Professional Microscopes

The Binocular model is recommended for people who require the performance of a professional microscope at a very realistic price. It has a 6volt, 20 watt quartz halogen illumination with rheostat control for optimum illumination. The field lens has integral daylight blue filtration. Like our monocular models, it comes with a mechanical stage and vernier for fine slide adjustment. Specification includes x 10 wide field eyepieces and x 4, x 10, and x100 achromatic objectives with numerical apertures of 0.1,0.25,0.65 and 1.25 respectively.

These professional microscopes come complete with carrying case and starter pack of slides. They have a range of 3 magnifications to suit all requirements. The Monocular comes with its own mechanical stage and slide holder to provide the necessary fine adjustment to slide movement and also comes complete with its own aluminium case. Magnification range x 50 - x 800. Also now features inbuilt lamp for specimen illumination.  As if that's not enough you also get a fish parasite identification kit thrown in!  The identification Kit contains: slides, cover slips, mountants, stains, specimen tubes, gill swabs, skin scrapers, pipettes and step by step instructions. No previous experience of microscope use or slide preparation required.  Both units utilise spring loaded front lenses and have both coarse and fine adjustment for optimum focus.

We also now offer a mini digital video camera that fits into the viewing eyepiece of any of our microscopes, whether monocular or binocular.  The minicam is connected directly to an external USB port of any PC or Laptop operating Windows 98 (second edition) and above - N.B. not suitable for Windows 95 or 3.1. The cameras come complete with software, transformer and USB connection lead.

Professional Digital Water Testing system.

At last, we are able to offer our customers a truly professional water testing system.

The Palintest portable photometer system is a sophisticated and very accurate device which enables the koi keeper to precisely monitor the condition of the pond water.

The instrument uses digital colourimetry, long recognised as the most accurate method of determining the levels of many common and some not so common substances that may be present in pond or fresh water supplies.

Digital colourimetry is the method used by water companies up and down the country to accurately monitor water conditions and this technology has now been incorporated into a range of portable instruments.

But not only is this instrument extremely accurate, as it utilises a number of different light wavelengths , it can monitor  up to 37 different water parameters, including aluminium, copper, zinc, phenols, chlorine, Chloramine, and phosphate as well as the basic necessities of ammonia,  nitrite and pH. 37 different tests performed by one instrument, and it does not matter if your pond water is cloudy, green or contains medications, since the instrument calibrates every test sample against your pond water first.  No more visual interpretation of colour - no possibility for errors.

The new 7100 photometer now automatically selects the correct wavelength and displays the results in mg/l directly on the large LCD display

To demonstrate the accuracy of this unit, it can measure ammonia levels in water down to 0.01 mg/litre, and it will register the presence of this and many other pollutants whilst a normal test kit tells you the water is safe.

Without doubt the most accurate and flexible water testing system available to the koi keeper anywhere!  A bold claim - but one which is easy to demonstrate.

We all invest considerable sums in our koi, and we all know that the most important single factor in keeping our koi healthy is water quality. Now for the first time, koi keepers everywhere can accurately and precisely monitor virtually all of the important water parameters which really matter .

This instrument could be the best investment in the koi hobby you could ever make.

The cost?  £695.00 including a starter pack of 20 Ammonia, Nitrite, Chlorine and Chloramine tests.

Price includes next day delivery.

Test your tap water, we know you won't be surprised at what you find - but, test the output from your cartridge water purifier - we think you might be surprised at what you find - whatever the claims!

 

The system comprises a digital photometer, six glass test tubes and dilution tube in a moulded plastic carrying case and comes complete with an extensive operating manual explaining the technology, test methodology for each chosen parameter and detailed instructions for each test. Reagents sold separately

Direct reading colourimeter with automatic set-up and reading

Bacteria Testing Dip slides single test £4.95

Dip test slides provide a very simple but effective method of determining the levels of bacteria in your pond.  One of the main causes of disease in our koi ponds is overstocking leading to very high bacteria levels,  especially in warmer water.  Minor damage on koi can then quickly become infected and the koi population become much more vulnerable to bacterial disease when the bacteria count is high.

In the slides pictured, the one on the right is unused, whilst the one on the left shows a high bacteria count after culturing at 30 deg C for 36 hours.

These dip slides come with complete instructions for use and are designed to detect all aerobic bacterial populations.
