Benchmark Scientific HC-24 C3450-H Hematocrit Capillary Centrifuge, 24-Place, 12,000 rpm / 14,328 × g, Reading Disc Lid Included

Product Description

The Benchmark Scientific HC-24 C3450-H is a compact hematocrit capillary centrifuge — purpose-built for rapid, accurate hematocrit determination in clinical, veterinary, and research laboratory environments. With a 24-place rotor for 75mm capillary tubes, programmable speed of up to 12,000 rpm (14,328 × g), and a reading disc conveniently built into the lid for immediate analysis, the HC-24 eliminates the need for separate reading accessories and streamlines the hematocrit workflow from centrifugation to result in a single instrument. The large digital display offers precise control of speed (rpm or rcf) and run time, with a timer range from 20 seconds to 99 minutes. Rapid acceleration to maximum speed in under 20 seconds. 2-year warranty. 110 to 230V, 50-60Hz — worldwide compatible.

Reading Disc Built Into the Lid — Immediate Analysis Without Separate Accessories The defining convenience feature of the HC-24 is its reading disc built directly into the centrifuge lid — allowing immediate hematocrit reading immediately after the centrifuge stops, without removing tubes from the rotor or reaching for a separate reading chart, card, or wheel. The reading disc is conveniently built into the lid allowing for immediate analysis and eliminating the need for separate accessories. This integrated design eliminates one of the most common workflow inefficiencies in hematocrit testing — the need to carefully transport capillary tubes from the centrifuge to a separate reading station without disturbing the packed cell column. With the HC-24, centrifugation and reading happen at the same instrument in a single uninterrupted workflow.

24-Place Rotor — Maximum Throughput for Hematocrit Testing The HC-24 accommodates 24 standard 75mm hematocrit capillary tubes simultaneously — allowing up to 24 hematocrit determinations per run. For clinical laboratories, veterinary practices, blood banks, and research facilities processing multiple samples simultaneously, the 24-place capacity maximizes throughput and minimizes the number of centrifuge runs required per sample batch. The rotor accepts standard 75mm hematocrit capillary tubes — both plain and heparinized — compatible with all major capillary tube suppliers.

12,000 rpm / 14,328 × g — Rapid, Complete Packed Cell Volume Determination The HC-24 achieves a maximum speed of 12,000 rpm and 14,328 × g — the high centrifugal force required for complete and accurate packed cell volume (PCV) determination in hematocrit capillary tubes. At 14,328 × g, the HC-24 achieves complete cell packing in standard hematocrit run times, producing accurate and reproducible PCV results consistent with clinical laboratory standards for hematocrit determination.

Rapid Acceleration — Max Speed in Under 20 Seconds The HC-24 features rapid acceleration to maximum speed in under 20 seconds — reaching the full 12,000 rpm operating speed faster than most competing hematocrit centrifuges. At 20 seconds acceleration time (Accel: 20s / Decel: 30s), the HC-24 minimizes the total time from run start to result — particularly important in high-throughput clinical environments where multiple sample batches are processed throughout the day and cycle time directly affects laboratory throughput.

Quick-Spin Function — Instant Centrifugation for Urgent Samples The Quick-Spin function allows the operator to initiate immediate centrifugation without programming speed or time — ideal for urgent STAT samples requiring immediate processing. The Quick-Spin function operates the centrifuge at maximum speed for an operator-defined period with a single button press, eliminating the programming steps required for standard runs.

Programmable Timer — 20 Seconds to 99 Minutes Timer up to 99 mins, continuous. The wide timer range of the HC-24 — from 20 seconds to 99 minutes in programmable increments — accommodates the full range of hematocrit centrifugation protocols. Standard hematocrit runs are typically 3–5 minutes at maximum speed, but the extended timer range supports specialized protocols, additional spin times for difficult samples, and continuous operation for high-volume processing environments.

Large Digital Display — Precise Speed and Time Control The large digital display offers precise control of speed (rpm or rcf) and run time. The HC-24 displays both rpm and RCF (relative centrifugal force) — allowing operators to work in the units specified by their protocol. Speed can be programmed in increments across the full 1,000 to 12,000 rpm range, providing flexibility for applications requiring speeds below the maximum.

Compact Footprint — Benchtop Efficient Dimensions: 14 × 11 × 9.8 in. / 36 × 28 × 25 cm. Weight: 35 lbs / 16 kg. The HC-24's compact footprint occupies minimal benchtop space — an important consideration in clinical and veterinary laboratory environments where counter space is shared across multiple instruments. The 35 lb weight provides sufficient stability during operation without requiring permanent installation.

110 to 230V, 50-60Hz — Worldwide Compatible Electrical: 110 to 230V, 50-60Hz, 880W. The HC-24's wide voltage input range makes it compatible with both North American (110V, 60Hz) and international (230V, 50Hz) power standards — allowing the same instrument to be used worldwide without voltage conversion requirements.

2-Year Warranty — Benchmark Scientific Quality Assurance The HC-24 C3450-H is backed by Benchmark Scientific's 2-year warranty — one of the most comprehensive warranty programs in the compact laboratory centrifuge segment. Benchmark Scientific is a US-based manufacturer of laboratory equipment with a strong service and support network.
