Ordering Department

To place an order 
Call 1-800-955-9525, Option 1, between the hours of 8:00 a.m. and 6:00 p.m. ET.  Alternatively, orders can be faxed to 781-861-6135.  IL is also able to accept orders via EDI.  If you are interested in enrolling in our EDI program, please contact us.

Orders received by 2:00 p.m. ET are shipped the same day via Two-day delivery service.  Hazardous materials are shipped according to transportation guidelines and therefore may not be shipped via Two-day service.  To avoid weekend delivery issues, and to ensure product integrity, refrigerated and temperature-sensitive products are shipped on Monday, Tuesday, and Wednesday only.  If you require an emergency shipment, please contact us for options.  

Reagents and supplies with shelf-life limitations are shipped with an expiration of no less than 90 days.  Controls and calibrators are shipped with an expiration date of no less than 30 days.  IL can sequester specific lots of controls and calibrators for up to 12 months, upon receipt of the associated purchase order. 

In the event of an order error, please notify us within 10 days of order receipt.  A return authorization number, allowing the return of the materials at no charge, will be issued.  Products must be returned unopened, in the original packaging.  If any markings have been made on the packaging, these products cannot be returned for credit.  Once we receive the authorized return, a credit will be issued (if applicable).

Please note: Hazardous material, refrigerated products, and date-sensitive products are not eligible for return.
