Linear Shaker

Description:
Linear Shaker is a laboratory device designed for uniform mixing, agitation, and shaking of samples in test tubes, flasks, or bottles. It operates with a back-and-forth linear motion, ideal for pharmaceutical, biotechnology, chemical, and microbiology laboratories. This device ensures consistent sample agitation for a wide range of applications, including dissolution studies, liquid mixing, and microbial growth.

BOD incubator—standing for Biochemical (or Biological) Oxygen Demand incubator—is a specialized laboratory device designed for maintaining low and stable temperatures (typically between 5 °C and 60 °C) to support BOD testing, a key process in environmental water quality assessment. Unlike standard incubators that only heat, BOD incubators integrate both heating and cooling functions, making them essential in settings where precise, low-temperature control is indispensable.

Core Features & Design 1. Temperature Control & Uniformity

·         Range: Usually from around 5 °C up to 50–60 °C.  Standard BOD Test Temp: Commonly maintained at 20 °C, though requirements may vary based on sample type (e.g., freshwater vs. wastewater microorganisms).

·         Accuracy & Uniformity: Controllers (often PID with PT100 sensors) aim for ±0.2 °C to ±1 °C accuracy and uniformity.

2. Temperature Regulation Mechanisms

·         Heating: Via tubular or resistance wire heaters.

·         Cooling: Uses compressors with CFC‑free refrigerants, or Peltier (thermoelectric) technology in some models.

3. Air Circulation

·         Uniform Heat Distribution: Achieved via axial fans or forced-air convection systems.

4. Construction Materials

·         Inner Chamber: Typically stainless steel (SS 304), resistant to corrosion and easy to clean.

·         Outer Body: Powder-coated mild or cold-rolled steel; GMP models may feature full stainless construction.

·         Insulation: High-density PUF or glass wool between walls for thermal efficiency.

5. Doors & Viewing

·         Many models feature an inner glass door (sometimes magnetic-sealed) for observing samples without disturbing the internal environment. 6. Controls & Safety

·         PID Controllers: Provide accurate temperature settings; SV (set value) and PV (process value) are usually displayed. Some models include touchscreens, timers, or software integration. Safety Features: High/low alarms, over-temperature protection, and sometimes audible alerts.

7. Additional Functionalities

·         Illumination: Inside lighting (LED/fluorescent) often included, with optional timers.

·         Interior Power Outlets: Provide power for stirrers, shakers, or BOD Trak systems.

·         Mobility: Castor wheels allow easier repositioning.

·         Data Logging & Compliance: Some advanced units support USB, RS‑232, PLC, or 21 CFR Part 11 compliance
