Question 1

How do I verify the purity of KPV?

Accepted Answer

Batch BPL-KPV10-270726 reports 99.5%. The certificate can be read in full on the purity page, with its report number and date.

Question 2

Do I need to buy bacteriostatic water separately?

Accepted Answer

Not to start: every vial ships with 5 ml of bacteriostatic water included at no cost. If your work needs more volume, it is sold separately in a larger presentation.

Question 3

How much water do I add?

Accepted Answer

It depends on the volume you want each draw to be: the same vial can read 10 units or 100 depending on the water added. The site's reconstitution calculator converts your own numbers — we do not publish protocols or recommended amounts.

Question 4

Does it need a cold chain?

Accepted Answer

Not in transit: it ships lyophilised and dry, at room temperature. Once reconstituted, handling and storage are the responsibility of the laboratory using it.

Question 5

How long does shipping take?

Accepted Answer

3-5 business days with standard shipping, or 24-48 h with Express. Discreet packaging and tracking, anywhere in Mexico. With 3 items or more, standard shipping is free.

Question 6

Can I return it?

Accepted Answer

If the vial arrives sealed and unopened, yes, within 30 calendar days of delivery. An opened vial cannot go back into inventory, so there is no return in that case — what we always guarantee is identity and purity: if it does not match the COA for its batch, we replace it or refund it.
