ISOTEC has been supplying the laser and life science gas markets worldwide with gas mixtures for over fifteen years. We are committed to providing the highest quality of mixtures to our customers. ISOTEC supplies custom gas mixtures featuring labeled noble gases, 3He, and gases labeled with 13C, D, 17O, 18O, and 15N. Most mixtures are blended gravimetrically, ensuring the best possible reportable accuracy per component. All gas volumes are quoted at Standard Temperature and Pressure (STP). Analytical data confirming mix component ratios, isotopic and chemical purities accompany all orders.
We welcome Blanket Contract arrangements, when we can prepare a single batch of gas mix and reserve it for periodic, partial shipments over the term of the Contract. Please contact our Sales Office for a list of our Labeled Gases, or to discuss your Gas Mix requirements. Let us know the gas components, isotope enrichments, mix specifications and quantity required and we will quote price and delivery time.
