print permanence and adhesive adhesion.
Standard Laboratory Test Protocol
Brady chemical immersion testing follows strict standardized procedures:
- Immersion Cycles: 5 cycles consisting of 10-minute soaks in Dimethyl Sulfoxide (DMSO) followed by 30-minute recovery periods at 22°C (72°F).
- Rub Test: Following final immersion, printed legends are rubbed with a cotton swab saturated in Dimethyl Sulfoxide (DMSO) for 10–20 double rubs under ~1 lb of downward force.
- Adhesive Inspection: Evaluated for edge lift, adhesive softening, ooze, or dissolution from stainless steel panels.
Thermal Ribbon Chemistry Importance
Face stocks like polyester and polyimide resist Dimethyl Sulfoxide (DMSO), but standard wax/resin ribbons will smear or dissolve instantly upon contact.

Frequently Asked Questions: Dimethyl Sulfoxide (DMSO) Resistance
Vinyl (PVC) polymers contain plasticizers that make the film pliable. Aggressive organic solvents like Dimethyl Sulfoxide (DMSO) extract plasticizers from the vinyl matrix, causing the film to swell, wrinkle, and soften the underlying acrylic adhesive. For heavy solvent contact, polyester (B-423) or polyimide (B-652) are recommended.
A wipe-down test simulates routine machine cleaning with a saturated rag for 10–20 rubs. An immersion test submerges the label directly into Dimethyl Sulfoxide (DMSO) for 5 cycles of 10 minutes. Many materials survive wipe-downs without degradation, but continuous total immersion requires specialized crosslinked resin ribbons and chemical-resistant face stocks.
