THE MIXTURE WAS FILTERED THROUGH A 0.22 UM FILTER AND 8 UL DROPS WERE MANUALLY DISPENSED UNDER PARAFFIN OIL USING A GILSON MICRO PIPPETTE. OVER 20 IDENTICAL DROPS WERE SET UP AND, WITHIN A WEEK, SINGLE CRYSTALS TYPICALLY MEASURING 0.5 X 0.4 X 0.3 MM WERE OBTAINED IN MOST OF THE DROPS. CRYSTALLISATION TOOK PLACE AT A TEMPERATURE OF 18 - 20 C., drops under paraffin oil, temperature 291K | ||||||||||||||||||||||||
