Frequently asked questions
We've collected answers to the questions we get most often. Don't see yours? Contact us →
Do you sell products through the website?
No. Björn Healthcare is an information catalog — we publish specifications, lab results, and pricing for B2B customers. Orders are fulfilled exclusively through partner channels (medical clinics, research centers, licensed distributors).
What is solvipurity.com?
Solvipurity is an independent analytical laboratory that verifies every one of our production batches. Enter the verification code from your product label on solvipurity.com to see the full HPLC-MS report for that specific batch — independent of our shop.
How does the batch lookup work?
Every product has a unique batch number in the format BJRN-20XXXXX printed on the package. Enter it on the "Verify batch" page to confirm expiry date, lab testing date, and product identity. This is standard pharmaceutical GMP traceability.
How do I read an HPLC-MS report?
HPLC (High Performance Liquid Chromatography) shows the active substance peak, its area, and profiles of potential impurities. MS (Mass Spectrometry) confirms chemical identity. A purity value above 99% means the active substance makes up over 99% of the sample mass.
What does "for research use only" mean?
Our products are sold exclusively for research, analytical, and control purposes. They are not intended for human consumption or for clinical applications without medical supervision. Responsibility for use lies with the buyer.
How long does delivery take?
Deliveries are completed within 1–5 business days within the EU. In-stock products ship the next business day after order confirmation; custom orders (non-standard doses, large volumes) ship within 2 weeks.
Do you offer wholesale pricing?
Yes. We offer individual rates to B2B clients (clinics, laboratories, research centers) for orders above a specified volume. Contact us through the contact form — we'll propose terms.
Why does the difference between 99% and 99.8% purity matter?
In a research environment, a 0.8 percentage point difference represents an order of magnitude higher potential impurity content — which can affect experimental results, dosing, and safety profiles. We set our floor at 99.5% and publish exact values for every batch.
