JOANLAB dry block bath · DB-100 series
Dry block bath with ±0.5 °C stability and nine interchangeable blocks; the DB-100C cools below ambient and the DB100-2P takes two at once.
- Nine interchangeable blocks, from 96 × 0.2 mL to 6 × 50 mL, plus a cuvette module
- Ambient to 100 °C on the DB-100; down to 15 °C below ambient on the DB-100C
- The DB100-2P takes two blocks at once and allows them to be combined freely
- Nine programmable temperature points and a timer from 5 s to 23 h 59 min
Summary datasheet
| Available blocks | Eleven blocks in the catalog, nine of them interchangeable, from 96 × 0.2 mL to 6 × 50 mL. The block is NOT included: the price list indicates that the machine ships without any block and that blocks must be ordered together with it |
| Temperature range | Ambient to 100 °C (DB-100 and DB100-2P); from 15 °C below ambient up to 100 °C (DB-100C) |
| Block bays | One on the DB-100 and the DB-100C; two of 110 × 75 × 32 mm on the DB100-2P |
| Stability and uniformity | ±0.5 °C |
| Readout resolution | 0.1 °C |
| Heating rate | Up to 5.5 °C/min |
| Cooling rate | 5 °C/min from 100 °C down to ambient temperature and 1 °C/min below it; only on the DB-100C |
| Programming | Nine temperature points, from P1 to P9 |
| Timer | 5 s to 23 h 59 min |
| Block catalog | 96 × 0.2 mL; 48 × 0.5 mL; 35 × 1.5 mL; 35 × 2.0 mL; 24 × 5.0 mL for blood tubes; 12 × 5/15 mL; 6 × 50 mL; 24 × 2.0 mL for cryovials; cuvette module; flat-bottom plate and aluminum beads. The manufacturer marks the last two as "non-replaceable modules" |
| Power | 96 W (DB-100 and DB-100C); to be confirmed on the DB100-2P |
| Power supply | AC 100-240 V (DB-100 and DB-100C); AC 110/220 V (DB100-2P) |
| Dimensions | 280 × 180 × 85 mm on the DB100-2P according to the 2025 edition; the 2026 edition removed that row and states no dimensions for any model |
| Shipping package | 28 × 20 × 15 cm and 2.5 kg (DB-100 and DB-100C) |
| Availability | Import to order / to be confirmed |
Base, C, or two modules at once
The DB-100 is the plain block; the DB-100C adds cooling below ambient (from 15 °C under room temperature, settable from −5 °C) and multi-point operation; the DB100-2P mounts two modules at once, freely combined, at 200 W. All three store nine programs and share the 5 s to 23 h 59 min timer.
It states stability and homogeneity separately
±0.5 °C stability and ±0.5 °C homogeneity, with a 0.1 °C readout and 5.5 °C/min heating. They are two different figures and the catalog publishes both: how much the block drifts over time and how much it varies from one well to another.
Eleven blocks, nine of them interchangeable
The module chart runs from the 0.2 mL tube (96 positions) to the 50 mL conical, and includes 1.5 and 2.0 mL, 5 and 15 mL tubes, a flat plate for microplates, a cuvette module, aluminum beads and 2 mL cryovials; the flat plate and the beads come in fixed configuration. Custom modules are available (OEM).
