Contact and support

How can we help?

Written answers on products, prices, orders, shipping, and lot results. We reply within 1–2 business days.

Do not send confidential research details, or personal information we do not need to find your order.

Find the right support

A little context helps us answer faster.

Orders and payment

Order number or payment reference

For invoice, e-Transfer reconciliation, cancellation or order-status questions.

Shipping

Order number and tracking reference

For dispatch, carrier or delivery-record questions.

Lot results

Lot identifier

For a published batch-results or lot-page question.

Testing pre-approval

From your account, not by email

Request verification pre-approval while signed in. That is how we confirm the vial, the laboratory, and the scope against the order. Email is the slower route to the same decision.

Formal contacts

Business and privacy correspondence.

No public telephone number is offered. Written support allows requests and responses to be retained with the relevant record.
