COD Digestion Tube
Product Code : EL-TT-10178
Lab Glassware Manufacturer manufactures and exports the COD Digestion Tube from its production base in Ambala, Haryana, in continuous operation since 1982, supplying school and college science laboratories, university and research departments, and export buyers that have recently included institutions in Ethiopia, Somalia and Djibouti — part of a wider base of enquiries from across the Horn of Africa.
Quick answer: A COD Digestion Tube is a thick-walled borosilicate glass tube used in Chemical Oxygen Demand (COD) digestion — heating a water sample with reagents in a COD digester block to measure organic pollutant load. Lab Glassware Manufacturer supplies these tubes in two sizes, 26 x 205mm and 39 x 205mm, to match common digester block formats.
COD Digestion Tube — Specification
| Parameter | Specification |
|---|---|
| Material | Thick-walled borosilicate glass, manufacturer-stated as mechanically resistant |
| Application | COD (Chemical Oxygen Demand) disintegration / digestion |
| Size 1 (O.D. x Length) | 26 x 205 mm |
| Size 2 (O.D. x Length) | 39 x 205 mm |
Why Wall Thickness Matters for COD Digestion
COD digestion heats a sample with strong oxidizing reagents at high temperature in a digester block, so the tube needs to withstand both thermal stress and chemical attack repeatedly across test runs. A thick-walled borosilicate construction is specified for this reason. Confirm which of the two O.D. sizes matches the digester block in use, since COD tubes are made to a specific block's well diameter and are not universally interchangeable.
Frequently Asked Questions
What is a COD Digestion Tube used for?
It is used in Chemical Oxygen Demand (COD) digestion, where a water sample is heated with reagents in a digester block to measure organic pollutant load — a standard water and wastewater quality test.
What material is this tube made from?
It is made from thick-walled borosilicate glass, manufacturer-stated as mechanically resistant to withstand repeated heating and chemical exposure during digestion.
What sizes are available?
Two sizes are available: 26 x 205mm and 39 x 205mm (O.D. x length). Confirm which matches your digester block before ordering.
Do you export COD Digestion Tubes outside India?
Yes, COD digestion tubes and related laboratory glassware are exported to institutional and distributor buyers outside India, with recent enquiries from Ethiopia, Somalia and Djibouti among other markets. Confirm destination country and packing requirements at enquiry stage.
