Review: Professional Glass Quality A+++ - Excellent packaging, Quality thick glass, for professionnel lab, high heat resistant since its for hot filtration during recrystallization. A+++ I recommend it. (Remember to buy a rubber seal to get good suction during vacuum for best results) Review: Does what i's supposed to. - Does what it's designed for but I got the feeling the tubing attached could have come off easier. I think this is due to the grooves on the connector being a little sharp. 4* out of 5* for a good product. ## Features - Used for pressure filtration; or to increase flow rate when some concentrated solutions are slow or difficult to filter under normal pressure - Made of durable borosilicate glass, offering excellent chemical resistance - Supports vacuum filtration and can withstand temperatures up to 450°C, ensuring reliable performance in demanding laboratory environments - Equipped with standard side-arm tubing connection, compatible with 8 mm I.D. vacuum hoses - Special notice: as this item is handmade, please allow an error range of 2-3 mm ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B076GPVFSJ | | Best Sellers Rank | 17,637 in Business, Industry & Science ( See Top 100 in Business, Industry & Science ) 5 in Lab Flasks | | Bottom Shape | Round | | Bottom shape | Round | | Brand | stonylab | | Capacity | 500 ml | | Country Of Origin | China | | Customer Reviews | 4.6 out of 5 stars 337 Reviews | | Graduation Interval | 500 Millilitres | | Graduation interval | 500 Millilitres | | Item Weight | 259 g | | Manufacturer | StonyLab Scientific | | Manufacturer Part Number | US-FilterFlask-500ml-Glass-1PK | | Material | Borosilicate Glass | | Material Type | Borosilicate Glass | | Model Number | US-FilterFlask-500ml-Glass-1PK | | Number of Items | 1 | ## Product Details - **Bottom shape:** Round - **Brand:** stonylab - **Capacity:** 500 Millilitres - **Graduation interval:** 500 Millilitres - **Manufacturer:** StonyLab Scientific - **Material:** Borosilicate Glass ## Images ![StonyLab Glass 500ml Heavy Wall Borosilicate Glass Filtering Flask, Bolt Neck with Tubulation, 500ml - Image 1](https://m.media-amazon.com/images/I/51JHqw6ciAL.jpg) ![StonyLab Glass 500ml Heavy Wall Borosilicate Glass Filtering Flask, Bolt Neck with Tubulation, 500ml - Image 2](https://m.media-amazon.com/images/I/51cNHcLv0fL.jpg) ![StonyLab Glass 500ml Heavy Wall Borosilicate Glass Filtering Flask, Bolt Neck with Tubulation, 500ml - Image 3](https://m.media-amazon.com/images/I/51o+0949JmL.jpg) ![StonyLab Glass 500ml Heavy Wall Borosilicate Glass Filtering Flask, Bolt Neck with Tubulation, 500ml - Image 4](https://m.media-amazon.com/images/I/61FNF8wTN0L.jpg) ![StonyLab Glass 500ml Heavy Wall Borosilicate Glass Filtering Flask, Bolt Neck with Tubulation, 500ml - Image 5](https://m.media-amazon.com/images/I/71XTQqG90eL.jpg) ## Available Options This product comes in different **Color, Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Professional Glass Quality A+++ *by G***D on 2 November 2021* Excellent packaging, Quality thick glass, for professionnel lab, high heat resistant since its for hot filtration during recrystallization.
