A 270 mm riser cap with a 20 ml measuring scale in 5 ml steps for dosing concentrates straight out of the Koch-Chemie 1-litre bottle. Not suitable for acidic or solvent-based products, and it doesn't fit canisters of 5 litres or more.\u003c\/em\u003e\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003cp id=\"speakable-definition\"\u003e\u003cstrong\u003eKoch-Chemie Dosing Cap\u003c\/strong\u003e is a dosing cap from Koch-Chemie (item no. 9998149) that works with a built-in 270 mm riser tube and a clear measuring scale from 5 to 20 millilitres in 5 ml steps. It replaces the standard closure on the 1-litre concentrate bottles and turns any bottle into a squeeze-driven dosing dispenser — no measuring cup, no splashing over the edge of the bench, no soaked labels.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-dosing-cap_hero.png?v=1777296505\" alt=\"Daniel from Detailing1 dosing Koch-Chemie Pol Star with the Dosing Cap dosing cap\" loading=\"lazy\" style=\"width:100%;height:auto;border-radius:4px;\"\u003e\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eScale in 5 ml steps up to 20 millilitres.\u003c\/strong\u003e One squeeze of the bottle and the concentrate climbs through the 270 mm riser tube into the clear measuring neck. You read off the amount and pour it straight into the spray bottle — for a Pol Star Po dilution at 1:10 that's exactly 10 millilitres, not \"about a good glug\" that you'll never hit again on the next bucket of wash.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRiser tube can be trimmed for 500 ml bottles.\u003c\/strong\u003e From the factory the tube sits at 270 millimetres, a perfect fit for the Koch-Chemie 1-litre standard bottle. For 500 ml spray bottles you trim it down to around 175 millimetres with scissors — the same cap then keeps working on the smaller bottles, so you don't buy a second one and you don't give up a second slot on the shelf.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLasts 100 uses and up.\u003c\/strong\u003e With alkaline products and car shampoos the plastic holds up for several years day-to-day — with a weekly Pol Star wash that's a good two years of service. Spread across the 3.49 EUR purchase price, your dosing cost lands under 4 cents per use. For a tool that saves between 5 and 15 millilitres of concentrate per wash, that's a purchase that pays itself off in two weeks.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003chr\u003e\n\n\u003cblockquote class=\"praxistipp\"\u003e\n  \u003cp\u003e\u003cstrong\u003eDetailing1's tip from the shop:\u003c\/strong\u003e Two mistakes cost you scale accuracy. First mistake: squeezing the bottle too hard — the concentrate shoots past the 20 ml line. Squeeze short and stop at the line instead. Second mistake: not flipping the little outlet flap on top open before you pour — then a vacuum pulls the liquid back, the bottle crackles, and the pour runs uneven. Manufacturer instruction: \"Open cap when dispensing.\" So always flip the flap open first, then pour.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eScrew on. Squeeze. Read off the scale.\u003c\/h3\u003e\n\u003cp\u003eThe \u003cstrong\u003eDosing Cap\u003c\/strong\u003e screws onto the 1-litre concentrate bottle, you give the bottle a quick squeeze from the side — the concentrate climbs through the 270 mm riser tube into the clear measuring neck and stops at the 5 ml line you want.\u003c\/p\u003e\n\n\u003cp\u003eIn detail it goes like this: unscrew the original closure, push the Dosing Cap with its riser tube into the bottle, screw it down clockwise. Hold the bottle upright and gently squeeze the long sides with both hands — you don't need any force, a controlled squeeze of about a centimetre is enough. As soon as the concentrate reaches the first 5 ml line, ease off the pressure. Need more? Just give it another quick squeeze.\u003c\/p\u003e\n\n\u003cp\u003eReal-world amounts from day-to-day work: for a Pol Star Po dilution at 1:10 for upholstery cleaning you dose 10 millilitres and add it to 90 millilitres of warm water. For Green Star \"Gs\" as a pre-cleaner you dilute 1:5, so 20 millilitres of concentrate in 80 millilitres of water — a full scale fill. For Active Foam \"Af\" in the foam lance container 1:20 is normal, so 5 millilitres per 100 millilitres of water. With the 5 ml resolution you're bang on the line for all three of these standard mixes.