Frequently Asked Questions
What is a constant temperature water bath used for?
A constant temperature water bath is used to heat and maintain laboratory samples at a selected temperature. Common applications include reagent warming, sample incubation, pharmaceutical testing, culture media preparation, and analytical procedures.
Why is a stirrer used in the water bath?
The stirrer circulates water throughout the chamber and reduces hot or cold areas. This improves temperature uniformity and helps multiple samples receive more consistent thermal exposure.
What temperature range does the water bath support?
The typical operating range is from approximately 5°C above ambient temperature to near 100°C. The actual maximum temperature and control accuracy depend on the selected controller and chamber configuration.
What is the difference between contact and PID temperature control?
A contact thermometer with relay provides basic temperature regulation. A PID controller continuously adjusts heating output and generally offers improved stability, faster recovery, and closer control around the selected setpoint.
Is a digital timer available?
Yes. A programmable digital timer can be provided as an optional feature. It allows the operator to set a working duration and can stop the heating cycle after the programmed time.
How accurate is the constant temperature water bath?
The standard model offers accuracy of approximately ±1°C under normal operating conditions. PID-controlled versions can provide tighter temperature regulation, subject to chamber loading and laboratory conditions.
Can customized chamber sizes be manufactured?
Yes. Customized chamber dimensions, sample racks, controller types, exterior materials, and voltage requirements can be supplied for institutional and industrial projects.
Is the unit suitable for continuous operation?
The insulated construction, stainless steel chamber, and reliable heating system make it suitable for routine and extended laboratory use. Recommended water levels and operating limits should always be followed.
How should the water bath be maintained?
Drain and clean the chamber regularly, remove mineral deposits, and avoid operating the heater without sufficient water. The stirrer, controller, sensor, power cable, and safety system should also be inspected periodically.
What type of water should be used?
Clean distilled or demineralized water is recommended because it reduces mineral deposits, scaling, corrosion, and contamination inside the chamber. Water should be replaced regularly according to usage.
How is the water bath packed for shipment?
The unit is packed with protective cushioning and rigid outer packaging. Export orders may be supplied in reinforced wooden packing to protect the chamber, glass windows, controls, and accessories during transport.
Do you accept bulk and institutional orders?
Yes. Bulk supply is available for universities, pharmaceutical companies, hospitals, laboratories, distributors, research institutes, and government procurement projects.
