Pope Scientific's Benchtop Isolation System for CBD extraction features a 5-liter crystallizer-reactor and a 4-liter nutsche filter-dryer. Circulators with programmable ramping temperature are provided for both. The crystallizer’s baffles and mixer design allow proper control of particle sizing and distribution while controlling temperature ramp down rate. The nutsche filter can be pressurized for fast filtering and crystal washing and uses a vacuum, in addition to heat for efficient drying, aided by a raising/lowering cake agitator blade. All processing surfaces are 316L SS with pharmaceutical grade polish, units are ASME Sec VIII stamped and certified for safety, (with CRN and CE-PED certification also available).
This same specialized two-vessel technique is utilized in pharmaceutical and high purity specialty chemical processing. At completion of crystallization, slurry is transferred to the nutsche for filtering, washing and drying. The crystallizer is meanwhile cleaned, recharged for another cycle and run, thus both vessels are efficiently operating simultaneously. The system may be used with crude extract, but far better purity and yield results occur with distillate material of high 80’s to mid 90’s in cannabinoid percentage. CBD product to beyond 99.9%, with undetectable THC, can be produced.
The laboratory Benchtop Isolation System can produce up to 1 kg of crystal and is excellent for small special batches, plus learning and applying techniques for CBD crystal production optimization.
