Supplied as 1 pc and weighing 0,280 kg, the flask forms part of the Rotilabo® labware line from manufacturer ROTH SELECTION and is intended for chemistry, life-science, and educational laboratories that standardise on NS45\/40 joints. Flat-bottom flasks with ground glass joints are frequently chosen for synthesis, solvent handling, and intermediate storage when both joint compatibility and bench stability matter. Clear glass construction supports visual monitoring of contents, colour changes, and phase behaviour during processes. Suitable for laboratories seeking a reliable 1000 ml jointed flat-bottom vessel for everyday experimental work.\u003c\/p\u003e\n\u003c!-- lx-pdp-inline --\u003e\n\u003cp\u003eThis article is part of \u003ca href=\"\/en-be\/collections\/flat-bottom-flasks\"\u003eFlat-bottom flasks\u003c\/a\u003e, in \u003ca href=\"\/en-be\/collections\/beakers-and-flasks\"\u003eBeakers \u0026amp; flasks\u003c\/a\u003e.\u003c\/p\u003e\n\n\u003ch3\u003eKey features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePack size: 1 pc\u003c\/li\u003e\n\u003cli\u003eBrand: Rotilabo®\u003c\/li\u003e\n\u003cli\u003eProduct type: Flat bottom flask with standard ground joint\u003c\/li\u003e\n\u003cli\u003eCapacity: 1000 ml\u003c\/li\u003e\n\u003cli\u003eGround joint: NS45\/40\u003c\/li\u003e\n\u003cli\u003eWeight: 0,280 kg\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Carl Roth","offers":[{"title":"1 pc \/ 1 piece","offer_id":56184337596748,"sku":"NT64.1","price":56.55,"currency_code":"EUR","in_stock":true},{"title":"1 pc \/ 6+ pieces","offer_id":56184337629516,"sku":"NT64.1","price":53.72,"currency_code":"EUR","in_stock":true},{"title":"1 pc \/ 24+ pieces","offer_id":56184337662284,"sku":"NT64.1","price":50.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/4827\/7068\/files\/NT59-1000Wx1000H_b5798fd0-f4d2-4031-b44c-df77b12f43b6.jpg?v=1766492518"},{"product_id":"rotilabo-flat-bottom-flask-nt65-nt65","title":"Rotilabo®flat bottom flask, w. stand. ground joint, 2000 ml, NS29\/32, 1 pc","description":"\u003cp\u003eRotilabo® flat bottom flask with standard ground joint is a laboratory glass vessel intended for larger-volume heating, reaction, and handling tasks that benefit from a stable free-standing base.

The flat bottom gives a stable free-standing stance on the bench, suited to high-volume preparation, bulk holding of liquids and transfer tasks where a round-bottom flask would need continuous external support. The 10000 ml capacity addresses scale-up and stock-solution work within a conventional flask form. Supplied as 1 pc at a weight of 4,430 kg, the flask belongs to the Rotilabo® range from manufacturer ROTH SELECTION. Its heavy duty rim reinforces the upper section for safer pouring, closure and movement of a large filled vessel, while the narrow neck supports more controlled filling and a smaller open surface than wide-mouth containers of similar volume. Stated height and capacity aid layout of storage, hoods and handling routes for oversized glassware. In laboratories that combine chemistry, media preparation and general wet processing, this model extends the Rotilabo® flat-bottom series to ten-litre scale while preserving the same narrow-neck, heavy-rim design language used on the smaller sizes.\u003c\/p\u003e\n\u003c!-- lx-pdp-inline --\u003e\n\u003cp\u003eThis article is part of \u003ca href=\"\/en-be\/collections\/flat-bottom-flasks\"\u003eFlat-bottom flasks\u003c\/a\u003e, in \u003ca href=\"\/en-be\/collections\/beakers-and-flasks\"\u003eBeakers \u0026amp; flasks\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\u003eBrand: Rotilabo®\u003c\/li\u003e\n\u003cli\u003eCapacity: 10000 ml\u003c\/li\u003e\n\u003cli\u003eNeck: Narrow neck\u003c\/li\u003e\n\u003cli\u003eRim: Heavy duty rim\u003c\/li\u003e\n\u003cli\u003eHeight: 400 mm\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Carl Roth","offers":[{"title":"1 pc \/ 1 piece","offer_id":56184339267916,"sku":"NT79.1","price":135.9,"currency_code":"EUR","in_stock":true},{"title":"1 pc \/ 6+ pieces","offer_id":56184339300684,"sku":"NT79.1","price":129.11,"currency_code":"EUR","in_stock":true},{"title":"1 pc \/ 24+ pieces","offer_id":56184339333452,"sku":"NT79.1","price":122.31,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/4827\/7068\/files\/NT71-01-1000Wx1000H_70a77da2-81a7-47be-9d32-69cf1832560c.jpg?v=1766492525"},{"product_id":"flat-bottom-flask-w-ground-glass-joints-y653-y653","title":"Flat-bottom flask w. ground glass joints, 29\/32, DURAN®, 50 ml, 1 pc","description":"\u003cp\u003eFlat-bottom flask with ground glass joints NS 29\/32 is a 50 ml laboratory vessel made from DURAN® glass for general chemical and preparative work.
