Shipping Policy

Dispatch & Processing

Products marked as in stock are typically processed and dispatched within 1–2 business days following payment confirmation. Products marked “Available to order” are sourced specifically for you and show an estimated lead time on the product page, in your basket, and at checkout. That lead time applies before dispatch.

Mixed orders containing stocked and on-request products will normally be dispatched together when every item is ready. If you need the stocked items sooner, contact us before ordering so we can confirm whether a split shipment and any additional postage cost are possible.

Cold Chain & Packaging

To ensure the integrity of our sensitive research compounds, items that require temperature control are shipped in specialized insulated packaging with cold packs. This maintains stability during transit. We take the utmost care to ensure your research materials arrive in pristine condition.

Delivery Times (UK)

UK delivery is free on orders with a product subtotal over £50. Orders of £50 or less cost £5 for delivery. All orders use Royal Mail Tracked 48. Royal Mail aims to deliver within 2–3 working days after dispatch. This is a delivery aim, not a guaranteed 48-hour service. Processing time and any on-request product lead time are additional.

Delivery aims can vary for some postcode areas. See Royal Mail Tracked 48 service details for current information.

UK Delivery Only

Checkout currently accepts United Kingdom delivery addresses only. International shipping and expedited delivery options are not available at checkout.

Tracking & Missing Parcels

Once your order is dispatched, you will receive an email containing your tracking information. If your tracking indicates the package has been delivered but you have not received it, or if the package appears stuck in transit for an extended period, please contact our support team so we can investigate with the courier.
