AOBIOUS offers all unit sizes in 'mg' quantity and allows customer to choose the exact quantity on need basis in order to avoid ordering extra material to waste. We only list the lowest unit price as $/mg on each product page. This leads to some confusion about our pricing policy to use one price to fit all. Actually we use price discount calculator to configure the price for any unit size. Here are two simple ways you can easily find right price discount to fit your need.
A1: Type in any number in quantity (mg) and then click 'Add to cart" button; the discounted price for any specific quantity (mg) will be shown in menu.
A2: You also can click "proceed to check out" and then click "+" and "-" sign to change the quantity or change quantity directly in box to see the price change.
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.
A: We would like to make customer to purchase research product at affordable price. We'll match and beat the product prices to all major competitors.
