Terms & Conditions

1. Acceptance and scope

These Terms & Conditions (“Terms”) govern access to and use of this website, member accounts, product information, documentation requests, communications, and inquiries operated by Stack Research LLC, a Wyoming limited liability company (“Stack Research,” “we,” “us,” or “our”). By using the site, you agree to these Terms. If you do not agree, do not use the site. A separate affirmative acceptance is required for the Research Access and Use Agreement.

2. Eligibility and organizational authority

The research-access portions of the site are intended only for individuals age 21 or older conducting lawful in-vitro laboratory or analytical research in a professional capacity. A member may identify as a researcher without entering an organization or business. If you do provide an organization, you represent that the information is accurate and that you have authority to act for it. Email verification is an account-security procedure and not proof of identity, licensure, authority, end use, or legal permission.

3. Research-use restrictions

Product information, documents, samples, and any materials discussed through Stack Research are not intended for use in or on humans or animals, self-experimentation, diagnosis, treatment, disease prevention, compounding for humans or animals, or any consumer, clinical, food, drug, cosmetic, medical-device, or veterinary purpose. The Research Agreement & Waiver contains the controlling access, prohibited-use, anti-diversion, assumption-of-risk, and electronic-signature terms and is incorporated into these Terms for members who accept it.

4. No medical or regulatory advice

The site does not provide medical, veterinary, pharmacy, toxicology, legal, or regulatory advice. Stack Research does not provide dosing, administration, reconstitution for human or animal use, clinical protocols, diagnoses, prescriptions, treatment recommendations, or assurances that a material or activity is approved, safe, effective, lawful, or suitable.

5. Ordering, payment, promotions, and transaction review

Product listings and prices are invitations to submit an order, not promises to supply. Checkout requires a verified member account and acceptance of the current Research Access and Use Agreement. An order remains subject to successful payment authorization, product and destination eligibility, and any required fraud or compliance review. Stack Research may request supporting information, restrict quantities or destinations, correct an error, or reject or cancel an order before acceptance. A support message, documentation request, quotation, or other correspondence does not by itself create an order. Accepted payment methods, currency, timing of charges, the statement descriptor, and refund routing are described in the Payment & Billing Policy, which is incorporated into these Terms.

Payment methods depend on the order, device, delivery address, browser, wallet, and current provider availability. The final checkout screen controls. For an order routed through the SellAbroad card gateway, the checkout, order record, and customer email identify SELLABROAD as the expected statement descriptor. A card network or issuing bank may shorten, supplement, or display that text differently. Other payment routes may use different records.

Promotion codes, automatic volume pricing, and Stack Builder savings remain subject to their displayed eligibility, usage limits, and expiration terms. Eligible percentage savings are compared for each item and do not compound. The stronger eligible percentage code or automatic item-level savings applies. Shipping thresholds are calculated from discounted merchandise and exclude shipping, fees, and taxes.

6. Orders, returns, and customer responsibility

A sale exists only when Stack Research accepts it through an authorized order process and all stated conditions are satisfied. Review the product, configuration, quantity, promotion, delivery address, recipient, service level, price actually charged, tax, fees, and total before submitting an order. Stack Research may correct product or pricing errors, request verification, limit quantity or destination, or reject or cancel a transaction before acceptance.

Opened research products are final sale and cannot be returned. A factory-sealed, unused, unaltered product may qualify for return only when the customer requests authorization within 14 calendar days after delivery and follows the posted Returns & Refunds Policy. The Shipping Policy also forms part of every accepted order. These policies preserve a separate review and remedy process for timely, documented claims involving carrier loss, transit damage, an incorrect or missing item, or a supported product-specific packaging or temperature failure. No oral statement authorizes a return, refund, prohibited use, or exception to these terms.

7. Product, receipt, and documentation limitations

Names, descriptions, configurations, images, certificates, analytical reports, purity figures, safety information, availability, and other content may be supplier-provided, provisional, lot- or sample-specific, method-dependent, incomplete, superseded, or unavailable. A record applies only to what it expressly identifies. You must independently evaluate identity, quality, hazards, methods, controls, regulatory status, and suitability and must not rely on the site as the sole basis for a research, safety, purchasing, or compliance decision.

After delivery, the customer must inspect the package promptly, preserve relevant labels and records, and store and handle the material under the product-specific terms provided for the accepted order. Opening the outer shipping parcel does not by itself make a product ineligible, but the product packaging, closure, and tamper evidence must remain intact for an unopened return. Any material physically returned under written authorization is quarantined and never restocked, resold, or shipped to another customer.

8. Accounts and security

You must provide accurate information, maintain control of your verified email and authenticated devices, prevent unauthorized use, and promptly notify Stack Research if access or an agreement record may be compromised. You may not impersonate another person or organization, share an account without authority, probe or bypass access controls, scrape protected content, introduce malicious code, disrupt the site, or use the site to facilitate unlawful conduct.

