Incubators & Ovens LMS? Issue 6 | 2013? 19 Rotary Rocking and Rolling T he HTR range can be used in the heat treatment and analysis of sulphide ores and metallurgical slags, and the controlled calcination of mineral ores and limestone. F or years, New Brunswick CO2 incubators have provided researchers with a reliable and easy-to-use system for culturing cells. Continuing with this tradition, they released the S41i CO2 incubator shaker. This shaker is designed specifically for non-adherent cell culture applications. It combines precise temperature and CO2 control with one of the best laboratory shakers available. HTR rotary° reactor furnaces combine many of the advan tages of fluidised bed reactors with those of a rotary kiln. The sample is contained in either a 75mm × 100mm reaction chamber holding approximately 50ml or in the larger unit, a 150mm × 200mm 700ml reactor. These quartz vessels reciprocate backwards and forwards through an angle of 315°, at up to eight cycles per minute. Internal vanes within the reactor walls agitate the sample ensuring uniform mixing and heating throughout. Gas seals, a flow meter and control valve allow an inert nitrogen atmosphere to be maintained over the sample during heating. Any exhaust gases are vented into a removable stainless steel box that can be vented into a fume extraction system. Some of the customised HTR options include the replacement of the quartz glass reactors with Inconel reactors, modi­ cation for use with argon and gas fi safety, and detection systems for use with reducing gases. Carbolite routinely builds these furnaces for use up to 1600°C. These furnaces provide the capability to continuously process samples or even production quantities of material. Samples can be fed into the furnace using vibratory feeders or screw feeders. Designs are also available to introduce process and collect materials under modified atmospheric conditions. ?

It also has a built-in New Brunswick shaker. Combining their CO2 incubator and shaker technologies creates a highly stable environment for reliable cell growth. When it comes to high cell yields and viability, and overall reliability, there is no better solution. The S41i incubator shaker minimises the CO2 con­umption without compromising cell s growth and viability. Their performance tests show that it significantly reduces costly gas consumption, making it better for the budget and the environment. ?
