calcium chloride addition in dialysate bath

Hello:
Do any sites out there still add calcium chloride to their dialysate for calcium spikes? If so, what product are you guys using? The company that makes the 3g and 12g bottles of powder is discontinuing their sale of it as it has no DIN. The only other product available is the preloaded syringe but the company doesn't seem to have any data regarding stability with addition to dialysate but I am waiting for a reply still. If people could let me know ASAP that would be swell. Thanks!