9. Suspension and changes to the service

Stack Research may restrict, suspend, or terminate access, refuse an inquiry, preserve relevant records, or modify or discontinue site features when reasonably necessary for security, suspected misuse, legal compliance, operational changes, or breach of these Terms. We do not guarantee that the site or any particular product record will remain available.

10. Intellectual property and permitted use

The site, design, logos, text, software, and original materials are owned by or licensed to Stack Research and protected by applicable law. Stack Research grants you a limited, revocable, nonexclusive, nontransferable right to use the site for its intended lawful business purpose. You may retain an agreement or policy for your records. You may not reproduce, republish, sell, modify, remove notices from, create derivative works from, or commercially exploit protected site content without written permission.

11. Third-party services and links

The site and any accepted transaction may rely on hosting, security, email, payment, fraud-prevention, supplier, fulfillment, carrier, insurance, document, analytics, customer-support, or other providers. Those parties may apply their own terms and privacy practices. A link or integration does not constitute an endorsement, and Stack Research is not responsible for third-party content or services outside its control. Nothing in this section eliminates a remedy expressly provided by the accepted order terms or applicable law.

12. Privacy and communications

Personal information is handled as described in the Privacy Policy. Verification codes, agreement records, account-security notices, order confirmations, tracking and delivery updates, recall or safety notices, claim communications, and direct support replies are transactional or service messages—not marketing. Marketing is off by default, requires a separate affirmative choice, and can be withdrawn without stopping necessary service messages. You are responsible for keeping your email current.

13. Disclaimer of warranties

TO THE MAXIMUM EXTENT PERMITTED BY LAW, THE SITE, ACCOUNTS, CONTENT, PRODUCTS, DOCUMENTS, AND COMMUNICATIONS ARE PROVIDED “AS IS” AND “AS AVAILABLE.” STACK RESEARCH DISCLAIMS EXPRESS, IMPLIED, AND STATUTORY WARRANTIES, INCLUDING ACCURACY, COMPLETENESS, NON-INFRINGEMENT, MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, SECURITY, AVAILABILITY, AND RESULTS. RIGHTS THAT CANNOT LAWFULLY BE DISCLAIMED ARE NOT DISCLAIMED.

14. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, STACK RESEARCH AND ITS MEMBERS, MANAGERS, PERSONNEL, CONTRACTORS, SUPPLIERS, AND AGENTS WILL NOT BE LIABLE FOR INDIRECT, INCIDENTAL, SPECIAL, EXEMPLARY, PUNITIVE, OR CONSEQUENTIAL DAMAGES; LOST PROFITS, DATA, RESEARCH, BUSINESS, OR OPPORTUNITY; OR DAMAGES ARISING FROM UNAUTHORIZED, PROHIBITED, OR UNLAWFUL USE. THEIR TOTAL AGGREGATE LIABILITY ARISING FROM THE SITE OR THESE TERMS WILL NOT EXCEED THE GREATER OF ONE HUNDRED U.S. DOLLARS OR THE AMOUNT PAID DIRECTLY TO STACK RESEARCH FOR THE TRANSACTION GIVING RISE TO THE CLAIM DURING THE PRECEDING TWELVE MONTHS. THIS DOES NOT LIMIT LIABILITY THAT LAW PROHIBITS LIMITING.

15. Indemnification

To the maximum extent permitted by law, you and any organization you validly bind will defend, indemnify, and hold harmless Stack Research and its members, managers, personnel, contractors, suppliers, and agents from third-party claims, government actions, losses, liabilities, penalties, judgments, costs, and reasonable attorneys’ fees arising from inaccurate information, unauthorized account activity caused by your failure to secure access, breach of these Terms, violation of law, infringement, prohibited use, diversion, or representations you make to others. This obligation does not apply to the extent a final nonappealable judgment determines that the matter resulted from the indemnified party’s gross negligence, willful misconduct, or fraud.

16. Governing law and venue

These Terms are governed by Wyoming law, without regard to conflict-of-law rules, and applicable federal law. To the extent permitted by law, each party consents to exclusive personal jurisdiction and venue in a state court of competent jurisdiction in Wyoming in which venue is proper under applicable law or, when federal subject-matter jurisdiction exists, the United States District Court for the District of Wyoming, and waives objections to those forums based on personal jurisdiction or forum non conveniens. Rights, remedies, jurisdictions, and forums that cannot lawfully be waived, and government authority, are preserved.

17. Changes and general provisions

We may revise these Terms prospectively by posting an updated version and effective date. Material changes may also be communicated through the site or verified email. If a provision is unenforceable, it will be enforced to the maximum lawful extent and the remainder will continue. Delay in enforcement is not a waiver. You may not assign these Terms without written consent; Stack Research may assign them in connection with a financing, reorganization, merger, or transfer of business or assets. These Terms, the Research Access and Use Agreement where accepted, the Privacy Policy, and applicable transaction terms form the entire agreement on their respective subjects.
