Laboratory Baths

JP Selecta laboratory baths

JP Selecta laboratory baths provide high-fidelity thermostatic control for critical processes of incubation, enzymatic reactions, paraffin melting, sample defrosting and stability testing.

Our range includes more than 50 specialised models that adapt to any experimental protocol. It covers from the conventional laboratory water bath and advanced sand-bath systems for high temperatures, to the thermostatic laboratory bath with internal forced circulation (uniformity up to ±0.1 °C) and industrial refrigerated units that cover working ranges from -20 °C to +200 °C.

All our devices are built with AISI 304 or AISI 316 stainless steel chambers stamped without welds, and incorporate intelligent digital PID control, programmable timer and advanced protection systems against over-temperature or dry running under strict biological and industrial safety standards.

Types of laboratory baths

The choice of an efficient laboratory bath depends directly on the demands of the test protocol. The catalogue is structured into specific families according to the required thermal range, the need for constant flow agitation, active cooling or automated ultrasonic cleaning.

Thermostatic baths

Product line that integrates the digital water and oil Precisdig models, the forced-recirculation system Agibat-20 and the high-volume industrial Precisbig equipment.

Versatile capacities from 5 L to 220 L, temperature ranges from +5 °C to +99.9 °C or 200 °C depending on the conductive fluid.

Their main technical advantage lies in their thermal stability of up to ±0.1 °C. They are used preferentially as a water bath for enzymology, serology and pharmaceutical quality control.

Water baths (bain-marie)

Univeba and Precisterm series, along with the specialised Termofin (paraffin bath) model. They cover volumes from 1.3 to 45 litres, reaching maximum temperatures of 110 °C using water or up to 200 °C as an oil bath.

They are the standard solution for routine reagent defrosting, thermal support in rotary evaporators and the preparation of media.

Ultrasonic baths

Ultrasons series (HD, Digit and Ultrasons-P). With capacities from 1.4 to 30 litres, high-power washing frequency of 42 kHz and digital temperature regulation up to 80 °C.

Applications in laboratories for degassing of liquids, acceleration of chemical reactions, cell disruption and deep cleaning of sieves, micropipettes and dental or optical instruments.

Refrigerated baths

Unitronic Vaivén C series and VB-1423 calibration systems. With capacities from 20 to 27 litres, operating at temperatures from 0 °C to 100 °C. They incorporate a hermetic compressor unit free of CFCs.

Applications in biological cultures of critical thermostability (moulds and yeasts) and official calibrations of glass viscometers in accordance with international standards ISO 3105 and ASTM D 445.

Comparative table for each type of bath

JP Selecta technology in laboratory baths

The engineering applied in our thermostatic equipment guarantees maximum instrumental repeatability and protects the integrity of the user's samples.

High-precision PID temperature control

The digital PID controllers in the thermoregulated bath guarantee stable and precise thermal regulation (±0.05 °C), eliminating the oscillations typical of ON/OFF systems. The display shows real temperature and set-point, and advanced models include RS-232 connectivity for integration with LIMS systems.

AISI 316 and AISI 304 stainless steel chambers

The standard series incorporate AISI 304 steel chambers stamped in a single piece, without joints or welds, to avoid leaks and facilitate hygienisation. Components of ultrasonic baths exposed to more aggressive fluids or acid reagents are built with high-resistance AISI 316 stainless steel.

Advanced protection against dry running

To mitigate the risk of structural damage to the INCOLOY-alloy shielded heating elements caused by involuntary evaporation of the conductive fluid, all equipment is designed under strict DIN 12877 international standards. The electronic level-detection system immediately cuts heating and lights up specific warning indicators in case of liquid shortage or accidental over-temperature.

Why choose our bath catalogue

JP Selecta stands out by offering more than 50 models in its catalogue, allowing laboratories to unify their thermostatic systems (water, oil, sand and ultrasonic) under a single technical brand.

This drastically simplifies annual calibration plans, the acquisition of compatible accessories and optimises the centre's technical maintenance service.

In addition, our products include calibration and repair services under warranty.
