The Biobase BBS-H series comprises premium horizontal laminar flow cabinets designed to create a sterile Class 100 (ISO 5) work environment for non-hazardous samples. These cabinets utilize a horizontal airflow pattern where HEPA-filtered air is pushed from the back of the work zone toward the operator, ensuring that the sample is always bathed in a clean, unidirectional stream of air. The BBS-H1300 and H1800 models offer large work areas for complex procedures, while the H1100 and H1500 are optimized for more compact laboratory spaces. Each unit features a high-quality stainless steel work surface, a UV lamp for sterilization, and a microprocessor control system that ensures constant airflow velocity. These horizontal cabinets are ideal for applications such as plant tissue culture, media preparation, and the assembly of sensitive electronic or optical components where the sample must be protected from particulate contamination.
