Single-Chamber Cytocentrifuge

What is the Single-Chamber Cytocentrifuge?

A single-chamber cytocentrifuge processes one sample at a time and is the most economical option. It suits low-volume laboratories, occasional body-fluid work and research groups that prepare a few slides per day.

Overview

The single-chamber cytocentrifuge holds one sample chamber and slide, so a run produces one or two cell spots. Spin speed is adjustable, usually from about 200 to 2000 rpm, with a timer that can be set in 1 minute steps or finer. The sample chamber, funnel, absorbent card and slide clip are the core components, and disassembly after each run is straightforward. Turnaround per sample is short, but throughput is inherently low, so the instrument is best where volumes are modest or where only selected fluids need concentration. Because a single chamber is simple, there is less to clean and fewer seals to maintain, which reduces both cost and contamination risk. Aerosol containment depends on the lid and rotor design, so check how the chamber is closed and opened after the spin.

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?

• One sample chamber and slide per run
• Adjustable spin speed about 200–2000 rpm
• Timer settable in fine steps
• Simple disassembly and cleaning
• Low cost with few seals to maintain
• Compact bench footprint

What are the technical specifications?

A typical single-chamber cytocentrifuge configuration offers number of chambers of 1, 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 and slide format of 25 × 75 mm standard. 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 Single-Chamber Cytocentrifuge is used in low-volume body fluid cytology, research cell preparations, small clinics and teaching 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 Single-Chamber Cytocentrifuge?

Choose a single-chamber unit when daily slides are few, budget is limited and space is tight. It is not suited to busy laboratories that need many preparations quickly. In the RFQ state spin speed range, timer resolution, spot size, sample volume and the chamber and card consumables.

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.
