New HPLC Column Chiller/Heater Ideal for Biomedical Samples at or Below Room Temperatures


Torrey Pines Scientific, Inc announces its new EchoTherm™ Model CO50 Programmable HPLC Column Chiller/Heater. It is ideal for chiral and biomedical chromatography where below ambient temperatures help preserve bioactivity.


The HPLC Column Chiller/Heater can be used for stabilising column temperatures from day to day at or near room temperatures for repeatable results. It has a temperature range from 4.0°C to 100.0°C readable and settable to 0.1°C. The PID control software regulates temperatures to ±0.2°C, even at ambient. The CO50 has a Stable Temperature LED that illuminates when the target temperature is stable to within ±0.2°C. The Peltier-based CO50 has a 5-program memory of 10 steps per program and the ability to repeat any program from 1 to 99 times automatically.


The CO50 holds columns up to 30cm long by ¼” or 3/8” diameter in mounting clips provided. Larger diameter columns can be used by removing the column clips that hold the smaller columns. The CO50 features RS232 I/O port for controlling the unit by a chromatograph, for programming gradients, and for data collection.


Also included are an injection counter, 30-day timer with user settable Auto-Off, and chamber drain for spills. The unit comes with a bench top universal power supply for use anywhere in the world, 3-wire AC line cord for the country of use, twelve month warranty and instruction manual. The Model CO50 is UL, CSA, and CE compliant.

Incubator Series offers Maximum Flexibility and Unparalleled Performance


Designed to meet the increasing demands of today’s laboratory and process facility, IP incubators from LTE Scientific offer maximum flexibility and unparalleled performance. These products are widely regarded to represent excellent value for money as they combine outstanding build quality. LTE is well known for the reliability and performance of its laboratory ovens and microbiological incubators.


Operating within a temperature range of 30 - 80°C, the range boasts extremely fast heat up times, almost undetectable over- shoot and superb accuracy. Set and actual temperatures are digitally displayed and to ensure sample safety, a manual reset over- temperature cut out (meeting IEC1010-2-010) has been incorporated.


Four models are available in each of the five sizes from 60 – 250 litres, with a choice of either fan circulation or natural convection, adjustable vent and a choice of PID control systems to suit most applications.


This ranges from single temperature set-point controller, through to a multi-program option, which stores up to eight multiple step cycles in the memory. This includes a ramp function which controls the temperature rise and fall rates. The programme can be stopped, repeated for a specified number of times or continue until interrupted, and in the event of a power failure the product has an automatic recovery function.

New Budget-friendly and Economical Chiller Range Announced


Many technical applications depend on a reliable cooling solution. Huber Minichillers and Unichillers are the ideal solution for environmentally friendly and economical cooling in laboratory and industry. There are several air and water cooled models available, with cooling powers from 0.3 to 20 kW. Efficient energy management in all Huber chillers ensures low operating costs and a quick return on investment.


The chillers are now available with the new OLÉ controller. The units combine state of the art technology with simple operation. OLÉ models are suitable for routine tasks in research and industry and are convincing as practice oriented basic equipment. They are equipped with USB and RS232 interfaces as standard and have a bright, large OLED display. A Pt100 sensor connection to display (not control) e.g. the process temperature is available as Option.


The compact Chillers have a premium stainless-steel casing and reach operating temperatures of -25°C to +40°C. The technical equipment includes an illuminated level indicator, as well as status symbols for pump, cooling and heating. All models are available with an integrated heating to extend the temperature range to +100°C.


All Huber Chillers are designed for non-supervised permanent operation at ambient temperatures of up to +40°C. The models are equipped with a circulating pump with 1 bar pressure for best flow rates. For applications with significant pressure loss, ‘P’ models with stronger pressure pumps (2.5 bar) are available.
