Qualitative Filter Papers Filter Papers & Membranes Cellulose filter papers Grade 1 Grade 1 standard filter paper is the most widely used filter paper for routine applications with medium retention and flow rate. Extended range of sizes includes 10 to 500 mm diameter circles and 460 570 mm sheets. This grade covers a wide range of laboratory applications and is frequently used for clarifying liquids. Traditionally, this grade is used in qualitative analytical separations for precipitates such as lead sulfate, calcium oxalate (hot), and calcium carbonate. Diameter mm Qty. Cat.

Filtration Devices Syringeless filters Syringeless Filters Whatman syringeless filters are preassembled convenient filtration devices for removing particulates from samples. They replace syringecoupled filtration devices with single disposable units. Whatman has made sample preparation easier, faster, and more efficient with its innovative product line of syringeless filters. Mini-UniPrep Syringeless Filters The Whatman Mini-UniPrep Syringeless Filters provide a faster and easier way to remove particulates from samples being prepared for High-Performance Liquid Chromatography (HPLC) and Ultra High- Performance Liquid Chromatography (UHPLC) analysis. In fact, Mini- UniPrep lets you prepare samples in one-third the time required by other methods. Mini-UniPrep is a preassembled filtration device consisting of a 0.4 ml capacity chamber and a plunger. The device can be used either manually or with a compressor unit. The multi compressor can process up to 6 samples at one time, further improving sample processing time and reducing the risk of hand stress. Product Cat.

Seed Testing Paper: Whatman seed testing papers are made from pure cellulose without any additives and do not contain any substances which could influence the growth of the seeds. The constant water absorption of the papers ensures the continuous provision of the required amount of water. The contrast of the color seed testing papers makes evaluation easier, particularly for seeds with fine white rootlets or under artificial light. Surface Protectors - Benchkote: Benchkote is an absorbent, impermeable material designed to protect laboratory surfaces against hazardous spills. The material features a high-quality, smooth, absorbent Whatman paper, which quickly absorbs liquid spills, and a laminated polyethylene layer that prevents flow through to the working surface. ph Indicator : Whatman offers a range of ph indicator and test papers made with traditional Whatman quality. These products combine ease-of-use with unsurpassed accuracy and consistency. The convenience of using indicator papers for the rapid determination of ph values has led to many applications in laboratories and industry. 77
