Model 307 Sample Oxidizer Standard features The Model 307 Sample Oxidizer is an automatic preparation and oxidization system for both single and dual radiolabeled samples containing 3H and/or 14C for use in liquid scintillation counting. The 307 Sample Oxidizer ensures reliable combustion of biological, environmental and industrial samples. This system includes the following standard features and benefits: • Single “push button” operation initiates automatic cycle, positioning of vials and ignition basket, non-catalytic combustion, dispensing of scintillation cocktails and carbon dioxide trapping agent, and system cleaning. • Physical separation of 3H and 14C radionuclides from dual labeled sample material for ease of sample analysis. Model 307 Sample Oxidizer • Minimizes optical and chemical quenching. Reduces chemiluminescence in most sample preparations, increases statistical accuracy of liquid scintillation counting results. Eliminates self‑absorption. • Observation of combustion allows for visual inspection during sample burn. • Complete combustion of liquid, wet or dry samples eliminates the need for chemical solubilization. • Ensures maximum radionuclide recovery for 14C with sample size equivalent up to 40 millimoles of carbon dioxide and up to 85 millimoles of water for samples containing 3H (u

Model 307 Sample Oxidizer • Radionuclide recovery for both 3H and 14C of >97% constituent water vapor and carbon dioxide maximizes radionuclide separation for single label using a patented process to achieve physical separation of analysis using liquid scintillation counting techniques and an efficiency quench correlation curve for each radionuclide. • Radionuclide memory of less than 0.08% for most 3H and C labeled sample materials. • Non-catalytic combustion eliminates catalyst usage, cost and replacement. • Accommodates 20 mL glass or low cost polyethylene vials. • Capacity to process up...

Model 307 Sample Oxidizer 6. The four tanks are arranged left to right as follows (when viewed facing the front of the instrument) and are labeled on the front: a. Distilled water only. Performance specifications H Recovery: >97% b. Monophase® S (liquid scintillator for 3H). The performance is based on the use of: Monophase-S as c. Carbo-Sorb E (carbon dioxide absorber). the 3H liquid scintillator, Carbo-Sorb E as the CO2 absorber, d. Permafluor® E+ (liquid scintillator for C). (or similar) as sample material. Use of other reagents may Permafluor E+ as the 14C liquid scintillator, and...
