5911
5911
- The centrifuge model 5911 allows for tool-free rotor changes, except for the RA-410M3 rotor, and complies with the International Safety Standard IEC61010-2-020.
- Supports visual sample balance measurement for rotors operating at 5,000 rpm or less.
- Includes a memory function with five settings for spin-down operations.
- Operates based on centrifugal force (xg) with stepped and integral centrifuging settings.
- An optional foot switch is available for hands-free lid opening.
- Equipped with detectors for safe operations, stopping immediately if trouble is detected.
- Complies with GMP requirements and includes a tachometer port for rotor speed checks.
- Maintains sample temperature at 4˚C at maximum speed with an ambient temperature of 25˚C.
- Designed to reduce plastic use and support ecological recycling.
- Super-slow acceleration or deceleration is available for sensitive samples to avoid resuspension.
- Variable acceleration and deceleration functions allow customization to fit sample needs.
- New swinging bucket rotors ST-2504MS and ST-5004M, and new buckets for ST-722M are available.
- The ST-2504MS rotor has a maximum capacity of 4 x 250mL, a maximum speed of 4,800 rpm, and a maximum RCF of 4,300 xg.
- The ST-5004M rotor supports a maximum capacity of 4 x 500mL, a maximum speed of 4,000 rpm, and a maximum RCF of 3,080 xg.
- Various tube racks and sealing caps are available for biohazard-proof operations.
- The control system is micro-processor controlled with a brushless motor.
- Digital displays provide settings and indications for speed, RCF, time, g·sec, temperature, acceleration, and deceleration.
- The timer offers settings from 1 second to 990 minutes with various increments.
- The centrifuge uses R134a refrigerant, which is CFC-free.
- Power requirements vary based on voltage, supporting single-phase 50/60 Hz at different voltages and currents.
- Includes alarms for lid open, imbalance, over speed, high temperature, and electrical abnormalities.
- Designed to comply with international safety and GMP standards.
- Power consumption: 110/115V at 900W (3.2MJ/h), 220/230V at 850W (3.1MJ/h).
- Dimensions: 50(W) x 65(D) x 85(H) cm, Weight: 110kg.
- Certificates: IEC 61010-2-020 (except with RA-410M3 rotor), CE Marking for AC220V and 230V versions.
- Spare parts availability: Typically available for 10 years post-production discontinuation, except when parts cannot be procured.
- Read the instruction manual thoroughly before operation.
- Equipment is intended for use by individuals with technical knowledge; supervision is required for those without.
- Discontinue use if abnormalities are observed; turn off power, disconnect, and contact a distributor or Kubota Corporation.
- Keep the instruction manual accessible for reference.
- Do not handle equipment with bare hands if the rotor's defined lifetime has expired.
- Kubota has ISO 9001 and ISO 13485 certifications.
- Products are not for distribution in the USA, Canada, or Mexico.
