ALEMADR-TSHL thermo shaker with heating lid — dual block, 200–2000 rpm, RT+5 °C to 100 °C
The ALEMADR-TSHL is a dry-block thermo shaker with heating lid for microtubes, PCR plates and related tube formats. Two blocks, orbital shaking to 2000 rpm and PID temperature control are combined with a lid that is heated independently of the block, which is what keeps condensate off the caps and the sample volume where it started. Product code PRO6399.
Two blocks, 2000 rpm and a heated lid
A dry-block instrument holds the sample at a set temperature; a shaker keeps it moving. The ALEMADR-TSHL thermo shaker with heating lid does both on two blocks at once, from 200 to 2000 rpm on a 2 mm orbit, between room temperature +5 °C and 100 °C. The heated lid is the third element and the one that decides whether a long incubation ends with the volume you started with.
Key characteristics
- Dual block — two blocks run together, so one instrument covers two tube formats or twice the batch.
- Shaking 200–2000 rpm on a 2 mm orbit, set digitally on the LCD.
- Temperature RT+5 °C to 100 °C, PID controlled, accuracy ≤ ±0.2 °C at 37 °C.
- Independently heated lid, Auto or 0 to +15 °C above block temperature.
- Timer 1 min to 99 h 59 min or continuous running.
- Multi-cycle and multi-point programs — up to 99 cycles, up to 5 temperature points.
- Heating time ≤ 15 min from 25 °C to 100 °C.
- Brushless DC motor, quiet and maintenance-free.
Suitable for
- Enzyme and nucleic-acid incubations in 0.2, 0.5, 1.5 and 2.0 ml tubes.
- PCR plate handling where the plate must be mixed and held at temperature.
- Protein work and catalysis that needs shaking at a controlled temperature.
- Long incubations where evaporation would otherwise change the concentration.
- Laboratories that want one thermo shaker with heating lid to cover two tube formats at one bench position.
Why a thermo shaker with heating lid, and not a plain dry block
In a heated block the coldest surface in the tube is the cap. Vapour condenses there, the liquid volume drops and the concentration of everything left behind rises — which is exactly what a long incubation must not do. A thermo shaker with heating lid heats the cap zone a few degrees above the block, so there is no cold surface for vapour to condense on. On the ALEMADR-TSHL that lid is controlled independently, automatically or set manually from 0 to +15 °C above the block.
The second effect is uniformity. Without lid heating the temperature at the top of the tube is lower than at the bottom; with it the gradient is much smaller, which matters when the protocol specifies a temperature and not a range. A thermo shaker with heating lid also reduces the aerosol that forms when a warm tube is opened, and with it the cross-contamination risk in a plate of parallel samples.
Model, product code and identification
The ALEMADR-TSHL is supplied as a base unit; blocks are chosen separately according to the tube format. Quote and order with the COLO product code.

Operating functions
Temperature and lid
Block temperature is set from 0 to 100 °C and controlled from RT+5 °C upwards, with 0.1 °C resolution on the display. The lid runs in Auto, where it tracks the block, or is set manually from 0 to +15 °C above it. Automatic preheating brings the block to temperature before the run starts, and the instrument can hold the temperature after the timer ends.
Shaking
Speed is adjustable from 200 to 2000 rpm on a 2 mm orbit. The low end suits gentle mixing of protein solutions, the high end resuspends pellets in small volumes. Shaking and heating are set independently, so a protocol can heat without shaking or shake at room temperature.
Programs and timing
The timer covers 1 minute to 99 hours 59 minutes, or continuous running. Multi-point programs hold up to five temperature steps in sequence and multi-cycle repeats a program up to 99 times, which covers the temperature-step protocols that would otherwise need someone to stand at the bench.
Build, motor and safe operation
Inside the ALEMADR-TSHL thermo shaker with heating lid the drive is a brushless DC motor: no brushes to wear, no service interval, no carbon dust near open samples, and quiet enough for the instrument to stay on a working bench rather than being moved to a back room.
Over-heating protection is built in. Power is 450 W from AC 220 V or AC 110 V at 50/60 Hz — the voltage is chosen at order, so confirm it before the order is placed. The instrument measures 296 × 212 × 164 mm and weighs 6.9 kg without blocks, which is a normal bench footprint next to a centrifuge or a PCR cycler.

Applications and operational value
In molecular biology a thermo shaker with heating lid sits between sample preparation and the cycler: restriction digests, ligations, reverse transcription and bead-based clean-ups all need a fixed temperature with movement, in tube formats that change from one protocol to the next. Two blocks mean the 1.5 ml digests and the 0.2 ml plate do not wait for each other.
In protein and enzyme work the value of a thermo shaker with heating lid is in the lid itself. An overnight digestion at 37 °C in a 0.5 ml tube loses a measurable part of its volume without lid heating, and the measurement at the end is of a sample that concentrated itself. With the lid heated the volume at the end is the volume at the start.
In routine laboratories the multi-point program of this thermo shaker with heating lid does the work someone would otherwise do by hand: a heat step, a hold, a second temperature, repeated up to 99 times. The practical limit is not the instrument but how many tubes fit the chosen block, which is why the block list matters as much as the specification table.
Selection guide
- Tube format first. The block decides what the instrument can take: PCR plate, 0.5 ml, 1.5 ml, 2.0 ml or a mixed layout. Count the tubes per run before choosing.
- One format or two. A dual-block thermo shaker with heating lid is worth it when two formats run in parallel; for a single format a single-block model is enough.
- Temperature range. RT+5 °C to 100 °C covers incubation and denaturation but not cooling — if the protocol needs sub-ambient temperature, choose a cooling model.
- Lid. Long incubations and small volumes justify the heating lid; a five-minute mix at room temperature does not.
- Voltage. AC 220 V or AC 110 V is fixed at order — confirm which one the laboratory uses.
