How to photograph vials for counting

  1. 1

    Show one visible layer

    Keep vial tops visible in a single tray. Remove packaging that covers the caps before photographing.

  2. 2

    Avoid reflections on the caps

    Use soft, even lighting. Bright reflections on metallic caps can obscure their outlines.

  3. 3

    Check rows and empty spaces

    Review the edges of the tray, gaps in rows and any marks placed on packaging rather than vials.

A top-down view makes the individual vial caps easier to distinguish.

When to count vials from a photo

Pharmaceutical plants and labs often handle vials by the tray: after filling, before and after freeze-drying, or when a batch moves to the next step. A photo taken from above gives a quick second check next to the usual count. Review the rows, tray edges and empty positions, then save the marked image with the total and date for your records.

Questions about counting vials

Should I photograph the caps or the sides?

Start with a straight-down view of the caps, like the example. Side views can hide vials behind the front row.

Will empty tray positions be counted?

They should not have a marker. Check empty positions after processing and remove any incorrect marks before using the total.

How many vials are in a tray or box?

There's no fixed number. It depends on the vial size, the tray or carton, and how full it is. Photograph the caps straight from above and check the markers to get the count for that tray. If a box has several layers, photograph and count each layer separately.
