Testing, ordering and shipping
Which workflows require specialized equipment or qualified facilities?
Mass analysis requires a suitable mass spectrometer; chromatographic analysis requires an HPLC or LC-MS system. Endotoxin and growth-detection work also require qualified facilities, trained personnel, controls, and a validated sample-appropriate method. We sell selected supplies, not a complete validated laboratory process.
How are kit prices set?
Each kit costs 10% less than buying its items separately. The saving is shown on every kit. A kit is not a validated method.
Which column should I choose?
Column selection depends on the instrument, analyte, method, pressure limits, selectivity, and validation requirements. The listed dimensions are common starting points, not a guarantee of resolution or method suitability. Contact support with the instrument and method requirements before ordering.
Do you sell solvents, acids or stains?
No. We do not sell flammable, corrosive or toxic chemicals — no acetonitrile, TFA, formic acid or ninhydrin stain. Order those from a chemical distributor that is set up for hazardous-materials shipping. Everything in our catalog ships by standard services.
How fast do orders ship?
We confirm the dispatch date on your invoice before you pay. Orders over $300 ship free.
Can I return something?
Unopened instruments and consumables can be returned within 30 days; email support for return instructions first. Reagents, media and opened consumables cannot be returned for safety and integrity reasons. If anything arrives damaged, defective or incorrect, tell us within 7 days and we will replace it or refund it.
Do you accept purchase orders?
Universities, companies and contract labs can apply for a lab account with invoicing. Accounts and any credit terms require approval, and approval does not change a product's labeled intended use, processor eligibility or shipping restrictions.
Are the reagents for diagnostic use?
No product should be used outside its manufacturer-labeled intended use. Unless a product page states and documents a different status, reagents are for laboratory research use only and are not for diagnostic procedures or patient-use decisions.
