The hand-operated vacuum pump eliminates the need for a water source, vacuum aspirator, or electric pump, making the system portable and cost-effective. The rubber stopper is cut to securely hold the Buchner funnel, while the borosilicate glass filtering flask supports repeated laboratory use. The manual pump delivers a pumping rate of 15 mL per stroke and can displace up to 725 mL of air. A built-in valve allows controlled release of vacuum pressure. This complete kit is suitable for chemistry instruction, demonstrations, and routine lab filtration tasks.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eKey Features\u003cbr\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli data-start=\"2930\" data-end=\"2983\"\u003eManual vacuum pump requires no electricity or water\u003c\/li\u003e\n\u003cli data-start=\"2986\" data-end=\"3020\"\u003ePumping rate of 15 mL per stroke\u003c\/li\u003e\n\u003cli data-start=\"3023\" data-end=\"3054\"\u003eDisplaces up to 725 mL of air\u003c\/li\u003e\n\u003cli data-start=\"3057\" data-end=\"3097\"\u003eValve allows controlled vacuum release\u003c\/li\u003e\n\u003cli data-start=\"3100\" data-end=\"3147\"\u003eDesigned for vacuum filtration demonstrations\u003cstrong\u003e\u003cbr\u003e\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GSC International Inc.","offers":[{"title":"Default Title","offer_id":46229344616587,"sku":"GS-4400","price":63.51,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0339\/3863\/6939\/files\/4400FLASKVACUUMKT-Photoroom.jpg?v=1773849791","url":"https:\/\/uberbazaar.com\/products\/filtering-flask-vacuum-pump-kit-lab-vacuum-filtration-system-by-gsc-international","provider":"Uber Bazaar","version":"1.0","type":"link"}
