Grant Optima range of heating circulatorsGrant Instruments a world-renowned supplier of scientific, life sciences and data acquisition products, has worked in partnership with customers to develop a brand new range of robust and value-for-money heating circulators and accompanying baths to improve productivity in the modern laboratory. 

The sleek, user-friendly Grant OptimaTM range of heating circulators consists of four new models providing excellent temperature stability (±0.05 to ±0.01 ºC) and uniformity (±0.1 to ±0.05 ºC).  The Optima series is designed for use with Grant's five new stainless steel or three plastic baths and the five models in its refrigerated bath and circulator range. A clamp is also available to allow independent use of the Optima thermostats with any vertical sided tanks.

Emma Hewson, product manager at Grant Instruments, said: "We have worked closely with customers during the design, prototyping and development stage of the Optima range to ensure that we really understand the heating and cooling challenges of technicians and researchers in the modern laboratory. 

"As a result of this consultation, we have improved the design and usability features and built in more programmability, without compromising quality or value-for-money, so that the user can set up a simple or highly complex procedure and leave the equipment to do its job so that they can do theirs."

For example, Grant's advanced Optima heating circulators - the TX150 and TXF200 - feature a full colour screen with icon driven menus to facilitate fast and accurate setup, a USB interface for PC programming via Grant's LabwiseTM software or data logging, an integral pump for external fluid circulation plus numerous safety features, temperature profiling and control functions. For complex analytical procedures, including temperature probe calibration and quality control testing, the TXF200 stores up to 10 programs each containing 100 segments.

The four modular Grant Optima heating circulators work with any of Grant's stainless steel and plastic tanks. The five new stainless steel tanks (5, 12, 18, 26 and 38 litre) feature raised feet for retort stand access and optional insulated gabled hinged lid to improve energy efficiency and to prevent evaporation. The 12, 18, 26 and 38 litre baths include drain taps for easy tank emptying and cleaning. In addition, the dual-position bridge plate ensures visibility of the thermostat while optimising bench space. 

The three plastic baths (5, 12 and 18 litre) are double-walled for rigidity, are easy to clean and are available with optional flat stainless steel or curved plastic lids.

Furthermore, for precision cooling applications such as spectrophotometry and refractometry, the Optima circulators can be combined with five Grant refrigeration units (5, 12 and 20 litre) to provide a range of 18 models to cover basic through to sophisticated needs.

The new Optima circulators, baths and refrigeration units are built to last and are manufactured in the UK under ISO9001:2008 using only the highest quality materials.  All products are covered by Grant's comprehensive 3-year warranty, which can be extended to a class leading 5 years.

"We believe that our modular range of heating circulators, baths and refrigeration units meets the needs of the modern laboratory in terms of functionality, programmability, performance and price," added Emma Hewson. 

The Grant OptimaTM series of heating circulators are part of Grant's comprehensive range of scientific products. This includes water baths, block heaters and coolers, baths/circulators and re-circulating chillers, and under the Grant-bio brand, thermoshakers, rockers, rotators and shakers, centrifuges and vortex mixers.
