Obtain better distribution of media and uniform gassing with these benchtop rollers, designed to continuously rotate cylindrical bottles at optimum speeds. Transistorized solid state circuitry allows exact speed control of the bottles and is designed to compensate against sudden or prolonged voltage changes. Roller shafts are mounted in self-lubricated nylon bearings, which eliminate many maintenance problems. Order bottles separately.

Small bottle benchtop roller culture systems are designed to roll two bottles from 108 to 121 mm in diameter, and up to 290 mm long. Two outside rollers can be moved inward to accommodate bottles as small as 75 mm in diameter. Roller speed is 0.1 to 3.8 RPM for 100mm bottles. Order up to two additional deck kits to increase your rolling capacity.
