Weighing by Difference

Step 2. If you want 0.1g to 0.2g of the material, then transfer about that much material from your weighed vial into an Erlenmeyer flask or whatever you want your material in. The empty flask is tared on a top load balance. When transferring, use one hand to hold the vial slightly tilted while the index finger taps the vial to allow a small amount of the material to come out.
