With the aluminum clamp, it provides a secure, firm and sturdy for apparatus. 1000ml Flask, 300ml Funnel The vacuum filtration apparatus comes with a 1000ml flask, a 300ml graduated funnel with stainless steel, a glass funnel, and an aluminum clamp. It is easy to read the number on the funnel. Filter Flask: 1000mL Graduated Funnel: 300mL Pore Size: 30-50μm Filter Paper: 47-60mm Fit It can fit for 47-60mm membrane filter paper. Pore Size With our 30-50μm, you can easy use it to filter. High Capacity Filtering Flask Due to our 1000ml filter flask, you can hold more liquid. Funnel 300ml is included. You can use it to measure. Review: Works great! - Works perfect. Wish I could buy the components separately, though. Review: Learn how to use it, then treat it well, and it will treat you well - This is a review for the QWORK 1000ml vacuum filtration assembly. It arrived packed well in molded styrofoam which can also be used for storage. It does not come with a vacuum pump or aspirator. There are six components: the beaker, the neck attachment with vacuum port, the screw on check valve with plastic hose barb, the funnel, the stainless steel lid, and the clamp. You will need vacuum grease for the ground glass joints which connect the beaker neck with the vacuum port. If you do not use grease there is a potential for the connection to "freeze" and it will not be able to be unstuck, resulting in one piece having to be broken off. A review complained about this happening to theirs, so this is not an idle worry. There is specific vacuum grease (from Dupont, I think) but an inert, food safe silicone grease can be used in its place. I use "Super Lube Silicone Dielectric Grease (Food Grade) Part No. 91003" which is available on desertcart, is cheap, and can be used for all sorts of other things as well. You want to apply two very thin lines on either side of the beaker neck, seat the other piece, and rotate until the grease coats the two joints uniformly. It can be wiped off before cleaning. The neck piece with the vacuum port contains a glass frit filter which can be used without filter paper if you want. However I recommend getting filter paper since it makes cleaning much easier, and you can filter finer particulates. I use the "Whatman 1001-055 Qualitative Filter Papers; 5.5 cm Diameter; Pore Size, 11µ" and it works well. If you do not use the filters, DO NOT try to filter out carbon, either from charcoal or activated carbon or any other source. It will be caught in the frit and is almost impossible to clean out (strong caustic acids are required which cannot be purchased by consumers). Also, do not use it to filter any strong sodium hydroxide solutions (lye) since this eats glass and can change the pore size of the frit filter. I found that grease is not needed between the neck and the funnel if it is fitted correctly. You must be careful with how you handle the assembly. For instance, there is no lip on the beaker neck, so if you grasp the beaker by the neck and try to move it, it can slip through your grasp and fall. Having the rest of the assembly put together makes this tempting because it looks to be solid, but only grease is holding everything together between the beaker and the rest of the assembly, and if you try to pick it up from the neck it will all fall apart. Don't do it. If you want to retain the filtered matter from the funnel, it is not difficult if all of the solvent has been removed, since the particulate will be retained enough from compaction that removing the funnel will not make it immediately fall out. However if there is any solvent in the funnel you want to remove, you will have a hard time doing it without siphoning it out the top, or doing some quick acrobatics flipping everything over quickly. Unclamping the funnel from the neck with the vacuum port will result in liquids immediately spilling out from the bottom of the funnel, since any filter paper and the frit is in the neck part. The plastic barb screws onto the vacuum port and contains a check valve, so that nothing can flow backwards into the assembly. This will keep a vacuum as long as you don't remove it and there is enough solution in the funnel to keep out the atmosphere. For the vacuum, you do not need anything strong. Vacuum pumps do not move much volume since they push out gas via compression. High flow rate pumps are not ideal. I am using a small air pump for an aquarium, with a hole drilled into the inlet and a 1/4" hose barb glued in. The one I use is the "Tetra Whisper Easy to Use Air Pump for Aquariums (Non-UL)" (the size for 10 gallon sized aquariums). The glass components are thick walled and well made, and fit together perfectly. Overall, do not expect vacuum filtering to be fast, clean, or easy -- but it is definitely much better than gravity filtering and this assembly will do the job. I have not tried any others, but this seems to be a great pick if quality is desired but money is tight. ## Features - EASY VACUUM FILTRATION: 1000 mL flask and 300 mL funnel enable quick liquid separation under controlled vacuum. - ACCURATE FITMENT: Accepts 42–60 mm membrane filters; not compatible with thick paper filters. - RELIABLE CONNECTION: Glass joint with metal clamp ensures leak‑free and stable operation under vacuum. - WORK RANGE: Performs best with pumps rated ≥3 CFM and vacuum up to 0.08 MPa (600 mmHg). - TEMPERATURE GUIDANCE: Borosilicate glass withstands ‑20 °C to 150 °C; avoid thermal shock or sudden cooling. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0822LDSC3 | | Best Sellers Rank | #86,525 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #4 in Lab Filtering Flasks | | Bottom Shape | Round | | Brand | QWORK | | Brand Name | QWORK | | Capacity | 1000 Milliliters | | Customer Reviews | 4.3 out of 5 stars 142 Reviews | | Global Trade Identification Number | 00781545590521 | | Item Weight | 2 Pounds | | Manufacturer | QWORK | | Material | Glass, Stainless Steel | | Material Type | Glass, Stainless Steel | | Model Number | WD3059 | | Part Number | WD3059 | | UPC | 781545590521 | ## Product Details - **Bottom Shape:** Round - **Brand:** QWORK - **Capacity:** 1000 Milliliters - **Material:** Glass, Stainless Steel - **UPC:** 781545590521 ## Images ![QWORK Glass Vacuum Filtration Set, 1000 mL Flask & 300 mL Funnel – 10 μm Pore for Lab Liquid Clarification, Sample Prep & Solvent Filtration - Image 1](https://m.media-amazon.com/images/I/61JO5He32SL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works great! *by B***N on August 28, 2025* Works perfect.
