AF353 Haemoglobin content of blood (20 - 130 %)

Estimate Blood Haemoglobin Levels Using Harrison's Method Mark as favourite

Part Number 413530


  • Fast, Economical & Portable Visual Matching
  • Two-Field Vision for Accurate Results
  • Ability to Guarantee Constant Lighting Conditions

The Comparator 2000+ is an easy-to-use, entry level colour measurement system that compares the colour of the sample directly against the colour of glass in a disc. All you need to do is rotate the disc to get the closest result to the scale.

  • Direct Readings On-Site
    This method is particularly simple with low running costs since it employs undiluted blood and does not use any reagents. Furthermore, you do not require any power supply for operation. You simply run the blood directly into a special capillary blood cell and match the colour of the blood in a Comparator instrument with a series of precalibrated glass filters. The filters are housed in a pair of Lovibond® test discs: disc 5/8A covers the range 20 - 58% haemoglobin; disc 5/8B covers the range 64 - 130% haemoglobin (100% is equivalent to 14.6 g per 100 ml).
  • Fast, Economical & Portable Visual Matching
    The Comparator 2000+ is a flexible, modular system for Visual Colour Grading. Using a suitable comparator instrument and glass disc, you can quickly visually match the sample directly against the calibrated, colour stable glass standards.
  • Two-Field Vision for Accurate Results
    Lovibond® comparator instruments include an integrated prism which causes the sample and comparison fields to overlap, allowing enhanced colour discrimination and matching. The prism is ultrasonically sealed to prevent contamination of the optics. Each individually graded glass standard represents a discrete step on the measurement range (as opposed to a continuous graduation), aiding colour discrimination and allowing great accuracy of results.
  • Ability to Guarantee Constant Lighting Conditions
    An optional item for the Comparator 2000+ is the Daylight 2000 Lighting Unit. This is a standardised light source which guarantees you a constant lighting condition for accurate colour grading. This is particularly useful when the sample is very pale in colour. By using a Lovibond® lighting unit, you can confident of uniform lighting conditions for colour matching, 24 hours a day and irrespective of ambient lighting.
  • Extended Shelf Life
    The unique feature of Lovibond® test discs is that they incorporate coloured glass standards that are colour stable and not affected by UV light or extreme environmental conditions.
    Please note, we cannot guarantee compatability of discontinued Lovibond® Comparator 1000 disks with the Lovibond® 2000+ Comparator.
