19 Ovens, Furnaces & Heating Equipment New Ashing Furnace Introduced


Thermcraft’s newest release, the XSB Ashing Furnace, is designed for complete combustion of test samples. The XSB Ashing Furnace is Thermcraft’s latest solution for the combustion of test samples. With an 1100°C maximum operating temperature and a heated chamber volume of up to 40L, it provides ideal conditions for ashing petrochemicals, coal, food, plastics, and other hydrocarbons. The XSB boasts a uniquely low external temperature due to an air gap between the chamber exterior and actual furnace exterior. Inside you’ll find easily replaceable wound wire heating elements, but it’s not just the elements that can be swapped. All furnace parts come with lifetime availability, meaning your Thermcraft furnace will never become obsolete.


Safety features include a vertical lift door that ensures the hot insulation stays facing away from the operator, and a protective switch that interrupts power to the elements when the door is opened. Many other features come standard, and upgrades like profile programming, communications and data acquisition for the SmartControl can be added before or after purchase.


As for all Thermcraft standard products, new lab furnaces arrive fully assembled and ready to for connection to your power supply. But what’s truly unique is that delivery happens in as little as two weeks of your order placement. The XSB conforms to multiple ASTM and ISO specifications and with a uniformity of ±2°C over 9 distinct data points, it’s one of the most accurate lab furnaces on the market.


40577pr@reply-direct.com Measure and Control Flow Directly at the Temperature Control Unit


Huber Kältemaschinenbau offers a variety of measuring equipment for installation in the temperature control circuit in order to measure and control the flow rate. The flow rate can be displayed directly on the controller and can be requested and/or set through the digital interfaces (USB, RS232, LAN and optionally RS485, Profibus). It is also possible to control the flow rate using flow on an Unichiller or Unistat equipped with an integrated VPC bypass or external VPC bypass. The flow meters are available in different designs; depending on model and temperature control device. They cover flow rates between 0.2 and 750 litres per minute and working temperatures from -125 to +425°C.


The flow measurement devices can be used to complete basic tasks, such as determining kinetic/dynamic features of reaction syntheses and crystallisation, inspections of heat quantities and scale-up testing. Unistats can also be assigned. The new E-grade ‘Explore’ allows Unistats (only) to display or request the current system capacity (heating/cooling), as well as of the temperature differences, and is therefore perfectly suited to developing and optimising chemical processes.

PolyScience offers almost two dozen recirculating chillers designed to maintain bioreactors at the constant temperature required for optimal bacterial and yeast growth. A highly reliable and cost-effective alternative to expensive, inconsistent and wasteful tap water cooling, PolyScience Benchtop Chillers and 6000 Series Chillers help ensure maximum yield in the bioproduction of pharmaceuticals, antibodies and vaccines.


PolyScience Benchtop Chillers offer a compact and easy-to-operate solution for cooling bioreactors up to 10 litres in size, maintaining temperature with ±0.1°C stability and delivering cooling capacities as high as 1610 watts. Seven different models are available; all feature a space-saving design, large easy-to-read LED display and a choice of pumps.


For bioreactors larger than 10 litres, PolyScience 6000 Series Chillers are recommended. They also maintain temperature with ±0.1°C stability and feature large, dual displays that present temperature and pressure or fl ow rate simultaneously. These chillers are available with cooling capacities as high as 2900 watts, compressor sizes from ¼ to 1 HP, and positive displacement, centrifugal, or turbine pumps.


All chillers feature readily accessible, reusable fl uid and air fi lters, which are easily removed for cleaning, helping simplify maintenance and ensuring energy effi ciency.

Digital Water Baths Offer Exceptional Temperature


Control and Functionality PolyScience’s line of economical general purpose water baths combine exceptional temperature control with full-featured digital functionality and ease of operation. Designed to accommodate a wide variety of clinical and laboratory


applications, these versatile water baths maintain bath temperatures from ambient +5° to 99°C with ±0.1° stability and ±0.2°C uniformity. They are available with 2, 5, 10, 20, or 28 litre single chamber reservoirs.


In addition to precise temperature control, PolyScience Water Baths feature a digital temperature readout that displays both the actual bath temperature and set point temperature simultaneously, three user-defi ned temperature preset buttons for the quick selection of frequently used temperature set points and an integrated timer. Bath temperature can be displayed in either °C or °F. For added operational convenience, all models include a steeply gabled tilting cover that accommodates glassware of varying heights and permits easy loading and removal of samples while allowing condensate to drain neatly back into the bath. A high-clearance lid is available as an accessory for larger fl asks or bottles. Baths with a 10 litre or large reservoir are also equipped with a reservoir drain. All models come equipped with a diffuser tray.
