You can review or print the instructions [PDF - 647 kB] for the Sigma website.


Sigma offers special pricing based on an agreement established with the Dalhousie Procurement Department. All university pricing is available in real time when using your account. A shopping list can be created to list your regular purchased items.


All in-stock items received by 4 p.m. will be delivered within 24-48 hours. Sigma shows live inventory at the time you place your order, so you will know if an item is on backorder. To reduce overall costs associated with the processing of orders, discretion should be used for order quantities and frequency. Larger orders placed less frequently will assist in the control of operating costs and ultimately reduce freight costs for campus users.

Special orders

Should you have a special need that cannot be met by standard product offering, please contact the Procurement Department. Items not found on Sigma are considered to be "non-stock". These specials or "non-stock" orders may be non-returnable or subject to restocking charges—please order with caution.

Packing slips

A packing slip will accompany each order. Confirm that the goods you have received are correct. Any discrepancies should be reported immediately to Sigma's Customer Service Department. Do not forward invoices to accounts payable. These are for your record only.

Back orders

Any back orders will be identified on the order confirmations but not the packing slips.  These items do not need to be reordered—delivery will follow when received by the supplier. The status of any order may be viewed on your account.


The goal for both Dalhousie and Sigma is to minimize operating costs. Returns increase costs for both parties. If you are uncertain whether you are making the correct selection during the order placement process, please contact the Customer Service Department. They will be happy to clarify the product selection or unit of measure required. If you have any doubt, a telephone call before your order placement will help reduce order errors significantly.

A credit will be issued, less a 20 per cent restocking fee, for regular items that are returned within 30 days of receipt of the goods. Temperature-controlled items cannot be returned.  All returned merchandise must be sent back in reasonable condition, complete with the original packaging and all instruction materials.   

Prior to returning goods for credit, authorization must be received from the Customer Service Department. Please provide the following information:

  • packing list number found at the top of each packing slip
  • product number for item being returned
  • quantity
  • reason for return

The customer service staff will generate the necessary paperwork that the driver must have prior to taking back any returns. Returns will be picked within 48 hours.
