A good rule of thumb is: 1  for difficult separations (Î´CV â¤ 1) use up to 100 g (~200 mL) of silica gel per gram of compound to be purified (1% load) 2  for normal separations (1 â¤ Î´CV â¤ 5) use from 20 to 90 g (~40-180 mL) of silica gel per gram of compound to be purified (2-9% load)
Typical costs: 1  According to the Academy of Managed Care Pharmacy , insulin pumps cost between $4,500 and $6,500 for individuals without insurance. The price varies depending upon the features, brand and size of the pump. 2  Some insurance plans will cover the cost of the pump.
So if you test minimum 4x daily... That's 120.00 monthly. Insulin (humalog) the kind I use is 122.00 a bottle. I use 2.5-3 bottles a month. I am on an insulin pump. Without insurance- the medtronic insulin pump is over 7000.00 dollars. The supplies I use with my pump are 200.00(ish) a month for each type (infusion set and reservoir). It's been a long time since I've used syringes so I don't know how much they are. I'm positive it's not over 20-30 dollars.
