Au cours de cette exposition, Bacclean, avec sa force technique professionnelle, ses services de produits de haute qualité et ses solutions innovantes, a pleinement démontré sa compétitivité dans le domaine de l'épuration hospitalière, attirant de nombreux collègues de l'industrie pour échanger des technologies et des solutions dans le domaine de l'épuration médicale.
La 16ème édition de l'ASIA PHARMA EXPO s'est achevée avec succès à l'Asia Pharma Expo au Bangladesh le 13 février 2025. Guangzhou Bacclean a été très heureux d'apparaître avec ses distributeurs ce jour-là.
VHP pass-boxes are widely deployed in biosafety laboratories, sterile pharmaceutical workshops, semiconductor cleanrooms, medical device manufacturing and other sectors. Nevertheless, requirements for equipment classification, parameter configuration, material craftsmanship and safety standards vary drastically across different application scenarios. Inadequate equipment matching constitutes the primary cause of prevalent industry challenges including substandard sterilization, sample contamination, excessive maintenance costs and audit non-compliance.
In high-grade clean environments such as biosafety laboratories, sterile pharmaceutical workshops, and medical device cleanrooms, material transfer across zones represents a critical risk point for cross-contamination. Traditional UV transfer windows and air shower transfer windows suffer from inherent limitations—including sterilization blind spots, weak spore-killing capability, and residual contamination—which no longer meet the stringent requirements of updated GMP standards and biosafety regulations.
La salle blanche de classe 100 000 présente de nombreuses caractéristiques essentielles et revêt une grande importance. Ses normes de propreté strictes, ses éléments centraux parfaits et ses mesures précises de contrôle environnemental lui permettent de répondre aux besoins de production de multiples industries telles que les produits pharmaceutiques, électroniques et alimentaires, de garantir efficacement la qualité des produits, d'améliorer l'efficacité de la production et de réduire les risques de production.
As key purification equipment for material transfer between zones of different cleanliness grades, laminar‑flow pass‑boxes mitigate cross‑contamination risk in high‑grade clean environments. Different from conventional mechanical pass‑boxes, it realizes dynamic purification during transfer via vertical unidirectional laminar closed‑loop airflow. In accordance with GMP, EU GMP Annex 1 and PIC/S specifications, this paper introduces its top‑supply and bottom‑return laminar purification mechanism, sorts out critical technical indicators including chamber cleanliness, airflow velocity, filtration efficiency and housing material, and interprets the triple anti‑contamination system of electronic interlock, dynamic self‑cleaning and intelligent monitoring. By comparing with ordinary pass‑boxes, its superior dynamic anti‑pollution performance is highlighted. This work provides technical references for equipment selection, installation, commissioning and compliance‑oriented operation & maintenance.
In the advanced clean engineering system, laminar transfer windows and air supply ceilings do not operate independently but form a dual-coordinated prevention and control system that combines overall space purification and material transfer purification. The air supply ceiling is responsible for the air flow replacement and overall cleanliness maintenance in the clean room, while the laminar transfer window is responsible for blocking contamination during cross-regional material transfer. Working together, they can eliminate the two core sources of pollution in the space and materials, ensuring the dynamic cleanliness of the clean workshop to reach the standard. Based on the overall purification system perspective, this article analyzes the logical operation of the two devices, the key points of technical adaptation, and the engineering application value.
In pharmaceutical, biopharmaceutical, fine chemical and food testing industries, weighing booths serve as critical local clean units for material sampling, batching weighing and micro-dosing operations. They are also key equipment subject to intensive inspection during GMP certification. Its core function is to achieve three major objectives including dust containment, prevention of cross-contamination between materials and operator safety protection through precise airflow organization and enclosed structural design, while complying with mandatory requirements of the latest GMP concerning clean environment, pressure differentials and airborne particle control.
