Cardboard or fibre drums can also raise GMP concerns in higher-grade areas. One solution is to install the isolator on the floor above and connect it by a closed pipe or chute &mdash; but long chutes can be difficult to clean or clear if they block. A mobile isolator docked to the charge port through a closed connection is another option, though it is rarely used in practice because the closed-connection system is hard to design (usually needing a lift operation) and the dispensing scale must be re-calibrated after each move.<\/p>\n<h2>Choosing a containment approach<\/h2>\n<p>The right method balances potency, batch size, ergonomics and cleaning.
