Sizes: XB2, XB3, MXB6, MXB14 and MXB 22 litres

design features

safety
MXB6, MXB14 and MXB22 litre baths have dual safety features, for overtemperature and low liquid level

Ultrasonic - ultra-efficient
Piezoelectric transducers emit continuous alternating pressure through the liquid in the bath. The waves of high and low pressure cause bubbles to form, to increase in size and then to collapse violently. This process, called cavitation, acts on any object placed in the bath.

The gentle scrubbing action provides consistently quick and thorough cleaning. Cavitation works wherever an object is in contact with the liquid, cleaning even the most intricate and fragile objects inside and out. Ultrasonic cleaning gives a high standard of cleanliness in a fraction of the time required by conventional cleaning methods. It is also safer than manual cleaning if there is any danger of contamination or infection.

Ultrasonic action is also used to de-gas liquids before use in chromatography, to prevent cavitation in high pressure pumps, and to modify reactions in sonochemistry, such as inducing rapid crystallisation of materials.

Technical Information

Grant Universal SUB Series

One of the world's best-selling range of water baths, the Grant SUB series of universal water baths provides good temperature stability for a wide range of routine laboratory applications.

Grant Economy JB Series

Grant Water Baths Digital High Performance GP200 Series

The Grant Optima™ GP200 series of digitally controlled stirred water baths and circulators provides outstanding performance for routine and sophisticated applications requiring accurate temperature control up to a maximum of 200ºC.

Grant GP200 series systems combine the powerful and versatile Grant Optima™ GP200 digital immersion thermostat with a choice of three economy plastic (P) tanks or five stainless steel (S) tanks with different capacities.

The Grant GP200 immersion thermostat incorporates Intelligent Control Optimisation™ (ICO) for adaptive intelligent PID temperature control and includes a powerful integral pump, making GP200 systems suitable both for immersing samples and circulating temperature controlled fluid to external devices. The temperature range and heater power are automatically limited according to the liquid type selected.

The GP200 control unit has a host of powerful and convenient programming features for optimum application flexibility. These include a convenient heater timer for early starts/late shutdowns, two programmable relays for switching external devices on/off, option for remote temperature monitoring, RS232 interface for PC communication and data collection, and memory capacity for five programs of up to 30 segments each.

• Dual display: bright LED for temperature display plus 2-line 16 character LCD for easy programming
• Twin heaters, 2kW heater power for fast heat up
• Pt1000 external probe socket for remote monitoring
• Powerful integral pump with multi-stage variable flow rate, maximum flow 21L/min
• Variable high and low temperature alarm settings - configurable to switch relays
• Choice of 5 operator languages
• Optional Labwise™ PC software for program set-up, data logging and real-time graphing
• Maximum cooling/heating range (dependent on tank size): ambient +5 to 99ºC with plastic (P) tank, or -15 to 200ºC with stainless steel (S) tank
• Stability ± 0.005ºC

Note: Alternatively, the Grant Optima™ GP200 immersion thermostat can also be used to regulate the temperature in vessels other than Grant tanks. Such vessels must have vertical sides and a maximum wall thickness of 35 mm for rectangular tanks, 30 mm for circular tanks (300 mm diameter) and a capacity of up to 50 litres. The control unit is attached to other vessels by means of a clamp.

Grant Refrigerated Thermostatic Bath Model GD200 R series - High Performance

The Grant Optima^TM GP200 series of digitally controlled refrigerated baths and re-circulators provides outstanding performance for routine and sophisticated applications requiring accurate temperature control in the range of -47 to 100°C.

Grant GP200 series refrigerated systems combine the powerful and versatile Grant Optima™ digital immersion thermostat GP200 with a choice of five rugged stainless steel refrigeration units with different facilities and working volumes.

The GP200 immersion thermostat incorporates Intelligent Control Optimisation^TM (ICO) for adaptive intelligent PID temperature control and includes a powerful integral pump, making GP200 series refrigerated systems suitable both for immersing samples and circulating temperature controlled fluid to external devices. The temperature range and heater power are automatically limited according to the liquid type selected.

The GP200 control unit has a host of powerful and convenient programming features for optimum application flexibility. These include a convenient heater timer for early starts/late shutdowns, two programmable relays for switching external devices on/off, option for remote temperature monitoring, RS232 interface for PC communication and data collection, and memory capacity for five programs of up to 30 segments each.

• Dual display: bright LED for temperature display plus 2-line 16 character LCD for easy programming
• Twin heaters, 2kW heater power for fast heat up
• Pt1000 external probe socket for remote monitoring
• Powerful integral pump with multi-stage variable flow rate, maximum flow 21L/min
• Operating setpoint plus 3 adjustable preset temperatures for convenience
• User calibration facility for optimum accuracy at the required operating temperature
• Variable high and low temperature alarm settings - configurable to switch relays
• Visual and audible alarm - alert you when your attention is required
• Choice of five operator languages
• Choice of five refrigerated (R) tanks with different facilities, working volumes and cooling capacities
• Cooling/heating range: -47 to 100°C (dependent on refrigeration unit selected)
• Stability ± 0.1°C

Note: The refrigeration unit can be switched off independently of the thermostat to allow heating only applications. All the refrigeration base units can be used up to a maximum temperature of 100°C.

Grant Refrigerated Thermostatic Bath Model GD120 R series - digital control

The Grant Optima™ GD120 R series of refrigerated baths and re-circulators with digital control provides excellent value for money for more demanding applications requiring accurate heating and cooling in the range of -20 to 100°C.

Grant GD120 series refrigerated systems combine the versatile Grant Optima™ digital immersion thermostat GD120 with a choice of five Grant refrigerated stainless steel tanks.

The GD120 immersion thermostat incorporates Intelligent Control Optimisation (ICO)™ for adaptive intelligent PID temperature control and includes a powerful integral pump, making GD120 series refrigerated systems suitable both for immersing samples and circulating temperature controlled fluid to external devices. It includes a convenient timer function for reaction timing and a variable high temperature alarm setting. The temperature range and heater power are automatically limited according to the liquid type selected.

• Simple-to-use rotor plus two keys provide access to the interactive interface for fast, accurate set-up
• Clear digital display for instant reassurance - easy to read from a distance
• Visual and audible alarm - alert you when your attention is required
• Operating setpoint plus 3 adjustable preset temperatures for convenience

Accessory options for the Grant Optima GD120 R series

Accessory vertical turbine pumps

Required only where the application demands a higher pressure than that delivered by the GD120 internal pump to maintain flow. Note: When an accessory pump is fitted, the available working area is reduced.

Grant accessory pumps feature a unique low noise, compact design which produces high pressure with low heat input to the liquid.

Supplied with pipe connections and special lid for fitting to tank, pipe bore 12.7 mm.

VTP1 - max. pressure 1000 mbar, max. flow 9 L/min
VTP 2 - max. pressure 1650 mbar, max. flow 12 L/min
