MSI Enterprise is the sole authorised dealer of Hawach filter paper in India — qualitative and quantitative grades, extraction thimbles, and custom sizes for every filtration need.
We supply a wide range of filter paper grades suited to analytical, gravimetric, industrial and general-purpose filtration — available in standard and custom sizes, with bulk pricing for institutional buyers.
General-purpose filtration for routine lab work, education, and industrial applications. Ash content under 0.1%.
Low-ash-content grades for gravimetric analysis and precise quantitative chemical testing. Ash content under 0.007%.
Reinforced grades for demanding chemistry applications such as PbSO₄ and Fe(OH)₃ precipitate filtration.
Cellulose and glass fiber Soxhlet extraction thimbles for solvent extraction procedures.
Hawach grades are manufactured as direct equivalents to internationally recognized filter paper standards, so you can switch suppliers without changing your protocol.
