ST1 Balance Enclosure

The ST1 Balance enclosures guarantee balance stability whilst providing proven protection from exposure to potent compounds. ST1 Balance weighing enclosure systems are specifically designed for the handling and weighing of potent compounds from milligram to kilogram quantities. In addition, the unique patented airflow and cleaning design provides a turbulence-free environment for sensitive analytical and microbalances. The ergonomic profile design makes the ST1 Potent Powder Weighing Enclosure comfortable and easy to use. These enclosures are designed with an increased internal depth therefore they can accommodate deeper balances whilst minimising bench space.
