Glass Plate Vacuum Filtration Set. Reliable lab glassware designed for everyday bench use. Built with quality borosilicate glass and precision manufacturing to handle routine lab workflows without fuss. A practical addition to any lab setup.

Eliminate Vacuum Leaks with a Matched Filtration Kit

Mismatched glassware often leads to dangerous vacuum leaks. A reliable glass plate filtration set solves this problem entirely. It removes the daily guesswork of pairing flasks from different suppliers. Finding the right rubber adapter for mixed brands is frustrating. Our matched combination saves you hours of experimental setup time. Every flask-to-funnel size ratio in this kit is pre-calibrated. The funnel seats securely inside the flask neck without tilting. We manufacture these sets using premium Boro 3.3 borosilicate glass natively.

This high-grade material meets strict global laboratory standards. You can review exact glass durability specifications at the ASTM International glassware hub. This matched system guarantees a tight seal for safe vacuum operations. It protects your valuable target compounds from accidental bench spills. Explore our complete Lab Glassware catalog to build a highly efficient workstation today.

1Pre-Calibrated Diameter Tolerances

Mismatched ground joints cause slurry leakage around the funnel rim frequently. This wastes valuable product and contaminates your pure filtrate. Mixing random brands causes severe cumulative manufacturing variance issues. A factory-paired set eliminates these physical connection risks completely. Every funnel outer diameter is machined to fit its paired flask perfectly. We maintain a strict ±0.5 mm tolerance during our manufacturing process. You will experience zero wobble or vacuum loss during operation.

2High-Speed Multi-Hole Glass Disc

Fine sintered discs clog quickly when filtering coarse particulate matter. Slow filtration ruins temperature-sensitive crystallization processes instantly. This funnel features a perforated multi-hole glass disc fused directly inside. It delivers a much higher flow rate than standard sintered G3 funnels. The perforated design keeps your liquid moving rapidly without blocking. It handles coarse precipitates larger than 50 μm natively. It is ideal for removing drying agents before fine polishing steps.

3Heavy-Wall Erlenmeyer Flask

Safety is paramount when working with active reduced pressure systems. Weak glass flasks can shatter inward unexpectedly during use. Our thickened borosilicate walls protect operators during continuous vacuum filtration securely. The conical flask body provides a very stable base for clamp mounting. The precision ground-glass neck accepts standard stoppers and addition funnels easily. You can build advanced reflux-filtration hybrid setups without any hassle.

FAQs

Q1: What is the difference between a glass plate filtration set and a sintered glass funnel?

A1: The key distinction lies in **filter media construction**. A glass plate filtration set uses a perforated glass plate disc with discrete drilled holes (typically 0.5–2 mm diameter) that provides high flow rates for coarse separations like removing magnesium sulfate drying agent granules, filtering hot gravity-fed solutions, or collecting large crystalline precipitates. A sintered glass funnel (e.g., our G3 series) uses a porous fused-glass disc with microscopic interconnected pores (15–40 μm for G3) that captures finer particles but clogs more quickly with dense slurries. Think of it as the difference between a colander (glass plate) and a coffee filter (sintered): use the plate for speed and coarse capture, use sintered for fines retention. Many labs keep both types on hand and select based on particle size distribution.

Q2: Can I use the Erlenmeyer flask separately from the funnel for other applications?

A2: Absolutely. The included Erlenmeyer flask is a fully functional Boro 3.3 conical flask with a precision-ground glass joint at the neck, identical in quality to standalone flasks sold individually. You can use it for titrations, reflux reactions (paired with a condenser on the ground-glass joint), solution storage, or any application that requires a chemically inert vessel with stable base geometry. The only consideration is that the flask interior may have minor etching marks from the original factory calibration process against its paired funnel — purely cosmetic and does not affect chemical performance whatsoever.

Q3: How do I choose the right flask-to-funnel size ratio for my typical workload?

A3: Follow the headspace rule: select a **flask capacity of 3× to 5× your expected total liquid volume** (including wash solvents). The funnel capacity should be roughly 25–40% of the flask capacity — this leaves enough room above the funnel rim for foam formation during vacuum application and for adding wash solvent without overflowing. For example, if you typically collect 200–300 ml of filtrate per run plus 150–200 ml of wash solvent, target total liquid volume ~500 ml, choose the **1000 ml flask + 250 ml funnel** combination (gives you 2× headspace margin). If you consistently overfill, upgrade one size larger rather than pushing the safety limit.

Q4: Is this filtration set compatible with my existing vacuum pump or aspirator?

A4: Yes, universally compatible. The Erlenmeyer flask features a standard side-tube nozzle (visible in the product image) sized to accept 6–10 mm ID vacuum tubing, which matches virtually every laboratory vacuum pump outlet, water aspirator connection, and house vacuum line barb. No special adapters required. For best practice, place a trap flask (empty Erlenmeyer or dedicated safety trap) between your vacuum source and the filtration flask to protect the pump from accidental liquid draw-through during pressure surges or foaming events.
