Multi-Chamber Cytocentrifuge

What is the Multi-Chamber Cytocentrifuge?

A multi-chamber cytocentrifuge holds several sample chambers, often six to twelve, and prepares many slides in a single run. It is chosen by busy laboratories that batch body-fluid samples throughout the day.

Overview

The multi-chamber cytocentrifuge expands the rotor to hold six, eight or twelve sample chambers, so a whole batch of body-fluid samples is concentrated in one spin. This matches the workflow of hospital haematology and cytology laboratories, where CSF, urine and effusion samples arrive in batches and need rapid turnaround. Rotors are designed so chambers balance in pairs or groups, and some instruments include holders for different chamber types or spot sizes. Speed and time settings are applied to the whole batch, so samples requiring very different conditions should be grouped appropriately. Because more chambers are handled, good organisation of cards, funnels and slides speeds disassembly and prevents mix-ups. Look for chamber numbering, a rotor map and easy-release clips to keep sample identity clear.

How does it work?

A cytocentrifuge is a low-speed centrifuge fitted with sample chambers that hold a microscope slide against a card or gasket. The fluid sample is placed in the chamber and centrifuged, so cells move out of suspension and settle onto the slide within a defined circle of typically 6 to 13 mm. Absorbent card or filter paper beside the slide wicks away the supernatant, leaving cells concentrated in a monolayer with minimal protein background. Spin speed and time, usually 500 to 1500 rpm for 3 to 10 minutes, control cell density and flattening. Faster spins pack more cells but flatten them and increase background; slower spins preserve nuclear detail. Some instruments add a cytology funnel, a slide clip and a disassembly system that protects the operator from aerosols.

What are the key features?

• Rotor for six to twelve sample chambers
• Batch processing in a single spin
• Numbered positions and rotor map
• Balanced loading in pairs or groups
• Holders for different chamber and spot types
• Designed for rapid batch turnaround

What are the technical specifications?

A typical multi-chamber cytocentrifuge configuration offers number of chambers of 6–12, spin speed of 200–2000 rpm, timer range of 1–99 min, spot diameter of about 6–13 mm, sample volume of 0.1–1 mL per chamber and throughput of up to about 12 slides per run. 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-Chamber Cytocentrifuge is used in high-volume body fluid cytology, hospital haematology laboratories, urine and CSF batch processing and cytology screening laboratories. Across the wider Cytocentrifuges class, laboratories also deploy it for cerebrospinal fluid cytology, body fluid cell counts and urine cytology.

Which standards and certifications apply?

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

Place the cytocentrifuge on a level bench and balance the rotor or chamber loads exactly as specified, because imbalance causes vibration and poor cell distribution. Use the recommended absorbent cards or filters and replace them for every sample to prevent carryover. Disassemble and clean chambers after use, and disinfect according to the laboratory biosafety policy, since samples may be infectious. Verify the timer and speed at defined intervals with a tachometer or service check. Record spin conditions for each sample, keep maintenance records and train staff in safe handling of aerosols and sharps from broken slides.

How do I select the right Multi-Chamber Cytocentrifuge?

Choose a multi-chamber model when samples arrive in batches and turnaround time is measured in minutes. Confirm chamber count, rotor balance requirements, available spot sizes and slide format. Plan bench space and consumable storage, since a full batch needs many cards, funnels and slides prepared in advance.

How does it compare with other Cytocentrifuges variants?

Choose a cytocentrifuge by sample type, daily volume and the number of chambers needed. Single-chamber models are economical and suit low volumes or occasional body-fluid work. Double and multi-chamber instruments process several samples in one run and reduce turnaround, which matters in busy haematology laboratories. A programmable unit lets you store spin protocols for different fluids, so fragile cells are not over-packed. Micro-volume models are designed for small samples such as paediatric CSF. Compare chamber design, spot size, spin speed range, timer resolution, aerosol containment, ease of disassembly and cleaning, and whether cytology funnels and slides are standard items. Check how the instrument handles blood-contaminated fluids, since red cell carryover affects interpretation.
