The "Rigid Isolator" is a containment device designed to ensure the safety of operators when handling highly pharmacologically active pharmaceuticals and highly toxic chemicals. This device, capable of achieving a high level of containment, controls internal pressure to minimize the risk of leakage of highly pharmacologically active pharmaceuticals, thereby providing greater safety for operators. Additionally, it is designed to prevent external exposure by installing HEPA filters in the intake and exhaust lines. 【Features】 ■ Supports containment at OEL levels of 0.1 to 100 μg/m3 ■ Capable of containing various process equipment such as mixers, dryers, and grinders ■ Easy to disassemble and clean ■ Designed, manufactured, and provided with after-sales support domestically ■ Custom-made options available to suit operational and cleaning methods *For more details, please download the PDF or feel free to contact us.
