Vial Labels

1. Catalog number

This is a four digit number that identifies each product.

2. Unit size

The quantity of compound supplied in our vials is not weighed to the accuracy required for direct solution preparation unless specifically stated on the product datasheet. It is the responsibility of the individual researcher to accurately reweigh the compound in order to obtain solutions of defined concentration.

3. Product name

This will be the name by which the product is most commonly known.

4. Batch numbers

The batch number is the first number (in this case 4). The subsequent letter and number sequence (in this case B99046) are for internal use only.

5. Molecular weight

Product molecular weights are subject to batch variations. Customers should always use the molecular weight stated on the vial label and accompanying product datasheet. Variations between batches should make no difference to the basic pharmacological properties of the products.

For further information, please visit our molecular weight support page.

6. Storage conditions

Due to the novelty of many of our products, information concerning product stability has rarely been reported and in most cases we can only offer a general guide. When information is known we do our best to publish this on the vial labels and datasheets that accompany our products. Short periods of higher temperature, (>1 week) that may occur during shipping, will not significantly affect product life or efficacy.

7. Caution

All Tocris products are intended for laboratory use only. They must not be used for human, food, cosmetic, agricultural, domestic or any other use whatsoever.
