Constant Temperature Ice Box

The Laboratory Water Bath (DWB20-S) is a digital benchtop water bath with 20-liter capacity, designed for precise temperature-controlled incubation of clinical samples, reagents, and diagnostic test preparations in clinical diagnostic and research laboratories . With a temperature range from ambient +5°C to 99.9°C and temperature control accuracy of ≤±0.5°C, this water bath provides stable, uniform heating for clinical chemistry, immunology, microbiology, and molecular diagnostics workflows .

For the clinical laboratory scientist and medical technologist, the DWB20-S supports enzymatic assay preparation for liver function tests (ALT, AST), cardiac biomarkers (CK, LDH), and other enzyme-based diagnostic assays . It provides precise temperature control for ELISA and immunoassay incubation in infectious disease and autoimmune testing, sample thawing and reagent warming for coagulation studies (PT, PTT), and microbiological culture media warming for bacterial growth and antimicrobial susceptibility testing .

The DWB20-S features a corrosion-resistant stainless steel tank, microprocessor-controlled digital interface with PID temperature regulation, programmable timer (0-99 hours 59 minutes), and over-temperature protection for sample safety . The insulated lid minimizes heat loss and evaporation, while the drain valve facilitates easy water changes and tank cleaning .

For the patient undergoing diagnostic testing for myocardial infarction, hepatitis, autoimmune disorders, or bacterial infections, the DWB20-S's precise temperature control ensures accurate enzymatic assay results, reliable immunoassay detection, and consistent culture-based identification—supporting appropriate treatment decisions and optimal clinical outcomes .

The Pro Thermostatic Ice Box(CT4) is a compact, microcomputer-controlled benchtop cooling device that maintains a precise 4°C environment using high-efficiency Peltier technology, designed for temperature-sensitive sample preservation in clinical diagnostic and molecular biology laboratories .

Operating with a fixed 4°C setpoint, the CT4-Pro achieves rapid cooling from room temperature to 4°C in ten minutes or less, with temperature control accuracy of ±0.5°C and uniform thermal distribution across the cooling surface . The Peltier thermoelectric cooling system eliminates the need for wet ice, dry ice, or refrigerants—providing a contaminant-free, environmentally friendly benchtop cooling solution for sensitive biological samples .

For the molecular biologist and clinical laboratory scientist, the CT4-Pro supports DNA amplification product storage, pre-denaturation cooling for electrophoretic samples, serum coagulation protocols, and enzyme/reagent preservation during experimental workflows . The magnetic adsorption interchangeable cooling blocks accommodate various tube formats including 0.5 mL, 1.5 mL, 2 mL, 5 mL, 15 mL, 50 mL tubes, PCR plates, and ELISA plates, with tool-free module changes for workflow flexibility .

The CT4-Pro features multi-color LED status indicators providing real-time operational feedback (Red: cooling, Green: stable), built-in temperature deviation calibration for long-term accuracy, and continuous operation capability for extended laboratory procedures . The compact design (200 × 235 × 120 mm) and lightweight construction (3.3 kg) minimize benchtop footprint while delivering reliable cooling performance .

For the patient undergoing molecular diagnostic testing, genetic analysis, or infectious disease screening, the CT4-Pro's stable 4°C sample preservation ensures nucleic acid integrity, enzyme activity, and specimen quality—supporting accurate diagnostic results that guide appropriate treatment decisions across clinical chemistry, molecular diagnostics, and blood banking applications.
