Brunel Haemascope DG & PC
Developed by ourselves the Haemascope is based on a research standard 100 watt high quality microscope that can be used for dark ground, phase contrast, or both. It combines excellent performance with excellent value. For dark ground work, the Haemascope uses a high end oil immersion objective with an internal iris (to stop flare) and and oil immersion dark ground condenser developed specifically for this purpose..
The analysis of whole blood preparations has obtained considerable popularity as a diagnostic and health monitoring tool in a wide range of alternative medicine fields. Dark ground and phase contrast techniques are commonly used. However blood cells are poor reflectors of light and have little by way of internal structure and therefore require very effective microscopy to obtain the the images that are needed. Standard biological microscopes are not good enough for this application. We have to stress this point as too often we find that referrals to us have bought microscopes that cannot produce the images needed.
There are several units on the market that purport to offer the solution, and some are more effective than others. In essence the system requires two essential elements. Firstly an effective illumination system of 100 watts quartz halogen (LED illumination is not suitable) and secondly top end quality optics. The correct balance between these two factors is essential to obtain the results needed to apply these techniques professionally and safely. It is not possible to purchase a suitable system cheaply, they just won’t do the job.
This is particularly important for dark ground analysis, which requires maximum illumination to overcome the fact that red blood cells are poor reflectors of light. A minimum of 100 watts is required for the light source, this is adequate providing the x100 objective is of good quality. Our own Brunel Haemascope has an excellent 100 watt quartz halogen light source. Some other units attempt to overcome poorer quality objectives by introducing excessive light by using fibre optic illumination introduced into the condenser of the microscope. This usually causes flare (which produces images that are unreal) and also an uneven field illumination, and generally tries to mask the fact that the x100 objective of the system is just not of sufficient quality for the purpose.
The objectives of any microscope system are the essential components necessary to achieve the results required. Failure to address this fact by attempting to overcompensate with unnecessary over illumination is a significant criticism of some units. For dark ground analysis, the Brunel Haemascope DG incorporates a high quality plan x100 objectives with an internal iris diaphragm. For phase contrast examination only the best will do, and the Brunel Haemascope PC offers an excellent phase contrast systems that deliver the results required.
Attention to detail is all important, and the types of slides, coverslips and even immersion oil can have a significant effect. Brunel Microscopes supply, with both its recommended systems, the best quality slides and coverslips of the correct thickness and our own formulated immersion oil.
Both systems offered by Brunel Microscopes address all these issues and provide the optical results required at a very competitive price.
Brunel Haemascope DG
Live cell analysis of whole blood from a finger prick site involves either dark ground and/or phase contrast microscopy. Brunel Microscopes have developed the HaemascopeDG dark ground video capture system which is available at an extremely competitive price -
Trinocular microscope with x4, x10, x40 and x100 (with iris diaphragm) objectives.
High specification oil darkground condenser
100 watt quartz halogen illumination system
The key to successful darkground analysis of whole blood rests with the illumination system and the quality of the x100 oil objective. The high wattage halogen Kohler illumination of the Brunel Haemascope has been developed specifically for this purpose, as has the x100 objective which is an excellent lens with an internal iris diaphragm. The two combine to give images that are the equal of units costing many times the price.
The Haemascope DG is preset to minimise the need for setting up the optics, simply make the slide preparation and follow a few basic instructions for instant results. Slides coverslips and all consumables for 200 tests included.

Brunel Haemascope PC
This unit consists of the same trinocular microscope stand which is equipped with a bright field/phase contrast system which allows easy transfer from conventional bright field microscopy to phase contrast presentation with full plan objectives. Patient involvement is not as relevant for phase examination and the system is available with or without the CCTV system. Trinocular microscope with x25, x40 and x100 bright field plan objectives; x40 and x100 phase contrast plan objectives, with phase telescope. Dual bright field/phase contrast condenser. 100 watt quartz halogen light source.

The examination of whole ‘live’ blood is an exacting procedure from the microscopy point of view. In brief there are two elements to the methodology. Firstly the choice and correct operation of the microscope system and secondly the interpretation of the images seen. Consistency of procedure is essential in this respect, and even the choice of microscope slides and coverslips will have a bearing on the quality of the results seen. Brunel Microscopes has 36 years experience in the supply of microscopes for all aspects of microscopy including whole blood analysis. This is reflected in the quality and performance of these units.
However when you have the right equipment you then need to know how to interpret the images. Live blood analysis is not a registered science and therefore is open to claims that are not backed by science fact -
