Supplier: Cytiva

Whatman Grade 4 Qualitative Filter Papers are a standard grade, high flow rate filter paper. They are useful in qualitative analytical separations when fast flow is required and the collection of fine particles is not critical.

Supplier: Cytiva

Membranes are made from pure cellulose acetate, making them ideal for biological and clinical analysis, sterility tests, and scintillation measurements. Filters exhibit very low protein binding capacity and are hydrophilic, making them suitable for aqueous and alcoholic media. The cellulose acetate membranes have improved solvent resistance, particularly to low molecular weight alcohols, and increased heat resistance. The membrane filters exhibit high physical strength and can be used up to 180°C (356°F), making them suitable for hot gases and allowing them to be sterilized by all methods without sacrificing the integrity of the membrane.

Supplier: Cytiva

Whatman Grade 1 Qualitative Filter Papers are the most widely used filter paper for routine laboratory applications, qualitative analytical separations, and clarifying liquids. They are the standard grade cellulose filter papers for medium flow rates.

Supplier: Cytiva

For determining the type of causal agent of infectious diseases and for checking their sensitivity to antibiotics and chemotherapeutic agents in vitro by means of the inhibition zone determination method. The antibiogram allows rational and selective chemotherapy. The test disks are coated with chemotherapeutic agents, placed on the inoculated nutrient agar and incubated. The size of the inhibition zone is a measure for the effectiveness of the substances.
