Manufactured from PTFE, the sleeve sits between mating joint surfaces and helps reduce leakage and seizing during assembly of glass apparatus. It is intended for laboratory glassware set-ups in distillation, extraction and related work where NS 14\/23 joints are common. The single-unit pack supplies one sealing sleeve ready for immediate installation on compatible conical joints. At a pack weight of 0,007 kg, the component is lightweight and simple to keep with jointed glassware kits. PTFE construction offers chemical resistance suited to typical organic and aqueous laboratory media handled in jointed systems. This Rotilabo® accessory (ROTH SELECTION) belongs with seals and ridged sleeves for ground glass joints, supporting reliable connections in teaching, research and routine analytical labs.

The PTFE sleeve assists in forming a tight, demountable seal that limits vapour loss and helps prevent joints from sticking after thermal or solvent exposure. It is aimed at glass components used in distillation, extraction and general jointed assemblies where NS 29\/32 connections are specified. Each pack contains 1 unit, so sleeves can be matched one-to-one with individual joint pairs as apparatus is built or maintained. The article weighs 0,011 kg, making it easy to store with spare jointware and clamps. PTFE material is chosen for broad chemical compatibility in common laboratory environments.

The chrome-plated surface offers corrosion resistance suitable for typical laboratory environments while maintaining a clean, professional appearance. Weighing 0,230 kg and supplied as one piece, the joint integrates with standard grid-stand tubing and fasteners used to build custom apparatus supports, instrument platforms and teaching setups. From manufacturer Lenz, these ball joints allow technicians to create articulated nodes that accommodate non-orthogonal geometries without compromising mechanical stability. They are particularly useful when routing utility lines, positioning sensors or mounting glassware at precise orientations. The dense pattern of M12 threads supports multiple simultaneous connections, reducing the need for additional adapters.

Each ring helps bridge mismatched ground joints so apparatus can be configured without exchanging entire flasks or condensers. The complete set is supplied as one unit with a total weight of 0,100 kg, making it easy to keep on hand as a versatile accessory kit. Offered by manufacturer Bohlender, these reducer rings support flexible glassware setups in synthetic, analytical and preparative laboratories where joint compatibility is essential. Ideal for building or adapting ground-joint assemblies, the set simplifies equipment changes and reduces the need for multiple dedicated adapters.

They support reliable joint sealing in glassware used for distillation, extraction, and related glass-component setups where conical ground joints must fit cleanly and remain protected during assembly and use. PTFE construction is well suited to laboratory joint applications that require a chemically resistant sealing interface between mating ground surfaces. These seals help laboratories maintain consistent connections on conical ground joint glassware without altering the joint geometry itself. Each pack contains 50 pieces and has a net weight of 0,006 kg, making the format practical for stocking glass workshops, teaching laboratories, and routine synthesis or sample-preparation benches. The seals are offered by manufacturer Glindemann and belong with glass components, distillation and extraction accessories, and other ground-joint sealing products. Specifying the correct standard ground joint size 12 ensures compatibility with matching conical joints in existing apparatus. Compact pack quantity and defined joint size simplify replenishment and standardisation of PTFE seals across multi-user laboratory environments.\u003c\/p\u003e\n\u003c!-- lx-pdp-inline --\u003e\n\u003cp\u003eThis article is part of \u003ca href=\"\/en-be\/collections\/ground-joint-glassware\"\u003eGround-joint glassware (other)\u003c\/a\u003e, in \u003ca href=\"\/en-be\/collections\/distillation-and-extraction-glassware\"\u003eDistillation \u0026amp; extraction glassware\u003c\/a\u003e.\u003c\/p\u003e\n\n\u003ch3\u003eKey features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePack size: 50 pc(s)\u003c\/li\u003e\n\u003cli\u003eProduct type: Seals for conical ground joints\u003c\/li\u003e\n\u003cli\u003eMaterial: PTFE\u003c\/li\u003e\n\u003cli\u003eGround joint size: Standard ground joint 12\u003c\/li\u003e\n\u003cli\u003eWeight: 0,006 kg\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Glindemann","offers":[{"title":"50 pc(s) \/ 1 piece","offer_id":56186192167244,"sku":"T221.1","price":28.65,"currency_code":"EUR","in_stock":true},{"title":"50 pc(s) \/ 6+ pieces","offer_id":56186192200012,"sku":"T221.1","price":27.22,"currency_code":"EUR","in_stock":true},{"title":"50 pc(s) \/ 24+ pieces","offer_id":56186192232780,"sku":"T221.1","price":25.79,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/4827\/7068\/files\/T221-1000Wx1000H_6e5c5b9d-dc41-4248-bfc6-5f0ca8f17443.jpg?v=1766494455"}],"url":"https:\/\/www.luminixhealth.com\/en-be\/collections\/ground-joint-glassware.oembed?page=2","provider":"Luminix Health","version":"1.0","type":"link"}
