Surge Scientific · Model TC0401003 · Quad-Block Sample Heater
Dry Bath Incubator
4-Block Sample Heater · LED Digital + PT1000
150°C Max · ±0.2°C Stability · Four Block Positions · External PT1000 Included · 99h Timer
Four block positions. One footprint. One set of controls. The TC0401003 is the high-throughput dry bath for labs that genuinely run parallel protocols — four different sample geometries on one unit, all held to ±0.2°C uniformity, all driven from a single PT1000 closed-loop controller, all running up to 150°C with a 99-hour timer on every block. Replaces a bench full of single-block heaters with one programmable instrument.
Why Four Blocks Earn the Bench Space
The honest version of running four single-block dry baths: four power cords, four calibration cycles, four separate interfaces, four sets of drift to monitor, and a bench that doesn't have four dry baths of space available. The second dry bath ends up on a cart. The third ends up on the floor. The fourth gets shared with the lab next door.
The TC0401003 puts four block positions on a single unit — four different sample types, four different temperatures if you want them, one auto-calibrated PT1000 controller, one 4-setpoint memory system, and one unit to maintain. The blocks themselves are interchangeable across 30+ standard geometries, so one instrument supports PCR tubes, 15 mL conicals, 50 mL conicals, cuvettes, and vials — simultaneously.
4 Block Positions
Four heating positions on one instrument. Different block geometries, different sample types, different setpoints if your protocol needs them — all with the same ±0.2°C precision.
PT1000 Closed-Loop
External PT1000 probe included. Drives heating from the actual sample temperature, not the block. Auto-calibration recalibrates the unit whenever the probe is connected.
±0.2°C Across All Blocks
Temperature stability and uniformity within ±0.2°C across every block. Display accuracy ±0.1°C. Every position behaves like a standalone precision heater.
Interchangeable Block Library
Compatible with 30+ anodized aluminum blocks — microtubes, conical tubes, cuvettes, PCR plates, vials. Mix four different geometries on one unit. Custom blocks on request.
"Four positions. One footprint. One controller." — The TC0401003 replaces four single-block dry baths with one programmable instrument — without compromising on the precision or the PT1000 closed-loop control that makes dry baths worth using in the first place.

Ideal Applications
High-Throughput Labs
Clinical diagnostic labs, contract research, blood banks, and production QC where parallel incubation across four sample types is the whole workflow.
Molecular Biology Core
Lab cores running PCR prep, ligation, digestion, denaturation, and conjugation in parallel — each at its own temperature, all on one instrument.
Teaching & Training
One instrument, four student stations, identical precision at every position — simplifies grading and eliminates station-to-station variability.
