Montana Instruments Corporation announces the Cryostation Microscope, for high magnification physics experiments at 3 Kelvin!

Montana Instruments Corporation (Bozeman, MT), the world’s leading manufacturer of automated optical cryostats, announces the addition of the Microscope option to its closed cycle cryostat, the Cryostation™. Many low temperature material science experiments require high magnification optics to image the sample surface. Historically, this research has been limited to using objectives outside the vacuum space of the cryostats and dealing with the distortions of the vacuum window. This innovation allows user to position high quality optics near their sample without any intervening windows.

The system uses a 100X Zeiss quality objective with a working distance of 310 microns and a numerical aperture of 0.9, and can be outfitted with almost any vacuum compatible microscope objective.

A previous barrier to putting high quality objectives in the vacuum space of a low temperature system is that as a lens cools, its individual optical elements change shape, the optical performance degrades, and the lens may even crack. In order to prevent this damaging distortion, and to preserve the optical quality, a patent pending design maintains the lens at room temperature. By mounting the objective inside the temperature stabilized sample chamber, once the system reaches the target temperature, any drift due to temperature changes is eliminated.

The Cryostation has become a reliable workhorse for the low temperature research community. As a closed cycle cryostat, it doesn’t require costly helium for cooling, but uses a reliable refrigeration cycle cryocooler. The system is best known for its low vibrations of less than 5nm and its rock solid temperature stability of less than 10mK. Researchers appreciate the ease of access to their samples under test, both for setup and for optical access.

Pioneers in the world of cold science automation, Montana Instruments designs, manufactures, and supports cryostat systems around the world. Visit the company’s website at www.montanainstruments.com.

The Electrical Counter Promote The Advantages Of Elnur Storage Heaters

The Electrical Counter have built up an excellent range of products to be supplied directly via the internet from their excellent web site, the base of the business is as the name suggests, anything that the electrical trade might require usually, off the shelf. If the product required is not obvious on the web site then an excellent call service will establish whether and when it can be delivered. This is certainly the case with the Elnur Storage Heaters, which The Electrical Counter company is very pleased to supply from its standard in-stock store. This resurgent business in storage heaters has developed because of the inspired development of the latest Elnur Storage Heaters. These Elnur Storage Heaters are now very efficient in energy usage from a low cost electrical source and they come in a range of sizes from 1.7KW to 3.4 KW power rating and also in a range of manual or automatic controls.

The Elnur Storage Heaters are of a superb slim line design that fit very well in any standard room and the small size of the units mean that they do not take up the whole of the wall space. The controls are easily accessible and the units acne work as a stand-alone unit or fixed to link in with other storage heaters as part of a fully controlled central heating system. The Electrical Counter is delighted with the quality of the Storage Heaters and the complete range of manual and automatic units that are available which enable the installer such a wide range of options. The safety systems are such that the Storage Heaters have automatic safety power cut outs when the grills, where the heat is released, are covered with clothes or other items. The Electrical Counter supply Storage Heaters where there is an automatic control system on the heat input to the heat sink so that just the right amount of heat is input into the storage heater for later usage. Elnur have developed the range of Storage Heaters to meet all occasions and the sophistication levels are now so good that they heat input on the best units is controlled so that it takes account of the weather so that heat is not wasted in periods of warm weather or left short in periods of excessive cold. If this is added to a full central control system the maximum flexibility in heating control is possible, Hyco Water Heaters are also another great addition to the system in order to maximise your homes overall efficiency.

The Electrical Counter is pleased to note that these units fit extremely well in conditions where there is a surfeit of electrical power from a solar panel system where the daytime electricity is basically the property of the householder during the day and hence is free.

The market is ever increasing and the boiler fuel systems are not only suffering price rises from the energy suppliers but things like gas checks are now advised annually for house owners and are imposed by law on the house rental business. The Electrical Counter notes that the costs of each system when all the equipment costs, energy costs and service costs are taken into account are very close. The Electrical Counter welcomes any enquiries on the use of Elnur Storage Heaters.

Electrical Counter Now Can Supply Elnur Storage Heaters Of Great Versatility

It is fascinating how the increases and changes in technology can turn a system that seemed to have passed its heyday into a completely different and thriving system. The Elnur storage heaters systems are one of the most surprising elements in the distribution of energy used in the heating of household residences. Central Heating became just that, with a central boiler feeding a number of satellite radiators to supply heat throughout the house. Gas boilers became particularly cost effective due to the low price of gas compared to oil and electricity and bottled or tankered gases and the gas boilers have become very energy efficient units. Electrical Counter remembers when the storage radiator started as a pile of refractory bricks in a box which were heated by electrical heaters overnight and slowly released their heat as the cooled down. The system was effective to a certain level but temperature control and cost efficiency were limited.

The systems that Electrical Counter supply today have completely changed all this and the latest systems can be all singing and all dancing with a great temperature control and heat on demand. The heat input into the Elnur units which Electrical Counter supply is still carried out overnight to take care of using power in the low cost period that runs from about midnight until the early hours. The latest Elnur Heaters are excellently insulated with modern materials and heat losses from wastage are minimal. The control of heat release has now changed out of all proportion and the units are often fitted with the latest fan systems which control heat release but also allow a quick heat release. The days when a person comes home to a cold house and had to wait for hours to get warm have long since gone. The usage of a dynamic storage heater has now allowed the systems to be fitted to digital programmers so that the whole house can be warmed according to the demands of the users. This is a far cry from the system where the heaters were heated at night and slowly released the heat during the full day at a steady slow rate. The Electrical Counter systems encompass the whole house and the programming entails a full central heating system which can match the best gas heated systems without any of the waste gas products and flue problems associated with such units.
