Glass Vacuum Filter – Laboratory Vacuum Suction Filtration Device

Our Glass Vacuum Filter - also referred to as the Laboratory Vacuum Suction Filtration Device or Vacuum Glass Nutsche Filter - is engineered by Achieve Chem for laboratories that need more than basic solid-liquid separation. Unlike a standalone filtration funnel, this unit combines a fully transparent GG17 borosilicate glass vessel.

Beneath the vessel, a PTFE-glass bottom discharge valve allows clean, low-residue release of the filtered solid or slurry, while a sealed vacuum pipeline connects the assembly to an external vacuum pump to draw liquid through the filter medium. Because the main vessel is fully glass rather than metal, operators can visually track color change, crystal formation, and filtration progress in real time - a capability particularly valuable in R&D and quality-sensitive workflows. This **Glass Vacuum Filter** is therefore best suited to applications where combined stirring, reaction monitoring, and filtration need to happen within a single, visually transparent setup.

For facilities that instead require a dedicated, heavy-duty filtration system without a stirring function - for example, high-volume, repeated industrial filtration in harsher or more corrosive environments - Achieve Chem's Stainless Steel Lab Vacuum Filtration Unit, built around an all-metal funnel and frame with an optional 316L upgrade, is the more suitable alternative. The two units are designed to serve different stages and needs of a laboratory's filtration workflow rather than duplicating one another.

- Glass Vacuum Filter** with a fully transparent GG17 high borosilicate glass body, allowing real-time visual monitoring of the entire filtration.

- PTFE-glass bottom discharge valve for clean, low-residue material release after filtration

- Reinforced stainless steel support frame provides stable operation while preserving full glass visibility

- Broad chemical and thermal compatibility thanks to high borosilicate glass construction, suitable for a wide range of solvents and reagents

- Manufactured under an ISO9001 quality management system, with EU CE certification and a special equipment production license

- Customizable from 10L to 50L or larger to fit different laboratory and pilot-scale requirements

Our glass vacuum filter consists of a digital display speed controller, constant‑speed motor, mechanical seal stirring device, three‑port lid, GG17 high borosilicate glass vessel, and PTFE‑glass bottom discharge valve. Every component is designed for precision, durability, and easy maintenance.

- **Combined stirring-and-filtration reactions** - ambient-temperature stirring reactions that require in-process filtration without transferring the sample between vessels

- **Precipitate and crystal recovery in pharmaceutical R&D** - where visual confirmation of crystal formation and filtrate clarity supports process control

- **Solvent purification with visual verification** - operators can directly observe filtrate clarity during solvent or reagent purification

- **Cosmetic raw material processing** - filtration of extracts, essential oils, and botanical solutions where sample visibility helps assess color and purity

- **Environmental water sample analysis** - filtration and monitoring of water samples for contaminant testing

- Achieve Chem offers flexible customization for the Glass Vacuum Filter.

- Capacity options from 10L to 50L or larger, matching different lab-scale and pilot-scale needs.

- Funnel and flask material selection to suit specific chemical compatibility requirements.

- Custom lid port configurations, stirring speed ranges, and valve types based on process requirements.

- Complete turnkey systems paired with a vacuum pump and accessories for ready-to-use setups.

Q: What makes the Glass Vacuum Filter different from a standard vacuum filtration funnel?**

A: It integrates a digital-display, speed-adjustable stirring motor (0–600rpm) directly into a fully transparent glass filtration vessel, allowing stirring, reaction monitoring, and filtration to take place in one system rather than requiring separate stirring and filtration steps.

Q: Can I observe the filtration process while it's running?**

A: Yes - the main vessel is made of fully transparent GG17 high borosilicate glass, so the entire stirring and filtration process can be visually monitored in real time.

Q: What is the bottom discharge valve made of?*

A: The unit uses a PTFE-glass bottom discharge valve, designed for clean, low-residue release of filtered material.

Q: What capacity options are available?**

A: The standard range is 10L to 50L, with larger custom volumes available on request.

Q: How does this compare to Achieve Chem's Stainless Steel Lab Vacuum Filtration Unit?**

A: The Stainless Steel Lab Vacuum Filtration Unit uses an all-metal funnel and frame (with an optional 316L upgrade) and does not include a stirring function - it is built for dedicated, heavy-duty filtration in more corrosive or high-throughput environments. This **Glass Vacuum Filter**, by contrast, is designed for workflows that require integrated stirring and full visual monitoring of the reaction-filtration process. Choose based on whether your workflow needs combined stirring and observation (Glass Vacuum Filter) or dedicated, corrosion-resistant, high-volume filtration alone (Stainless Steel unit).
