Multipurpose Refrigerated Centrifuge (4 x 100 mL)
Multipurpose Refrigerated Centrifuge (4 x 100 mL) - ToronCent™ HSR MP100
ToronCent HSR MP100 compact refrigerated centrifuge occupies 380 x 660 x 330 mm of bench space and draws 1 kW. Fifteen rotors mount on the drive, covering microtubes, PCR strips, hematocrit capillaries, 15 and 50 mL conical tubes, blood collection tubes, 100 mL bottles, and 96-well plates. Speed reaches 18,500 rpm and relative centrifugal force reaches 29,302 x g. Chamber temperature sets anywhere from -20°C to 40°C, with pre-cooling available before the first run.
Peak speed and peak force belong to different rotors. The 12 x 1.5/2.2 mL angle rotor turns fastest at 18,500 rpm and 23,797 x g, while the 24 x 1.5/2.0 mL rotor generates the 29,302 x g maximum at 17,500 rpm. Two rotors carry the 4 x 100 mL format: an angle rotor rated 10,000 rpm and 10,744 x g, and a swing rotor rated 5,000 rpm and 3,773 x g. Sample geometry and required force decide between them.
Temperature control runs on a variable frequency compressor under PID regulation, which modulates cooling output continuously rather than cycling. A built-in condensation tank collects the water that forms on cold chamber walls, keeping it away from the drive housing and slowing corrosion. Rotor identification reads the installed rotor and holds speed at its rating. Named program memories, short spin, and adjustable free-parking time complete the operating set.
Multipurpose Refrigerated Centrifuge (4 x 100 mL) - ToronCent™ HSR MP100 Applications
Small footprint and broad rotor coverage make this a fit for laboratories that need clinical, molecular, and plate formats without dedicating three instruments to them.
- Clinical Chemistry and Hematology: measures packed cell volume with the 24-place hematocrit rotor and prepares serum and plasma from blood collection tubes
- Molecular Biology and PCR Workflows: spins 8-strip 0.2 mL PCR tubes in a dedicated rotor and pellets nucleic acid precipitates at up to 29,302 x g
- Immunoassay Laboratories: processes ELISA plates, deep-well plates, and filter plate reagent kits in the microplate rotor
- Cell Culture and Cell Biology: pellets cells in 15 mL and 50 mL conical tubes, then harvests up to 4 x 100 mL per run
- Protein Chemistry and Enzyme Assays: collects precipitated protein while the chamber holds near 4°C to preserve activity
- Satellite and Point-of-Care Laboratories: a 380 mm width and 1 kW draw suit rooms where bench space and circuit capacity are both limited
- Veterinary and Physician Office Laboratories: hematocrit, serum separation, and sediment preparation run on one compact unit
- Academic Teaching and Research Laboratories: fifteen rotors let a single instrument serve varied coursework and project formats
- Pharmaceutical and Biotechnology Quality Control: clarifies in-process samples under controlled temperature
Standards
Supplier technical documentation for this model cites no international test standards, and torontech lists none the manufacturer has not published. Order documentation should include the declaration of conformity and factory calibration data, and laboratories working under an accredited quality system will qualify the unit through their own equipment verification protocol.
Multipurpose Refrigerated Centrifuge (4 x 100 mL) - ToronCent™ HSR MP100 Key Features
The specification favors format coverage and unattended reliability over raw capacity: fifteen rotors, continuous-modulation cooling, and a drain path for the condensate that sub-ambient operation generates.
- Fifteen Rotor Options: angle, swing, hematocrit, PCR strip, and microplate rotors cover 0.2 mL tubes through 100 mL bottles on a single drive
- Dedicated Hematocrit Rotor: a 24-place capillary rotor runs packed cell volume determinations at 13,000 rpm and 17,369 x g
- PCR Strip Rotor: six 8-tube strips of 0.2 mL tubes spin at 13,000 rpm and 16,020 x g without transferring samples to individual microtubes
- VF Compressor with PID Temperature Control: cooling output modulates continuously against the setpoint instead of cycling on and off
- Built-In Condensation Tank: collected meltwater drains away from the drive housing, which slows corrosion and extends service life
- Pre-Cooling Function: the chamber reaches temperature before samples arrive, removing the warm-up delay at the start of a shift
- 7-Inch Touchscreen: setpoints and live run conditions display together on an interface that shows all parameters without switching views
- Named Program Memories: methods store under operator-assigned names rather than numbers, which makes recall unambiguous on a shared instrument
- Eleven Acceleration and Twelve Deceleration Rates: ramp selection plus settable free-parking time protects soft pellets and layered separations through braking
- Automatic Rotor Identification: the drive recognizes the installed rotor and enforces its individual speed limit as over-speed protection
- Multi-Point Self-Diagnostics: monitored faults include door interlock malfunction, over-speed condition, motor overheating, operator error, and communication loss
- Short Spin Function: a momentary spin collects droplets from tube walls without programming a full cycle
- Low Acoustic Output: noise stays at or below 62 dB(A), the quietest rating in this instrument family
- Dual-Frequency Supply: the unit accepts 50 Hz or 60 Hz at 220 V
Theory and Method
Compact chambers restrict rotor radius, and radius enters the force equation linearly: RCF = 1.118 × 10⁻⁵ × r × N², with r in centimeters and N in rpm. Speed enters as a square, so a short-radius rotor turning quickly recovers the force that a long-radius rotor produces at lower speed. The 24-place microtube rotor uses that relationship to reach 29,302 x g inside a chamber small enough for a 380 mm bench footprint.
Packed cell volume measurement works differently from most separations. Blood drawn into a capillary tube spins until the red cells reach a stable packed column, and the ratio of that column to total sample length gives the hematocrit. The result depends on reaching complete packing rather than on collecting a pellet, so reference methods specify a force and duration sufficient to reduce trapped plasma to a negligible fraction. The dedicated 24-place capillary rotor holds 13,000 rpm and 17,369 x g for that purpose.
Running a chamber below ambient dew point condenses atmospheric moisture on every cold surface. Water pools at the chamber base, migrates toward the drive seal, and attacks the housing over months of operation. A dedicated condensation tank intercepts that water and holds it for disposal. Ramp control matters for the sample itself: eleven acceleration and twelve deceleration rates, plus a settable free-parking time, let the rotor coast to rest slowly enough to leave gradients and loose pellets undisturbed.
