Q: How can I find the price of the product since the price does not change when I change the quantity on your product page?

AOBIOUS lists over 200 UNIT SIZES for every product in 'mg' quantity but cannot display them all in one page.

Q: How accurate does sample be weighed out?

A: Accurate measurement of sample is essential for getting valid and reproducible results. We calibrate our balance with readout 0.1 mg daily at room temperature 72F. All AOBIOUS sample unit under 50 mg quantity will be labeled with exact weight down to microgram level. EX: using 5.2 mg and not 5 mg etc. 

Customer can also instuct us to weigh out material at any specific quantity down to microgram level and we will use round off rules for 5 to decide final unit size of the order at mg level.

For instance, customer needs 4.3 mg exact quantity, we will weigh out exact 4.3 mg and count this as 4 mg unit size to calcuate final price. However if inquiring quantity is 4.7 mg exact we will weigh out the exact 4.7 mg quantity but will count this unit size as 5 mg.
