GF/F: 0.7 µm
A glass microfiber filter membrane featuring the smallest pore size (0.6–0.8 µm) within its class; it is binder-free, offers a rapid flow rate, and possesses a very high loading capacity. The GF/F serves as the designated separation medium for solid waste leaching toxicity tests under environmental standards—a practice that remains in use to this day. Furthermore, the GF/F is the standard glass fiber filter membrane specified for "Determination of Chlorophyll in Water Quality Analysis." Thanks to its dense capillary structure, the GF/F is suitable for DNA adsorption and purification, as well as for filtering fine precipitated proteins. The GF/F is frequently paired with the GF/D to form a gradient filtration system, enabling the processing of large volumes of viscous or difficult-to-filter biochemical solutions, fluids, and nucleic acid samples. Disposable filtration funnels utilizing the GF/F are also available.
The specifications marked with "*" are regular products. It is recommended to purchase this type of specification model. The delivery time for other specifications is relatively long. Please contact customer service to confirm the delivery time when placing an order.The theoretical maximum tolerance temperature is 550 ℃ (there are many limitations, such as the temperature needs to gradually and uniformly rise, and baking should not exceed 1 hour when reaching the highest temperature). It is recommended to control the actual maximum temperature between 300-400 degrees Celsius.
