Ohaus® Filter Glass Fiber, Pack of 200

Grade D Coarse porosity, fast flow rate, with a 2.7um size particle retention. Well suited for higher volume and repetitive laboratory filtering. Also ideally used as a general pre-filter to extend primary filter life. Glass microfiber filters are produced from 100% borosilicate glass microfiber without the use of binders or strengthening agents. Depth filtration categorizes filter media that traps particulate within the random matrix of fibers found within the thickness of the media. The efficiency rating of the filter is characteristic of the complex void space structure that develops ...

Disposable sterile Cellulose Acetate hydrophilic filtration media syringe filters are individually blister packed and feature Luer-Lok™ and pressure fitting. They are ultrasonically bonded for reliability and the filter media type is clearly inscribed on barrel. Excellent unit-to-unit and lot-to-lot reproducibility and consistency. The unique concentric funnel shaped barrel increases volume and decreases back pressure. Very low binding capacity for proteins. Cellulose acetate is nitrate-free making it suitable for groundwater & EPA ASTM's. Use for filtration under sterile conditions ...

Binder free glass microfiber used for Determination of Total Suspended Solids (Standard Method 2540 D. and EPA Method 160.2) and Volatile Suspended Solids.

The LabExact® PTFE Syringe Filter with integrated glass fiber prefilter is engineered for efficient filtration of challenging samples containing higher particulate loads. Featuring a 0.45 µm PTFE membrane, it provides excellent chemical resistance and is well suited for aggressive solvents, acids, and organic solutions. The built‑in glass fiber prefilter helps prevent premature membrane clogging, improving flow rates and extending filter service life. With a 25 mm diameter, it supports higher sample volumes and consistent throughput in demanding workflows. Supplied non‑sterile, this ...

LabExact 934-AH® glass microfiber filters are produced from 100% borosilicate glass microfiber without the use of binders or strengthening agents. Fine porosity, fast flow rate with a 1.5 um size particle retention. This material is the standard for suspended solids content and related measurements (Standard Methods 2540D and EPA Method 160.2). Also widely used in cell harvesting applications and RIA scintillation counting. Binderless borosilicate glass microfiber enables use up to 550°C. Depth filtration traps particulate within the random matrix of fibers within the thickness of ...
