I have just been using 1/4 tsp for stuff, but when 300mg is a serving +/- 50 is quite abit of sway there.
What do you think of the HP-100x?
HP-100X Pocket Scale By: My Weigh
I need to measure out powders...llike 300mg +/- 10mg would be safe enough. I'd also like it to go high enough like 70g to measure out malto/WMS/dextrose etc.
What do you guys use?
myweigh mx-50's are good- we use them for a variety of applications, and it has a resolution of .01 grams- but it only goes up the 50.00 grams....
ecolab (sartorius group) good scale for 1 gram up to 4 kg- very, very accurate for mid-range apps
any sartorius analytical balance- they have scales that will measure all the way down to mcgs; not cheap
The above can also be easily calibrated as well- and are not very sensitive to vibration, etc.
Always remember to cut any air source in the room off when you are weighing, checking, or calibrating a scale- may skew the measurement or balance
always weigh, check, or calibrate on a level surface- a pocket level will suffice
check out USP <2091> (determining weight for dietary supplements) for weighing methods- they have some good insights
check out USP <616> as well- the first part will give you a way to determine bulk density very easily- this will help you figure out how much powder can go into any given capsule
