Applications and Experiments for the ESR Tube
The tube is filled with a prepared blood sample to the top of its 0–200 mm scale and held upright in an ESR rack. As the red cells settle, a clear plasma layer forms above them, and the height of that layer is read in millimetres after the set time to give the sedimentation rate.
- DMLT and BMLT haematology practicals: setting up and reading the ESR test in the 5-position ESR Rack.
- Timing the sedimentation period with a Mechanical Timer 60min, graduated 0 to 60 minutes.
- Clinic and hospital laboratories that run manual ESR measurements.
- Nursing and paramedical training: demonstrating how a sedimentation rate is measured.
Keep the rack level and free from vibration during the test, handle blood with gloves, and discard any chipped or cracked tube.

Frequently Asked Questions
What scale does the ESR tube carry?
The clear glass tube is graduated from 0 to 200 mm, so the settled plasma column can be read directly in millimetres. Its diameter is approximately 2.6 mm.
Which rack does the tube fit?
The tube suits an ESR rack with 5 positions. The ESR Rack in the range holds 5 tubes graduated 0 to 200 mm with a 2.6 mm internal diameter, and it can be quoted with the tubes.
Are the ESR tubes glass or plastic?
They are made of clear glass, which keeps the boundary between the red cells and plasma easy to see against the 0–200 mm scale during the reading.
Who supplies the Tube ESR?
The tubes are supplied by Science Lab Supplies in Ambala, India, which prepares quotations for tube quantities alone or packed with racks and other hospital lab equipment.
