What are Toll Processing/Contract Distillation Services?
Toll Processing allows you to outsource heat-sensitive distillations to Pope Scientific. With over 30 years of expertise in wiped-film molecular distillation, we have successfully developed purifications for customers of all sizes. Our capabilities range from lab-scale distillation to processing up to 20 metric tons per month. We handle the distillation and return all streams to you. Additionally, we offer in-process testing with our analytical tools.
Industries ServedSpecializing in High Vacuum Molecular Distillation, Evaporation, and Fractionation
Pope’s chemical distillation and toll processing services excel in critical and high-purity applications, offering an extensive range of specialized thermal separation technologies:
- Wiped-Film Molecular (Short-Path) Distillation – Designed for the purification and separation of heat-sensitive, high-boiling compounds, this technology operates under deep vacuum conditions—down to 0.001 mm Hg—and temperatures exceeding 325°C to minimize thermal degradation and maximize product purity.
- Wiped-Film Evaporation (WFE) – An efficient evaporation process used to concentrate products, remove solvents, and separate volatile components. WFE technology provides short residence times and excellent heat transfer, making it ideal for temperature-sensitive materials.
- Hybrid Distillation (WFE & Fractional Distillation Combined) – By integrating wiped-film evaporation with fractional distillation, hybrid systems provide enhanced separation performance for complex mixtures, enabling precise purification and recovery across a wide range of process conditions.
Our facility accommodates volumes from laboratory trials to large-scale production runs. As an FDA-licensed food processing facility, we follow Food GMP compliant procedures and can provide Kosher certification when needed.
Toll Distillation Manufacturing Provides Cost-Effective Solutions
At Pope, chemical toll manufacturing is our specialty. We offer flexible configurations of various equipment to customize contract distillation for your specific needs. Our equipment includes lab-scale, pilot-scale, and production-scale evaporators, as well as hybrid fractional distillation units. We also perform other small-scale processes.
Beyond meeting immediate production demand, processing with us allows you to gather real-world scale-up data and prove process viability on our equipment before making a major capital investment for your own facility.
Toll Processing Services for Heat-Sensitive Materials
Pope’s Short Path/Wiped-Film toll processing equipment excels in the separation and purification of materials with high boiling points, melting points, viscosity, or reactivity. Our high vacuum and short residence time processes ensure the highest quality and yield for your finished product, minimizing thermal degradation.
