The D2400-R is the BeadBlaster 24R Refrigerated — premium refrigerated variant of the BeadBlaster 24 family at $16,172 ($6,286 step-up over the non-refrigerated D2400 at $16,172.00). KEY DIFFERENTIATOR: integrated refrigeration system for temperature-controlled bead-mill homogenization at sub-ambient temperatures (typically 4 °C). Most-expensive bead-mill chassis in the catalog.
Author confidence note (MEDIUM): Universe label voltage spec ("120V, 50Hz or 240V, 60Hz") is unusual — typical universal-input chasses are 120V/60Hz or 240V/50Hz. Likely transcription quirk in universe label — confirm exact electrical compatibility with Benchmark Scientific.
Voltage options: This unit can be ordered with European voltage requirements (230V/50Hz). Contact us to order.

Why a Refrigerated Bead-Mill — Heat Generation During Cycles
Bead-mill homogenization generates substantial heat during high-energy cycles — bead impacts and friction within sample tubes raise sample temperature meaningfully (often 5-15 °C or more during long cycles). For heat-sensitive samples, this temperature rise causes RNA degradation (RNase activity accelerates with temperature, compromising yield and integrity), enzyme denaturation of heat-labile enzymes during pelleting / extraction, protein degradation or aggregation from heat stress, and cell / tissue thermal damage where heat-shock effects mask the biological signals of interest.
The D2400-R integrates refrigeration to maintain set-point temperature throughout homogenization cycles — eliminating thermal damage to sensitive samples.
Pick the BeadBlaster 24R (D2400-R) when:
- RNA extraction at production scale — RNA stability requires cold cycles
- Enzyme-prep and thermally-sensitive protein workflows at the bead-mill homogenization step
- Pharmaceutical / biotech / clinical research at high-stakes temperature-sensitive sample-prep
- Cold-room workflow consolidation — a refrigerated chassis eliminates cold-room dependence for bead-mill workflows
Stay with D2400 (non-refrigerated, $16,172.00) when room-temperature workflows match the routine — $6,286 saving when refrigeration isn't required.

Frequently Asked Questions
Q: Why choose a refrigerated bead-mill homogenizer? A: Bead-mill cycles generate substantial heat (often a 5–15 °C rise or more); integrated refrigeration holds a set-point temperature (typically down to 4 °C) throughout cycles, protecting heat-sensitive RNA, enzymes, and proteins.
Q: How does the D2400-R compare to the non-refrigerated D2400? A: The refrigerated 24R adds integrated set-point cooling for a +$6,286 premium ($16,172 vs $16,172.00); the non-refrigerated D2400 is the pick for room-temperature workflows.
Q: What is the sample capacity? A: 24-position, driven by a 600 W motor.
Q: What voltage does it use? A: The universe label lists an unusual "120 V / 50 Hz or 240 V / 60 Hz" — confirm exact electrical compatibility with Benchmark Scientific at order.
