The Grant Range of Water Baths!
General purpose stirred bathsComply with IEC 1010 and Amendments 1 & 2; CSA 22.2
Economically priced general purpose baths which provide consistent temperature control over the range 0 to 99.9C and are suitable for a variety of applications where temperature uniformity and stability are important. Operation below room temperature is possible using an ancillary water cooling coil or refrigerated cooler.
Tanks are available in 6, 14, 22, 28 and 38 litre sizes and are made from stainless steel with an easytoclean, solvent resistant plastics outer case. Straight forward working instructions are printed on the side of the case.
The control units, which are mounted on a bridge plate, offer digital temperature setting and display and provide powerful stirring to ensure good temperature uniformity throughout the bath. Each bath can be fitted with a pump allowing temperature controlled liquid to be circulated through external apparatus. Control units are designed to allow dual position fitting so that the bath may be placed 'sideways' or 'endon' on the bench, as preferred.
The unit is protected by a user-resettable, fixed over-temperature cutout.

Baths with pump
Immersion Thermostats GrantImmersion thermostats from Grant with either analogue or digital temperature setting and electronic temperature control with Pt-1000 sensor. The thermostat units are housed in a fire-resistant plastics case and all immersed parts are either stainless steel or Ryton plastics and suitable for continuous operation in water at 100C or PEG at 140C.
The units are fitted with a pump for external circulation and over-temperature low liquid level protection is fitted. The thermostats are supplied with a clamp designed to lit onto existing tanks or water baths .

Thermostatic baths Grant Barrington rangeA new series of baths distinguished by modern, practical design and offering options to suit the most demanding user. The series offers five sizes of tank and a choice of control units with either analogue or digital setting. The tanks are formed in stainless steel and have glass fibre reinforced polyester moulded-in carrying handles. Operating instructions are printed clearly on the outside of the baths.
The smallest bath (6 litre capacity) utilises an immersion thermostat (see analogue type B20-585 or digital type B20-590) as a control unit, mounted on a stainless steel cover at one end of the bath. The four larger sizes of bath (which have a common width) employ a bridge control unit mounted across one end of the bath. These bridge control units are also available with either analogue or digital setting.
In the analogue control units the temperature is set using a knob with a scale graduated in C and fitted with a locking device. Fine adjustment may be carried out bv screwdriver over a ranqe of 1C.
In the digital control units a liquid crystal display has a resolution of 0 1 C and the temperature is set by pushing in the knob and turning until the desired value is displayed When the knob is released the actual bath temperature is displayed .
Both control units use a PT1000 sensor which has a greater output than the PT100 sensors commonly employed in comparable thermostatic baths. The most significant feature of the new control system is its long term stability
Both control units are fitted with adjustable over teTlperanlre protecbon an low liquid level float switches. Pumps for external circulation are also fltted as standard .
The Grant circulation system is unequalled for temperature uniformity throughout the bath. A propeller forces liquid down below the control unit, under a circulation tray and up at the far end. This produces a powerful horizontal flow throughout the whole of the working space and minimises the effect of the objects placed in the bath. The 6-litre bath does not use the circulation tray since its small volume renders this unnecessary. The 6-litre bath is supplied complete with flat stainless stee! lid with plastic handle. 1 he control unit fits onto a stalnless steel cover at one ena of the bath. This bath is intended primarily as a small circulator for pumping temperature controlled fluid around other apparatus The four other sizes of bath are supplied without lids and the bridge control units fit over one end of the bath. Glass fibre reinforced plastic lids are available as accessories for these models.
As with all Grant equipment, these baths carry a three year guarantee against faulty materials or workmanship.
