means the specification sheet records no such opening for that band \u2014 small double-layer units and the 1\u20135 L single-layer range have no separate PTFE-sealed lid flange in the sheet. &#8220;Not recorded&#8221; means the extracted specification sheet does not state it; ask us rather than assuming. Port details for the 200 L and 150 L single-layer models are not recorded in the extracted sheet. Stainless steel reactors use millimetre flange sizes (e.g. \u03c640\/\u03c650 mm stirring flanges), a different naming system from the # joints above.<\/p>\n<h2>Port Questions<\/h2>\n<h3>What size is the stirring port on a small reactor?<\/h3>\n<p>It depends on the structure and band: 50# on 5 L double-layer units, 40# on 1\u20133 L double-layer and on all 1\u20135 L single-layer units, and 50# on 5\u201350 L triple-layer units. Read the band column that matches your model.<\/p>\n<h3>Can I swap a lid, funnel or condenser between two reactors?<\/h3>\n<p>The port sizes differ by structure and capacity band, and the specifications do not establish accessory interchangeability. Send both model numbers and the part details via the <a href=\"\/de\/contact-us\/\">contact page<\/a> for confirmation.<\/p>\n<p>Need a replacement part or a full configuration quote? <a href=\"\/de\/contact-us\/\">Contact UnionClay<\/a> with your model and the part you need.<\/p>",
