SELECTION NOTE — RITACUBA16R CENTRIFUGE CONFIGURATION
RITACUBA16R high-speed refrigerated centrifuge for flexible laboratory tube formats
The RITACUBA16R high-speed refrigerated centrifuge is a strong choice when a laboratory needs one compact refrigerated centrifuge for multiple sample formats. The rotor range covers 12, 24, 36 and 48-place microtube configurations, as well as rotors for 5 ml, 10 ml, 15 ml and 50 ml tube formats.
When selecting the final configuration, the first step is the tube format: nominal tube volume, bottom geometry, cap type, sample volume and tube manufacturer limits. The second step is the target RCF and temperature requirement. Maximum centrifuge performance depends on the selected rotor, compatible adapters, correct balancing and the rated limits of the consumables used in the method.
For routine laboratory use, COLO can help match the rotor and adapter set to PCR tubes, microcentrifuge tubes, conical tubes, round-bottom tubes or 50 ml formats, with attention to cooling profile, speed, RCF, throughput and SOP requirements.

Soft start / stop control
10 acceleration and 10 deceleration levels help adapt the run profile to more sensitive sample types and reduce unwanted disturbance during braking.
Stored programs
99 user-defined programs support repeated centrifugation routines with consistent speed, RCF, time, temperature and acceleration / deceleration settings.

COLO.SCIENCE KNOWLEDGE AND SUPPORT
Rotor selection support for refrigerated centrifugation workflows
COLO.Science supports centrifuge selection by matching tube format, sample volume, required RCF, temperature profile, rotor capacity, balancing requirements and routine laboratory SOP.
Applications and operational value
Molecular biology
RITACUBA16R supports high-speed refrigerated processing of common tube formats used in nucleic acid, protein and small-volume laboratory workflows.
PCR laboratories
Stored methods, instant centrifugation and compact benchtop footprint support repeated daily routines in PCR and molecular testing laboratories.
Bacterial separation
Rotor-dependent tube support and refrigerated operation make the platform suitable for routine bacterial separation and sample preparation tasks.
Multi-format laboratory use
Eight compatible rotors allow one centrifuge platform to support microtubes, round-bottom tubes, conical tubes and larger 50 ml formats.
How to select the appropriate RITACUBA16R rotor configuration
Rotor selection should start with the tube, not only with maximum speed. Confirm the nominal tube volume, tube bottom geometry, cap design, maximum fill volume, rated tube speed / RCF and whether an adapter is required. After the tube format is confirmed, compare rotor capacity, maximum speed, maximum RCF and required throughput.
For temperature-sensitive samples, define the target temperature, pre-cooling requirement and acceptable run profile. For sensitive samples, 10 acceleration and 10 deceleration levels can help adapt the start / stop behavior. All rotor configurations must be loaded symmetrically and operated according to the laboratory SOP and the consumable manufacturer’s rated limits.
Compact refrigerated centrifuge platform with eight rotor options
The RITACUBA16R high-speed refrigerated centrifuge is practical for laboratories that need refrigerated high-speed centrifugation without moving to a large floor-standing platform. Its desktop structure, 5-inch touch screen, automatic rotor identification, NCP composite rotor platform and 99 stored programs support routine use in PCR, molecular biology, molecular chemistry and sample preparation environments.
The broad rotor range is the main configuration advantage. Laboratories can select microtube rotors for high-speed small-volume work, higher-throughput microtube rotors for repeated daily processing, and larger tube rotors for 5 ml, 10 ml, 15 ml or 50 ml formats. Final rotor choice should always be aligned with sample volume, required RCF, tube limits, cooling profile and balancing rules.
