Hematocrit Centrifuge — 12,000 RPM · 14,800 × g · 24 Capillary Tube Rotor Included
Packed Cell Volume · Erythrocyte Fraction · Bilirubin Assessment · Doping Tests · Micro Blood Separation
Hematocrit determination demands a centrifuge purpose-built for capillary tube geometry, precise g-force, and repeatable timing — not a general-purpose microcentrifuge pressed into service with adapters. The CFG400101 is purpose-engineered for the job: 12,000 RPM, 14,800 × g, 24 capillary positions, and a 5-inch HD touchscreen that replaces the knob-and-timer panels that have characterized hematocrit centrifuges for decades.
Why Hematocrit Requires a Purpose-Built Instrument
General-purpose centrifuges with capillary adapters are a compromise that labs accept when budget or bench space forces the issue. The adapter geometry is rarely optimized for 75 mm capillary tubes, rotor balance at 12,000 RPM becomes a concern without a dedicated design, and the absence of an integrated microhematocrit tube reader means every result requires a separate manual measurement step that introduces read error and slows throughput. Conventional keypad-and-knob controls also make precise protocol programming tedious in a clinical workflow where speed and reproducibility are clinical requirements, not preferences.
The CFG400101 resolves each of these friction points. The dedicated 24-position capillary rotor is balanced and rated to the full 12,000 RPM — there are no adapters, no compromise geometry. The included Microhematocrit Tube Reader is integrated into the workflow from the first run, eliminating the separate measurement step. Ten acceleration rates and eleven deceleration rates give clinical and research users the protocol flexibility to match any established hematocrit method. And the 5-inch HD touchscreen brings the instrument's parameter interface to the same standard as modern analytical instruments, replacing the tactile ambiguity of legacy analog controls.
12,000 RPM · 14,800 × g — Purpose-Built Hematocrit Speed
Maximum speed of 12,000 RPM generates 14,800 × g — the centrifugal force established by clinical hematology protocols for reliable packed cell volume (PCV) determination. Speed accuracy held to ±30 RPM ensures the g-force applied to every run matches the protocol specification, run after run, without drift.
5-Inch HD Touchscreen — Modern Interface, Clinical Precision
A 5-inch HD touch display replaces the knob-and-timer controls that have defined hematocrit centrifuges since the 1970s. Direct parameter entry for speed, time, acceleration, and deceleration — with multiple user-defined program storage — makes protocol recall instant and eliminates the setting errors introduced by analog dials under time pressure.
10 Acceleration + 11 Deceleration Rates — Protocol Flexibility
Twenty-one programmable ramp profiles give the CFG400101 the flexibility to match any established hematocrit, PCV, or micro-blood separation protocol precisely. Gentle deceleration profiles prevent layer disturbance in sensitive separations — a capability absent from fixed-ramp hematocrit centrifuges where braking speed is fixed by motor design.
Integrated Microhematocrit Tube Reader — Eliminates a Workflow Step
The included Microhematocrit Tube Reader means hematocrit values are read directly from the rotor without moving tubes to a separate measurement device. One instrument handles centrifugation and measurement — reducing handling, reducing read error, and cutting the per-sample workflow to two steps: spin and read.
From blood draw to hematocrit result in minutes — no adapters, no separate reader, no manual conversion. The CFG400101's 24-position dedicated capillary rotor, integrated tube reader, and programmable timer deliver the complete hematocrit workflow in a single compact instrument rated to international IVD safety standards.

The Hematocrit Workflow — Four Steps, One Instrument
Step 1
Load Capillary Tubes
Load up to 24 heparinized capillary tubes into the dedicated rotor — no adapters, no rebalancing
Step 2
Set Protocol
Enter speed, time and ramp rates via the 5-inch HD touchscreen — or recall a stored program instantly
Step 3
Centrifuge at 14,800 × g
Run at up to 12,000 RPM with ±30 RPM accuracy — matching any established PCV protocol specification
Step 4
Read Directly
Apply the included Microhematocrit Tube Reader to the spun capillary — read PCV value immediately, no separate device
Rotor Options
24-Position Capillary Tube Rotor
Standard configuration. Accommodates 24 standard heparinized capillary tubes (1 mm × 75 mm format). Rated to 12,000 RPM / 14,800 × g. Balanced rotor designed specifically for this instrument — no adapter compromise. Microhematocrit Tube Reader included.
12-Position Capillary Tube Rotor
Optional half-capacity rotor for lower-throughput workflows or when processing odd-numbered sample batches where 24-position loading would leave unbalanced positions. Same speed rating as the standard rotor.
Ideal Applications
Clinical Hematology Laboratory
Routine packed cell volume and erythrocyte fraction determination from EDTA or heparinized whole blood. The integrated reader and programmable timer support high-throughput clinical workflows with consistent, reproducible results.
Neonatal & Pediatric Diagnostics
Photometric bilirubin assessment from neonatal blood specimens and micro-volume pediatric samples. The 24-capillary capacity accommodates the small sample volumes characteristic of neonatal draw protocols without batch size compromise.
Veterinary Practice & Sports Medicine
Hematocrit determination for animal hematology in veterinary clinics, and erythrocyte volume fraction analysis for doping control testing in sports medicine — both applications where the instrument's accuracy and IVD compliance are non-negotiable.
