Glass Fiber Syringe Filter 25mm 0.7μm Allpure Biotechnology 100pcs

Description

Product Overview

The Allpure Biotechnology glass fiber syringe filter is engineered to meet the demanding requirements of modern laboratory environments. With a robust 25 mm polypropylene (PP) housing, the filter provides a secure, chemically resistant enclosure that protects the delicate glass fiber membrane while ensuring a tight seal with standard syringes. The membrane itself is composed of high‑purity glass fiber, offering a uniform 0.7 μm pore size that balances fine particulate removal with a high flow rate, making it suitable for a wide range of applications from protein purification to HPLC re‑filtration.

Designed for versatility, the filter accommodates sample volumes ranging from 10 ml to 100 ml, allowing researchers to process both small analytical samples and larger preparative batches without changing hardware. The effective filtration area of 3.9 cm² maximizes throughput while maintaining low back‑pressure, which is essential for preserving the integrity of sensitive biomolecules during filtration. The glass fiber membrane exhibits excellent chemical resistance, handling both aqueous and organic solvents, and it can filter hydrophilic as well as hydrophobic solutions without degradation.

Usage

In routine laboratory workflows, the Allpure glass fiber syringe filter is employed as a pre‑filtration step to protect downstream analytical instruments from particulate contamination. Its high flow capability makes it ideal for rapid sample preparation before high‑performance liquid chromatography (HPLC), where maintaining sample clarity is critical for accurate peak resolution. The filter also excels in protein solution handling, where the 0.7 μm pore size effectively removes aggregates while allowing the target protein to pass through unhindered.

Beyond analytical chemistry, the filter is valuable in bioprocessing labs for removing cell debris from culture supernatants prior to purification steps. Its ability to filter both hydrophilic and hydrophobic solutions expands its utility to organic synthesis labs, where it can be used to clarify reaction mixtures before distillation or chromatography. The case of 100 filters provides a cost‑effective solution for high‑throughput environments, ensuring that each researcher has a ready supply for daily operations.

FAQ

What types of solvents can the glass fiber membrane tolerate?

The membrane is chemically resistant to a broad range of solvents, including water, methanol, acetonitrile, and many organic solvents commonly used in laboratory protocols. It can filter both aqueous and organic solutions without compromising structural integrity.

Can this filter be used for HPLC re‑filtration?

Yes, the 0.7 μm pore size is ideal for removing particulate matter that could clog HPLC columns, and the high flow rate ensures that re‑filtration does not introduce significant delays in the analytical workflow.

What is the maximum sample volume the filter can handle?

The filter is designed for sample volumes between 10 ml and 100 ml, making it suitable for both small analytical samples and larger preparative batches.

Is the filter compatible with standard 1 ml syringes?

Absolutely. The 25 mm diameter housing conforms to standard syringe fittings, allowing seamless integration with 1 ml, 5 ml, and larger syringes commonly used in laboratory settings.

What does the 30‑day after‑sales protection cover?

If the filter arrives damaged, does not meet the described specifications, or fails during normal use within 30 days of purchase, Allpure Biotechnology will provide a replacement filter or a full refund, ensuring customer confidence and satisfaction.
