Product Overview

The REMI R-303 Doctor Centrifuge is a compact and dependable laboratory centrifuge designed for routine centrifugation and sample-separation requirements in medical clinics, pathological laboratories, hospitals, diagnostic centres, medical practices and other laboratory environments.

Designed by REMI, the R-303 combines a compact benchtop design with an 8 × 15 mL angle-head rotor, allowing up to eight tubes to be processed simultaneously. With a maximum speed of 3800 RPM and maximum relative centrifugal force of 1450 × g, the centrifuge is suitable for a wide range of routine sample-processing applications.

The R-303 uses a resiliently mounted motor intended to provide smooth operation with reduced vibration. A built-in 5-step speed regulator provides simple manual speed adjustment, making the instrument straightforward to operate in routine laboratory environments.

Its compact construction makes it particularly useful where laboratory bench space is limited while still providing sufficient capacity for everyday centrifugation requirements.

Key Features

1. 8 × 15 mL Rotor Capacity

The R-303 is equipped with an 8-position angle rotor designed to accommodate up to eight 15 mL tubes simultaneously.

This allows multiple samples to be processed during a single centrifugation cycle, helping improve routine laboratory workflow.

2. High-Speed Centrifugation

The centrifuge provides a maximum speed of 3800 RPM.

This operating speed, combined with the rotor configuration, provides effective centrifugal force for routine separation procedures.

3. Maximum RCF of 1450 × g

The R-303 can generate a maximum relative centrifugal force (RCF) of 1450 × g.

RCF is the centrifugal force acting on a sample and is an important parameter when selecting centrifugation conditions for different laboratory procedures.

4. Angle-Head Rotor

The R-303 uses an angle-head rotor. Tubes are held at a fixed angle during rotation, making the configuration suitable for routine sample separation.

The angle-head arrangement also allows the centrifuge to maintain a compact footprint.

5. 5-Step Speed Regulation

A built-in 5-step speed regulator allows the operator to select the appropriate speed for the centrifugation requirement.

The simple control arrangement makes the instrument easy to use without requiring complicated programming.

6. Resiliently Mounted Motor

The R-303 is fitted with a resiliently mounted motor designed to help provide stable operation and minimize vibration during centrifugation.

Correct tube balancing and proper loading remain essential for safe and smooth operation.

7. Compact Benchtop Design

With dimensions of approximately 210 × 210 × 250 mm, the R-303 is designed to occupy relatively little laboratory bench space.

Its compact construction makes it suitable for clinics, small laboratories and diagnostic facilities where workspace is limited.

8. Single-Phase Electrical Supply

The unit is designed for a 220–240 V, 50 Hz, single-phase electrical supply, making it suitable for standard laboratory electrical installations in India.

Technical Specifications

The core specifications above are consistent with REMI's published R-303 information and current Indian laboratory-equipment listings.

Applications

The REMI R-303 can be used for routine centrifugation requirements in a variety of professional environments.

Medical Laboratories

Suitable for routine centrifugation of laboratory samples as part of standard sample-processing workflows.

Pathological Laboratories

The R-303 is designed for the small-capacity centrifugation requirements commonly encountered in pathology laboratories.

Hospitals

Its compact size and 8-tube capacity make it suitable for routine centrifugation requirements in hospital laboratory environments.

Clinics and Medical Practices

The compact benchtop format makes it practical for medical practices requiring an in-house centrifuge for routine sample processing.

Diagnostic Centres

The instrument can be incorporated into routine diagnostic laboratory workflows where controlled centrifugation is required.

Educational Laboratories

Its straightforward controls and compact configuration can also make it useful for teaching and demonstration of basic centrifugation principles, subject to the laboratory's protocols.

How the REMI R-303 Works

Centrifugation separates components of a sample by using centrifugal force.

When tubes containing samples are placed into the rotor and the centrifuge is operated, the rotor rotates at high speed. Components within the sample respond differently to the centrifugal force depending on factors such as their density and size.

During centrifugation, denser components tend to move toward the bottom of the tube while lighter components remain closer to the upper portion. This separation can make it easier to process or examine different fractions of a sample.

The R-303 provides a maximum speed of 3800 RPM and maximum RCF of 1450 × g, providing the centrifugal force required for many routine laboratory procedures.

Advantages of the REMI R-303

Compact Footprint

The small footprint makes the R-303 convenient for laboratories where bench space is limited.

Multiple Samples per Run

With capacity for eight 15 mL tubes, multiple samples can be processed simultaneously.

Simple Operation

The 5-step speed regulator provides straightforward manual control without complicated programming.

Reliable Routine Performance

The resiliently mounted motor is designed for stable operation during regular centrifugation work.

Practical for Medical Environments

The R-303 is specifically positioned by REMI for routine centrifugation requirements in medical practices, pathological laboratories and hospitals.

Easy Integration into Existing Workspaces

The compact dimensions and standard single-phase electrical supply allow the centrifuge to fit easily into many laboratory setups.

Rotor Capacity

The R-303's 8 × 15 mL angle-head configuration provides:

Total tube positions: 8
Maximum nominal tube capacity: 15 mL per tube
Rotor configuration: Angle head
Maximum speed: 3800 RPM

This configuration is suitable for laboratories that regularly process several relatively small-volume samples in a single batch.

Operating Considerations

For safe and effective centrifuge operation:

• Always place compatible tubes into the rotor correctly.
• Balance opposing tubes appropriately before starting the centrifuge.
• Do not exceed the recommended tube capacity.
• Inspect tubes for cracks, damage or leakage before use.
• Ensure that the rotor is properly installed before operation.
• Do not operate the centrifuge with an improperly secured lid.
• Use the appropriate centrifugation speed for the specific sample and laboratory procedure.
• Follow the manufacturer's operating and maintenance instructions.
• Clean the rotor and centrifuge chamber regularly.
• Stop operation immediately if excessive vibration or unusual noise occurs.

Important: Centrifugation parameters should be selected according to the laboratory's validated procedure and the requirements of the sample being processed.
