DRIVESHAFT SEALS

Packed gland

Sealed by several layers of asbestos or cotton yarn

    Sometimes used two boxes with intervening space separated by steam Problems:

    Too tight  strain on shaft, heavy wear

    Too slack  contamination

Magnetic drives

Easy seal as seperate parts, shaft does not penetrate vessel

One driving magnet, one driven magnet

Liable to slip at high power consumption

Can get some cellular grinding (disruption)

Very common in non-viscous fermentation broths at lab scale
