Terms and Conditions

Terms and Conditions – Updated 15 May 2024
These general Terms and Conditions are applicable to all of our sales.

  1. Offer and Order
    Orders may be submitted online, by email or by fax. Telephone orders must be confirmed by the customer in writing. Submission of your order to Syntezza Bioscience, Ltd. (hereinafter “Syntezza”) constitutes acceptance of these general conditions of sale and stands as a binding commitment by the customer to pay Syntezza the price for the products, applicable Value Added Tax (VAT) and any delivery charge that may apply. Syntezza shall not be obliged to accept any order. Once Syntezza has received and confirmed an order for a custom manufactured product, neither the scale of synthesis, technical specifications nor the relevant charges may be altered in retrospect.
  2. Price
    Unless stated otherwise, all Syntezza price quotations are in New Israel Sheqels, valid for 24-hours and do not include VAT. Catalog prices are subject to change without notice. Unless specified otherwise, prices listed on the Syntezza.com website, the websites of our Manufacturing Partners and our price quotations do not include VAT or shipping fees. Orders for unmodified 25 nmole DNA primers are supplied with no shipping fee. Orders for other products shall incur a shipping fee.
  3. Payment
    a. Payment should be made in NIS. Payment of each Syntezza invoice is due within thirty calendar days of the month in which the invoice is dated. Payments should mention the invoice reference number. Once the payment period has expired, the purchaser becomes automatically liable for the payment of interest for late payment of 12% per annum without formal notice of default being necessary.
  4. Should the creditworthiness of purchaser deteriorate, we reserve the right, even after the partial completion of an order, to require the buyer to provide such guarantees that we deem fit with respect to the satisfactory performance of the undertakings that have been entered into. A refusal to provide such guarantees gives us the right to cancel all or part of the order.
  5. All complaints regarding the invoiced amounts must reach us within 15 days of the invoice date, in the absence of which the invoice will be held to be accepted irrevocably and in its entirety.
  6. Delivery Times
    We are committed to manufacturing our products and delivering them to you with efficiency and expedience. Nevertheless, both Syntezza and our contract manufacturers subject the custom synthesized chemical products being made to rigorous quality control analyses. The nature of oligonucleotide and peptide synthesis is such that products synthesized with rigorous adherence to protocol occasionally fail to meet quality standards and need to be remade. Accordingly, the published times of delivery for products manufactured and distributed by Syntezza are best estimates and are not binding. We cannot be held liable for a delay in delivery and, in no case, can a delay in delivery give rise to the cancellation of the order.
  7. Usage
    a. All products manufactured and distributed by Syntezza are for the customer’s research purposes only. Resale of Syntezza products requires the express written consent of Syntezza. Syntezza products have not been approved for use in any clinical, diagnostic or therapeutic applications. Obtaining license or approval to use Syntezza products in proprietary applications or in any non-research (clinical) applications is the customer’s exclusive responsibility (see License Statements below).
  8. Syntezza will not be responsible or liable for any losses, costs, expenses or liability arising out of the unauthorized or unlicensed use of products manufactured or distributed by Syntezza. Purchasers of products manufactured or distributed by Syntezza shall indemnify and hold Syntezza harmless for any and all damages and/or liability, however characterized, related to the unauthorized or unlicensed use of such products.
  9. Approval
    The products are held to have been approved by purchaser by the elapse of fourteen calendar days after the delivery, except in the event of a precise and detailed protest sent to us by registered letter before the expiry of this period.  The approval will cover all patent defects, that is to say, all those defects that it is possible for the purchaser to discern at the time of the delivery and during the period of 14 calendar days following the delivery as a result of close and careful examination, in particular, those defects relating to the specifications and the operation of the products sold.
  10. Warranty and Limitation of Liability
    Custom oligonucleotides manufactured by Syntezza are guaranteed to meet or exceed our published specifications for quality and yield as measured under normal laboratory conditions. If our product fails to meet such specifications as identified by the purchaser prior to approval, Syntezza will promptly replace the product. All other warranties are hereby expressly disclaimed, including but not limited to, the implied warranties of merchantability and fitness for a particular purpose, and any warranty that the products, or the use of products, manufactured or distributed by Syntezza will not infringe the patents of one or more third-parties. Syntezza shall not be liable for any consequential damages. After delivery has been affected, we cannot assume any other liability other than that provided for by Article 6. In consequence, we cannot be held liable for any damage or interest arising from accident sustained by persons, damage to goods distinct from the sold products, loss of earnings or any other loss arising directly or indirectly from defects in the products.
  11. Reservation of Ownership
    The delivered products remain our property until the price has been paid in full, even in the event of the transformation or incorporation of the products into other goods.
  12. Rescission of the Sale
    We have the right to revoke the sale as of right and without formal notice of default, by notification of purchaser of our intention via email, in the event of non-performance by purchaser of one or other of his contractual undertakings, in particular if he is late in settling an invoice by more than 30 days, or if it should appear that he will not perform or that there is serious likelihood that he will not perform one or more of his main undertakings, even before he is required to perform such obligation. In the event of the rescission of the sale in application of the foregoing paragraph, purchaser will be liable for automatic damages and interest of 10% of the sale price.
  13. No Obligation Biosupport and Advice
    Our experienced scientific staff advises customers about technical applications and solutions in good faith, but without obligation. Our suggestions do not release purchasers from the requirement to check the suitability of our products for their intended purpose at their own risk and responsibility.
