                                        Essential Terms of Sale

                                        By completing your purchase, you acknowledge and agree to the following professional laboratory supply terms:

                                        • Professional Use Only: These products are intended for laboratory or industrial use by qualified professionals. The buyer assumes all liability for safe handling and regulatory compliance.
                                        • 48-Hour Damage Reporting: Due to the fragile nature of lab equipment, shipping damages must be reported with photographic evidence within 48 hours of delivery.
                                        • Direct Fulfillment: Items ship directly from our US-based manufacturing partners (Doba/TopDawg). Delivery windows are estimates and not guaranteed arrival dates.
                                        • Restocking Fees: Non-defective returns (if approved) are subject to a 15% restocking fee. Items must be unopened and in original factory packaging.
                                        • Final Sale: To maintain the safety and integrity of lab supplies, we do not accept returns for "change of mind" or buyer's remorse.

                                        For full legal details, please refer to our main Terms of Service and Refund Policy pages.
