With the Agitated Glass Nutsche Filter from Xi'an Bioland Instrument, you can filter, wash, and dry all at the same time. It is made of high-quality borosilicate glass 3.3 and lets you see the whole process for both research and development (R&D) and pilot-scale production. This machine can work in full vacuum (-1.0 bar) to +1.0 bar pressure, and it can set temperatures from -60°C to +200°C. The built-in PTFE stirrer makes sure that the cake is washed and emptied evenly, and the double-jacketed design lets you control the temperature precisely. Our product has been made for more than 15 years and can process medicinal active ingredients, chemical intermediates, and high-purity compounds without any contamination.
A Agitated Glass Nutsche Filter is a commonly used biochemical instrument that combines the functions of a reactor and a filter. Mainly used in modern fine chemicals, biopharmaceuticals, scientific research experiments, etc. It can be used for crystallization, concentration, distillation, reflux, separation and purification. It is an ideal instrument for teaching, laboratory testing, pilot testing and production.

Certified Quality & Safety
We are licensed by CE, ISO, UL, and SGS. Each unit is safe and meets GMP/FDA standards. For extra safety, explosion-proof designs and PLC programming are available as options.
Unmatched Transparency
Because our glass is made of borosilicate, you can see crystallization, filtration, and cooling happen right in front of your eyes. There are no weak spots. Don't guess.
Chemical Compatibility
Acids, bases, and organic fluids can't get through PTFE and glass-covered routes. If there are no metals in the goods, it is more pure.
Flexible Customization
Need exact measurements? Different kinds of stirring? We offer OEM/ODM options that are made to fit your needs. Orders that are made to order ship in 30 working days, while regular units ship in 5–7 days.
Cost-Effective Direct Sales
When you buy directly from the factory, you save a lot of money on your investment. Get business-level gear without having to pay more for it.
Comprehensive Support
Every week, our R&D team uses pictures and films to keep an eye on production. Before shipping, you'll look over specific paperwork or set up a Factory Acceptance Test at our site.
One-Year Warranty
We back every Agitated Glass Nutsche Filter with a one-year quality guarantee and lifetime maintenance support.

Pharmaceutical Industry
That works great for making APIs, researching and developing peptide drugs, testing antiviral peptides, and making thymic peptides. The design of the glass keeps high-value chemical output from getting contaminated by other compounds.
Chemical Intermediates
Deals with strong acids in the production of fine chemicals. It is perfect for recovering catalysts, filtering pigments, and cleaning up unique chemicals.
Bioengineering
Helps with enzyme crystallization, protein separation, and the recovery of fermentation products, and visual tracking speeds up process optimization.
New Materials
Ultra-pure chemicals for semiconductors, nanomaterial filters, and battery material production are some of the things that this machine does.
Laboratory R&D
Allows testing on a small scale before full production. Researchers can change the settings of filters while watching the process change in real time.
International Standards
Our manufacturing facility holds CE and ISO 9001 certifications. All pressure vessels comply with PED (Pressure Equipment Directive) requirements.
Material Certifications
Every unit includes Certificates of Compliance for borosilicate glass and FDA 21 CFR 177.1550 certification for PTFE components.
Testing Protocols
GMP Compliance
Design, materials, and production processes meet Good Manufacturing Practice standards for pharmaceutical equipment.
Q: What's the maximum pressure my glass unit can handle?
A: Glass nutsche filters typically operate from full vacuum to +1.0 bar positive pressure. We install over-pressurization protection as standard. For higher pressures, consider our stainless steel models.
Q: Can I change filter media between batches?
A: Absolutely. The bottom plate uses a clamping ring mechanism. You can swap between coarse cloths and fine PTFE membranes (down to 1 micron) based on particle size requirements.
Q: How do you prevent seal failure with aggressive solvents?
A: We use dry-running PTFE bellows mechanical seals or double mechanical seals with inert barrier fluids. Regular integrity checks are part of our preventative maintenance schedule.
Q: Is drying really effective in a glass vessel?
A: Yes. The double jacket circulates hot fluid while vacuum removes moisture. The agitator ensures uniform heat distribution, preventing localized overheating and achieving consistent drying.
Q: What's included in your after-sales support?
A: Weekly production updates with photos/videos, detailed pre-shipment inspection documentation, optional Factory Acceptance Testing, one-year warranty, and lifetime maintenance service.
Q: Can you customize the agitator design?
A: Definitely. We offer anchor, paddle, turbine, and hydrofoil configurations. Stirring speed, temperature limits, and power requirements are all customizable to your process needs.
