A dangerous lab fire that didn't happen
MALLINCKRODT SPECTROPHOTOMETRIC SOLVENTS COME IN NEW "BOUNCING GLASS" SAFETY BOTTLES For your protection, we've put our more flammable SpectrARG solvents in new, PVC-coatcd glass bottles. These bottles arc extremely hard to break. Usually, they'll bounce right off your floor, preventing breakage and flash fires. You might as well have this extra safety, because you'll also do your best spectrophotometric work with SpectrAR solvents. Mallinckrodt provides a booklet of permanent UV-VIS-NIR and IR absorbancc charts on every solvent. You can swear by these curves. Product uniformity is controlled by spectrophotometric and GLC analysis. This assures that each lot precisely matches the NIR and IR reference curves and exceeds the purity required to match the UV-VIS curve. Typtcal SpectrAR abtorbanc* chart
