Hi Yibin, I cannot tell the actual scale of your crystals but judging by the curve of the drop outline, these crystals look to be plenty big enough to mount in a loop to stick in the beam and test diffraction. If indeed they are too small to mount a single crystal, and you are mainly

Hi Yibin, MiTeGen offers different loops that make it easier to pick really tiny crystals which can be diffracted at the synchrotron. If you would like to optimize small needles or rod shaped crystals, you may try an additive screen. You may also try to lower the rate of crystal growth.

I like using Izit dye from Hampton ( http://hamptonresearch.com/product_detail.aspx?cid=4sid=41pid=33) to check if crystals are protein or salt. If the crystals are protein, the dye should absorb rather readily into the crystals and turn them blue, while the rest of the drop will eventually turn
