Multi-Purpose Programmable Benchtop Centrifuge

What is the Multi-Purpose Programmable Benchtop Centrifuge?

A multi-purpose programmable benchtop centrifuge accepts interchangeable swing-bucket, fixed-angle and plate rotors with stored methods and selectable ramps. It fits research and QC laboratories running varied tube formats and protocols on one instrument up to 15,000 rpm.

Overview

This class of benchtop centrifuge is built around interchangeable rotors, letting one instrument serve as a microtube centrifuge, a 15 mL and 50 mL conical tube unit and a plate spinner. Top speeds range from 6,000 to 15,000 rpm, generating up to about 21,000 x g with fixed-angle rotors. A touchscreen or keypad interface stores 50 to 100 programs, with continuous and short-spin modes, 10 acceleration and braking levels and RCF or rpm entry. Rotor recognition automatically limits speed to the installed rotor's rating. A heavy steel chamber and drive assembly allows rotors to be swapped in under a minute with a tool-free locking mechanism. Optional cooling models keep samples at 4 C. The format suits research groups with shared instruments and mixed workloads.

How does it work?

A benchtop centrifuge accelerates a rotor with a brushless DC or induction motor inside a guarded steel or composite chamber. The centrifugal force on each particle equals mass times angular velocity squared times radius, so particles denser than the medium move outward and form a pellet while lighter components remain in the supernatant. Swing-bucket rotors place tubes horizontal during the spin, which produces a flat pellet interface and suits blood tubes and gradients. Fixed-angle rotors hold tubes at 25 to 45 degrees, shortening the sedimentation path and giving faster pelleting. A microprocessor regulates speed, time and acceleration or braking curves, with a lid lock, imbalance sensor and rotor recognition providing safety.

What are the key features?

• Interchangeable rotors cover microtubes, conical tubes, plates and blood tubes
• Stores 50 to 100 programs with RCF or rpm entry
• Automatic rotor recognition limits speed to the installed rotor rating
• Tool-free rotor locking allows exchange in under one minute
• Short-spin mode and 10 acceleration and braking levels protect fragile samples

What are the technical specifications?

A typical multi-purpose programmable benchtop centrifuge configuration offers maximum speed of 6,000–15,000 rpm, maximum RCF of up to approx. 21,000 x g, rotor types of Swing-bucket, fixed-angle, plate, microtube, maximum capacity of 4 x 100 mL or 6 x 50 mL, program memory of 50–100 methods and speed accuracy of ±10 rpm. Values are indicative of the product class; the exact figures for each configuration are confirmed on the quotation and the calibration documents supplied with the instrument.

Which applications is it used for?

The Multi-Purpose Programmable Benchtop Centrifuge is used in research laboratories with shared instruments, molecular biology sample preparation, plate and microtube spinning and QC sample clarification. Across the wider Benchtop Centrifuges class, laboratories also deploy it for blood serum and plasma separation, urine sediment concentration and cell washing and harvesting.

Which standards and certifications apply?

Relevant standards and methods include IEC 61010-1, IEC 61010-2-020, IEC 61326-1, CLSI GP44, ISO 15189 and GB 4793.1. Certification candidates for this model are CE, ISO 9001 manufacturing and RoHS; each is to be confirmed for the specific configuration before shipment, and certificates are supplied only where they have been issued.

Place the unit on a rigid, level bench with at least 30 cm of clearance around it, and balance tubes within the maker's tolerance, commonly 0.5 to 1 g. Verify rotor speed with a tachometer and timer accuracy during annual calibration. Clean buckets and chamber with neutral detergent, avoiding chlorides that corrode aluminum, and inspect rotors for pitting or cracks. Record rotor cycles and respect rated lifetime. Clinical users should follow CLSI guidance on specimen processing and IEC 61010-2-020 safety requirements. Keep the lid open after use to prevent condensation and odor.

How do I select the right Multi-Purpose Programmable Benchtop Centrifuge?

Choose this variant when one instrument must cover several tube formats, plates and protocols, or when protocol transfer across users matters. It is more flexible than the low-speed unit and lighter than large-capacity models. In the RFQ, list every required rotor, maximum RCF, program count, display type and cooling preference.

How does it compare with other Benchtop Centrifuges variants?

Define the tube types first, since blood collection tubes, 15 mL and 50 mL conical tubes, and 96-well plates each require specific buckets or adapters. Next set the required RCF: serum separation typically needs 1,000 to 3,000 x g, while cell washing needs far less. Choose a swing-bucket rotor for clean pellets and plates, and a fixed-angle rotor when speed matters most. Consider capacity, such as 4 x 100 mL or 6 x 50 mL, programmable ramp profiles that protect fragile cells, and noise below about 60 dB for shared spaces. Add aerosol-tight lids if infectious material is handled. If samples are temperature sensitive, consider a refrigerated model instead.
