Five specialities where Dimple is already a known supplier. Pricing, grades and lead times tuned to how each of these teams actually buys.
Ultra-dry grades with water content under 50 ppm for non-aqueous electrolyte work. 3 to 5 day lead times beat Sigma's 10. Lot-level COA with trace metals.
Battery-grade inquiryReagent-grade PTA for PTAH, trichrome and TEM negative staining. Small quantities (5 g to 100 g) shipped fast. Typically 20 to 40 percent cheaper than Fisher.
Histology sample requestACS-grade Anhydrone for gas drying. Flexible pack sizes from 25 g to 25 kg. Karl Fischer water content and ICP-MS impurity profiles on every lot.
Analytical-grade quoteKeggin polyoxometalate with greater than 98 percent heteropolyacid content. Batch-consistent for PEM research. Multi-kilo pricing for scaling experiments.
Fuel-cell grade quoteDGFT-licenced dual-use export with full end-use documentation. IATA / UN 1489 packaging. Honest 3 to 4 week lead time including compliance checks.
