HPLC Mobile Phase Clarification & Microbiology Filtration

Xin Tester Glass Vacuum Filtration Apparatus (250mL – 1000mL)

Particulates and dissolved micro-bubbles in liquid chromatography mobile phases degrade column life and distort baseline detector signals. The Xin Tester laboratory vacuum filtration assembly is precision-engineered from 3.3 borosilicate glass to handle high-throughput solvent clarification, degassing, and particulate analysis. It provides an airtight seal around 47mm / 50mm microporous membrane filters. Explore our complete selections in the Lab Glassware catalog.

Three sizes of vacuum filtration apparatus: 250ml, 500ml, and 1000ml flasks with 300ml funnel

Precise frosted sand core head designed for 50mm filter membranes

Ground-Joint Alignment

The matching ground-glass rim between the graduated 300mL funnel and the fritted support base ensures uniform circular clamping pressure, preventing bypass leakage along membrane edges.

Spring-Action Aluminum Clamp

The heavy-gauge anodized aluminum hinge clamp enables rapid one-handed assembly and membrane replacement without requiring threaded collar rotations that can twist delicate filter discs.

Recommended Vacuum Support

Pair with an oil-free laboratory diaphragm pump for clean suction without oil mist. Filter membranes (Nylon, PTFE, MCE) are available separately.

FAQs

What materials are used in the Xin Tester® Vacuum Filtration Apparatus?

Our apparatus is crafted from premium 3.3 Borosilicate glass, which is highly resistant to chemical corrosion and thermal shock. This professional-grade laboratory glassware is designed with thickened walls to safely withstand the high vacuum pressure required for rapid suction filtration and distillation.

Which flask and funnel sizes are available in this set?

We offer three versatile variations to suit different laboratory scales: 250ml, 500ml, and 1000ml filtering flasks. Regardless of the flask capacity you choose, every set includes a standardized 300ml graduated funnel, providing consistent and reliable performance for all your solvent purification tasks.

What size of filter membrane is compatible with this apparatus?

The sand core filtration head is precision-engineered to work perfectly with standard 50mm diameter filter membranes. It is suitable for various types of membranes, including hydrophilic and hydrophobic options, ensuring effective filtration for diverse chemical and biological solutions.

Does the set come with everything I need to start filtering?

Yes, each Vacuum Filtration Apparatus set is an all-in-one professional kit. It includes a filtering flask, a 300ml graduated funnel, a high-strength aluminum alloy clamp for secure sealing, and a durable rubber tube for vacuum connection. You only need to provide your chosen filter membrane and a vacuum source.

Can this glass assembly withstand high temperatures?

Absolutely. Due to its high-quality borosilicate construction, the entire assembly is heat-resistant and can handle distillation tasks involving hot liquids. It is also autoclavable, allowing for easy sterilization between different laboratory experiments.

What is the benefit of the "Frosted Sand Core" head?

The frosted sand core design serves two purposes: it provides a stable, flat surface to support the 50mm membrane well, and it ensures a superior airtight seal with the funnel. This prevents any bypass of unfiltered liquid and maximizes the efficiency of the suction process.

Do I need a vacuum pump to use this filtration set?

While the apparatus is designed for vacuum suction filtration to significantly speed up the process, it can technically be used for gravity filtration without a pump. However, for professional efficiency and dealing with viscous fluids, we highly recommend using it with a laboratory diaphragm vacuum pump (such as our LV-15L model).

How is the product protected during shipping?

We understand that laboratory glassware is fragile. Every Vacuum Filtration Apparatus is meticulously inspected and packed in a heavy-duty foam cardboard box. This shock-resistant packaging ensures that your flask, funnel, and accessories arrive in perfect condition, ready for immediate use in your lab.
