The larger 100 ml volume suits protocols that require greater sample or standard volumes while remaining practical for routine laboratory glassware practice.\u003c\/p\u003e\n\u003c!-- lx-pdp-inline --\u003e\n\u003cp\u003eThis article is part of \u003ca href=\"\/en-be\/collections\/measuring-cylinders\"\u003eMeasuring cylinders\u003c\/a\u003e, in \u003ca href=\"\/en-be\/collections\/volumetric-glassware\"\u003eVolumetric glassware\u003c\/a\u003e.\u003c\/p\u003e\n\u003ch3\u003eKey features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePack size: 1 pc\u003c\/li\u003e\n\u003cli\u003eProduct type: Nessler cylinder\u003c\/li\u003e\n\u003cli\u003eMaterial: calcium soda glass\u003c\/li\u003e\n\u003cli\u003eForm: short\u003c\/li\u003e\n\u003cli\u003eCapacity: 100 ml\u003c\/li\u003e\n\u003cli\u003eWeight: 0,160 kg\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Marienfeld","offers":[{"title":"1 pc \/ 1 piece","offer_id":56186417676620,"sku":"TX38.1","price":22.2,"currency_code":"EUR","in_stock":true},{"title":"1 pc \/ 6+ pieces","offer_id":56186417709388,"sku":"TX38.1","price":21.09,"currency_code":"EUR","in_stock":true},{"title":"1 pc \/ 24+ pieces","offer_id":56186417742156,"sku":"TX38.1","price":19.98,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/4827\/7068\/files\/TX37-01-1000Wx1000H_d158230c-ad08-4c2d-9d79-d61c6b3b7f14.jpg?v=1766495002"},{"product_id":"nessler-cylinder-calcium-soda-glass-tx39-tx39","title":"Nessler cylinder, calcium soda glass, tall, 50 ml, 1 pc","description":"\u003cp\u003eNessler cylinder, calcium soda glass, is a tall laboratory measuring vessel with a nominal capacity of 50 ml for volumetric and visual comparison work.
