F38-ME Forcing Test Refrigerated-Heating Circulating Bath

For the determination of the “best before” date of beer

The F38-ME large capacity recirculating bath designed for forcing testing of beer.  In conjunction with a photometer the  product life of beer can be determined.  The simulated aging process is achieved through a programmable temperature profile which is repeated until the first clouding develops.  All temperature profiles of the forcing test are pre-programmed.  The 45 L (11.9 gal) tank accommodates a rack insert holding up to 20 half liter bottles.  A removable Plexiglas cover is included.
