A haemometer with a round tube is a device used to measure the haemoglobin content in blood. It uses a calibrated glass tube and reagents to determine haemoglobin concentration in clinical and diagnostic labs.

•   Material: Borosilicate glass tube

•   Capacity: 5 ml or 10 ml typically

•   Calibration: Graduated scale for haemoglobin levels

•   Design: Round, smooth tube for accurate measurement

•   Colour indicator: Paired with reagents for colorimetric comparison 

•   5 ml (miniature size for paediatric or low volume testing)

•   10 ml (standard size for general use)

 •   Round tube design for smooth flow and easy handling 

•   Manual haemometer: Visual comparison with colour charts

•   Semi-automatic haemometer: Photometric measurement with light sensors 

•   High-quality borosilicate glass for durability and chemical resistance

•   Reagents typically include sodium lauryl sulphate and iron salts

•   Medical diagnostic instruments

•   Haemoglobin measurement devices

•   Laboratory tools

 Available individually or as part of a kit with reagents and instructions 

 Measures haemoglobin concentration by mixing blood with reagents and comparing the resulting colour to standards.    

•   Simple and cost-effective

•   Quick results in minutes

•   Portable for use in clinics and fieldwork

•   Visual reading can be subjective

•   Limited to haemoglobin testing only

•   Requires careful handling and calibration 

•   Handle glass carefully to prevent breakage

•   Use correct reagents to ensure accuracy

•   Calibrate regularly and avoid contamination 

•   HSN 9018 : Medical and surgical instruments

•   HSN 901819  : Hemoglobinometers and related devices

•   Clean before and after use

•   Store reagents in a cool, dry place

•   Avoid direct skin or eye contact with reagents 

•   Clean with mild soap or alcohol-based solution

•   Dry thoroughly before storage

•   Autoclaving possible for non-chemical components 

 Used to check haemoglobin in animals to diagnose anaemia and blood conditions.

Useful in field and clinical settings for livestock and pets.

 Used in hospitals and clinics to assess patient haemoglobin levels,

aiding anaemia diagnosis and health monitoring.

What is a haemometer with a round tube?

   A device for measuring haemoglobin levels using a calibrated glass tube and reagents.

How does the round tube help?

   Ensures smooth flow and precise measurement of blood and reagent mixtures.

How are results read?

   By visual comparison to a colour chart or with a photometric sensor.

Can it be replaced by automated devices?

   Yes, automated analysers offer faster, more accurate readings but at higher cost.

How often should it be calibrated?

   Calibration should be done regularly, especially when reagents change or after long use.
