Laboratory constant temperature water bath

• L20WB-S 20L laboratory water bath is a multi-functional thermostatic instrument, suitable for routine and specialized experiments such as incubation, tissue culture, enzymatic reactions and fermentation analysis in research & testing labs.
• It adopts microprocessor temperature control and PT1000 high-precision temperature sensor, with temperature range from ambient temperature +5℃ to 100℃. It achieves ±0.5℃ temperature stability and ±0.3℃ temperature accuracy below 37℃, featuring fast heating and uniform internal temperature distribution.
• Equipped with a 20L large-capacity stainless steel inner tank and matched 304 stainless steel protective cover, the unit is corrosion resistant. Built-in over-temperature protection and LED digital display enable real-time clear temperature reading.
• The housing is made of Q235 plastic, dimension 667×349×357mm, net weight 16.2kg, 1000W heating power, standard 220V 50/60Hz power supply. It delivers simple operation and convenient daily cleaning & maintenance.

• Intelligent microprocessor temperature control delivers fast heating and stable constant temperature after reaching target value, with excellent temperature uniformity inside the water tank.
• Equipped with PT1000 high-precision temperature sensor, it achieves ±0.3℃ temperature accuracy and ±0.5℃ stability below 37℃, meeting requirements of high-precision thermostatic experiments like cell culture.
• Built-in over-temperature protection automatically cuts heating power when temperature goes abnormal, preventing dry burning damage to equipment and samples for safer lab operation.
• The inner tank and matched protective cover are made of stainless steel with corrosion resistance, supporting maximum heating temperature up to 100℃ for all kinds of aqueous solution experiments.
• LED digital screen clearly displays real-time water temperature inside the tank for easy reading.
• 20L large-capacity tank holds multiple sample vessels at the same time, ideal for batch incubation and parallel comparison tests.
• Robust and durable structure with smooth easy-to-rinse tank and standard spare parts, simple daily cleaning & maintenance to reduce long-term operating cost.

• L20WB-S is a versatile general-purpose laboratory thermostatic instrument for both basic routine tests and high-precision biological assays, widely applied in overseas university labs, third-party testing institutes and biopharmaceutical R&D workshops.
• The 20L corrosion-resistant stainless steel inner tank comes with a matched stainless steel cover to reduce water evaporation and stabilize internal constant temperature, ideal for long-duration continuous incubation experiments.
• The combination of PT1000 high-precision sensor and microprocessor control minimizes temperature error at low temperature range, ensuring repeatable test results for temperature-sensitive applications such as tissue culture, enzymatic reactions and strain incubation.
• Built-in over-temperature power-off protection automatically cuts heating power if temperature exceeds threshold to eliminate dry burning risks, prevent sample loss and lower lab safety hazards.
• LED screen displays real-time water temperature with an easy-to-understand control panel for quick operation by new staff. The smooth inner tank surface can be cleaned simply with clean water to reduce daily maintenance workload.
• 1000W high-power heating element delivers fast heating up to 100℃, meeting high-temperature pretreatment demands including sample digestion and boiling thermostatic extraction.
• Wide environmental adaptability allows stable operation in standard indoor labs at 10–40℃ and relative humidity below 80%RH, without extra temperature & humidity control accessories.

• Standard factory package includes L20WB-S water bath main unit, stainless steel protective cover, power cord and printed English operation manual. Overseas customers can carry out routine lab experiments right after unboxing without purchasing extra basic accessories.
• OEM private label customization service under Labcarta brand is available with custom exclusive brand LOGO printing and simple procedures, suitable for overseas instrument distributors to build their own laboratory instrument brands.
• The machine is packed in thick shockproof separate carton filled with inner buffer foam, which effectively resists extrusion and collision during long-distance ocean freight and air freight, greatly reducing the risk of equipment damage in cross-border transportation.
• The shipping lead time for in-stock orders ranges from 3 to 10 working days. Goods will be packed and delivered uniformly after order confirmation to shorten stock waiting cycle for overseas buyers.
• Multiple cross-border logistics options including sea freight, air freight and international courier are available. We can match the most cost-effective shipping solution according to customers’ total order quantity and required arrival time.
