18O- Water
What are applications of Oxygen-18 Water (H₂¹⁸O)?
Oxygen-18 Water, a highly enriched stable isotope of water, has several critical scientific and medical uses. It is primarily used as a precursor in nuclear medicine, a tracer in life sciences, and a reference standard in environmental research.
Medical (PET Imaging): Oxygen-18 Water is the essential starting material (target material) for the production of ¹⁸F-FDG in medical cyclotrons. This radiopharmaceutical is widely used in Positron Emission Tomography (PET) scans for tumor and brain imaging.
Scientific Research (Tracers): It is used as a stable isotope tracer in metabolic studies, particularly the Doubly Labeled Water (DLW) method to measure human energy expenditure and body composition.
Pharmaceutical & Chemistry: Used as a precursor for synthesizing ¹⁸O-labeled compounds and for tracing reaction mechanisms in drug development.
Environmental Science: Utilized in paleoclimatology and hydrology as an isotopic tracer to study ancient water cycles and track climate change.
Why Choose Our Oxygen-18 Water?
Qualified & Approved by Leading Institutions
We are already a trusted supplier to global companies and research institutes. Our Oxygen-18 Water has passed their strict quality, isotopic enrichment, and reliability tests. New customers benefit from this proven track record.
Superior Purity & Enrichment
Consistent ultra-high isotopic enrichment (98 atom%+ grades) and chemical purity (99.99%+) that protect your cyclotron target, synthesis process, and final radiopharmaceutical from contamination-related failures.
Reliable & Stable Supply
As a professional manufacturer, we offer better supply security and scalability compared to traders and middlemen who depend on others for stock.
Lower Total Cost of Ownership
Direct supply = competitive price + fewer batch rejections + less cyclotron downtime + higher radiolabeling yield. You save money where it matters most — not just on the raw material price.
Full Traceability & Compliance
Complete production traceability and international certifications that meet the demanding requirements of the Nuclear Medicine, Radiopharmaceutical, and Life Science Research industries.
Technical Expertise
Real manufacturer knowledge to support your specific application — not just selling the liquid, but helping you use it optimally for PET synthesis and research.

Frequently Asked Questions (FAQs)
Q1: Are you a manufacturer or a trading company?
A: We are a direct manufacturer with our own production facilities. This ensures the best quality control, stable isotopic enrichment, competitive pricing, and a reliable supply chain directly to you without middleman markups.
Q2: Is Oxygen-18 Water hazardous?
A: No. Oxygen-18 Water (H₂¹⁸O) is a stable, non-radioactive, and non-flammable liquid isotope of regular water. It is safe to handle under normal laboratory conditions. However, because it is an extremely high-value material, proper handling and clean storage are recommended to avoid contamination. It is not classified as dangerous goods for shipping.
Q3: Are you qualified by multinational companies?
A: Yes. We are an approved and qualified supplier to several global multinational corporations and radiopharmaceutical companies. Our Oxygen-18 Water has successfully passed their rigorous audits, isotopic enrichment tests, and long-term performance evaluations.
Q4: Do you offer international shipping?
A: Yes. We ship globally with a reliable logistics network. We handle all necessary documentation to ensure smooth delivery. The product is packaged in shock-proof materials to guarantee safe and secure delivery to your destination.
Q5: What industries do you supply Oxygen-18 Water to?
A: We supply high-enrichment Oxygen-18 Water primarily to the Nuclear Medicine / PET Imaging Industry (as the precursor for ¹⁸F-FDG production), Radiopharmaceutical Manufacturing, and Life Science Research (such as metabolic tracers).
Q6: What is your Minimum Order Quantity (MOQ) and do you provide samples?
A: Our MOQ is flexible. We can accommodate small quantities for R&D purposes (e.g., 1g or 5g vials) as well as bulk orders for commercial production. We can also provide samples for your strict quality and enrichment testing upon request.
Q7: What packaging options do you offer?
A: We supply Oxygen-18 Water in sealed, sterile glass vials or ampoules in various sizes ( 1g, 5g, 10g, 20g, up to 100g e.g ) to suit small R&D needs to large commercial production volumes.
Q8: How fast can you deliver?
A: Lead time depends on quantity and destination. We maintain strategic stock of standard specifications and have global logistics experience serving multinational customers worldwide.
