Benchtop Centrifuge

Sigma 3-18 centrifuge John Morris Scientific

The Sigma 3-18 and 3-18K high-speed benchtop centrifuges have maximum speeds of 16,000 and 18,000 rpm.

The air cooled 3-18 has a maximum capacity of 4 × 250 mL and is suitable for use in medical and research laboratories.

The refrigerated 3-18K can be used for tasks which require centrifugal forces up to 30,000g. The 3-18K enables rotor and chamber pre-cooling to 30oC and allows temperature control up to +40°C. Even at the highest speeds and during long runs, +4°C can be maintained.

Both models have 10 linear and 10 quadratic preprogrammed acceleration and deceleration curves as well as 50 storage places for additional programming needs. Important programs or functions can be PIN code protected.

Rotors include to 40 × 15mL and 16 × 50 mL fixed angle rotors for cell culture tubes. A 48 × 1.5/2/2 mL fixed angle rotor with polysulfone lid spins the microtubes. The 24 × 1.5/2.2 mL swing out rotor with windshield achieves 14,000 rpm and 16,215 × g.
