Serving R&D and process scale-up
Pharma & TCM
From TCM extract powders and solid-dose granulation to lyophilized biologics, R&D teams need to prove a process on small batches first.
See solutions →Nutraceutical, Food & Beverage
Instant powders, probiotics, encapsulated ingredients and functional blends depend on repeatable small-batch drying and granulation.
See solutions →Chemicals & Advanced Materials
Fine chemicals, cosmetic ingredients, pigments and battery or other advanced materials are often trialled on pilot equipment before scale-up.
See solutions →Universities & Research Institutes
University labs, research institutes and teams at Hong Kong Science Park (HKSTP) need flexible, right-sized lab and pilot equipment for method development, sample preparation and pilot studies.
