Jeio Tech – Shaking Water Bath (BS series)

The Jeio Tech BS series, Shaking Water Baths offers optimal convenience for the user with a wide range of capacity for various applications. They are designed from high-quality materials to resist metal oxidation. Reciprocal shaking in combination with a heating bath (PID microprocessor) provides precise & constant temperature control.

Ideal for:

  • General use – defrosting, cooling/warming liquids, temperature control of samples
  • Life-science – microbiological assays, tissue studies, cell cultivation fermentation, bacterial culture, biochemical assays, enzyme assay
  • Industrial – materials testing, corrosion testing
  • Food & beverage – extractions, food digestion

The water baths are supplied with a hinged gable cover and a spring wire rack.

Jeio Tech – Shaking Water Bath (BS series)

Key Features

• Temperature range from ambient +5°C to 100°C.
• Reciprocating shaking up to 180rpm while maintaining uniform temperature.
• Microprocessor PID control/temperature calibration/automatic tuning/automatic run.
• Seperate control keys for shaker mechanism allows the unit also to be used as a heating bath.

• Multiple LED displays (0.1°C and 1rpm resolution) for various values.
• Dual wait on/off timer modes (1 min. to 99 hr. 59 min.).
• Minimal shock to the samples thanks to the shaker’s gentle feature.

• Spring wire rack is easy to equip and the height of the rack is easily adjustable.
• Silent and anti-vibration BLDC motor.
• SUS 304 spring wire rack (two-tier rack with flexible crossed spring) provides various ways of glassware settings.

• Isolated design of agitator, heater, and sensor by a baffle plate to minimize the turbulence in the bath fluid and also to protect users and samples against direct contact.
• Complete safety protection system with warning alarms