\u003c\/p\u003e\n\n\u003cp\u003eWhen you pour, open the little flap on top, hold the bottle at an angle and let the measured concentrate run into your \u003ca href=\"\/en\/products\/koch-chemie-hdpe-zylinderflasche-28-400-spruehflasche-1000ml\"\u003eempty HDPE spray bottle\u003c\/a\u003e or mixing container. Top up with water, fit the spray head, done. If you mix several dilutions per session, you save yourself the measuring cup and the leftover in the cup that otherwise gets spilled or tipped away.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-dosing-cap_anwendung.png?v=1777296518\" alt=\"Concentrate climbing into the 5 ml scale of the Koch-Chemie Dosing Cap dosing cap\" loading=\"lazy\" style=\"width:100%;height:auto;border-radius:4px;\"\u003e\u003c\/p\u003e\n\n\u003ch3\u003eAlkaline and shampoo: yes. Acids and solvents: no.\u003c\/h3\u003e\n\u003cp\u003eThe Dosing Cap is expressly cleared by the manufacturer for alkaline cleaning concentrates and car shampoos. Acids and solvents attack the plastic of the scale over time — that's the most important limit on where you use it.\u003c\/p\u003e\n\n\u003cp\u003eIn concrete terms: across the Koch-Chemie range the cap fits the alkaline all-purpose cleaners Green Star \"Gs\", multi-purpose cleaner \"Mzr\" and Allround Surface Cleaner \"Asc\", the pre-cleaners Pre-Foam efficient \"Pfe\" and Pre-Wash B \"Pb\", Active Foam \"Af\" for the foam lance, the car shampoo \"As\", the NanoMagicShampoo \"Nms\" plus the upholstery care Pol Star \"Po\" and the plastic-care concentrates. That covers around eighty percent of the typical Koch-Chemie detailing workflow.\u003c\/p\u003e\n\n\u003cp\u003eWhere the cap is not suitable is Triple Acid Star \"Ta\" and other acidic wheel cleaners, Reactive Rust Remover \"Rrr\", Magic Wheel Cleaner \"Mwc\", and solvent-based products like stain remover \"Fw\" or tar remover. Acids soften the scale markings, solvents can make the plastic brittle — either way you lose the measuring accuracy after a few uses. For those products stick with the original closure or work with a measuring cup.\u003c\/p\u003e\n\n\u003cp\u003eThe second clear limit is the bottle. The riser tube is matched to 270 millimetres, so it fits the standard 1-litre Koch-Chemie bottle and, once trimmed, the 500 ml spray bottles. It doesn't fit the 5-litre, 10-litre or 25-litre canisters — those have a different closure diameter and too much height for the riser tube.\u003c\/p\u003e\n\n\u003cp\u003eIf you want to dose straight out of the 5-litre canister, you need a different solution like the \u003ca href=\"\/en\/products\/carpro-measure-cap-dosierkappe\"\u003eCarPro Measure Cap\u003c\/a\u003e, which screws onto 28\/400-thread spray bottles and works on a decant principle rather than dosing straight from the storage container.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-dosing-cap_ergebnis.png?v=1777308590\" alt=\"Concentrate mixing system with Koch-Chemie Dosing Cap HDPE bottle and spray head\" loading=\"lazy\" style=\"width:100%;height:auto;border-radius:4px;\"\u003e\u003c\/p\u003e\n\n\u003ch3\u003eIf you dose Koch-Chemie concentrates, you want it.\u003c\/h3\u003e\n\u003cp\u003eThe Dosing Cap pays for itself from the second concentrate on the shelf. If you keep Pol Star, Green Star and Pre-Foam in 1-litre bottles, you mix two to three dilutions per detailing session — eyeballing it burns more concentrate over the year than the cap costs.\u003c\/p\u003e\n\n\u003cp\u003eIt breaks down into three profiles. For the hobby detailer with two or three concentrate bottles the cap is a one-off 3.49 EUR outlay that makes your own mixes repeatable — a 1:10 dilution is genuinely 1:10 next time, not \"a touch too weak\" or \"a bit too foamy\".\u003c\/p\u003e\n\n\u003cp\u003eFor the semi-pro and the workshop detailer who mixes several dilutions a day, the cap saves concentrate — a rough 15 ml guess instead of a measured 10 ml dose adds up to two or three litres of Pol Star too much over the season. The cap makes less sense if you only use a single ready-mixed spray product and don't dilute any concentrates at all — then you simply don't need it.\u003c\/p\u003e\n\n\u003cp\u003eOn the Detailing1 shelf, three building blocks make one complete concentrate mixing system: the \u003cstrong\u003eKoch-Chemie Dosing Cap\u003c\/strong\u003e on the concentrate bottle, the \u003ca href=\"\/en\/products\/koch-chemie-hdpe-zylinderflasche-28-400-spruehflasche-1000ml\"\u003eHDPE cylinder bottle 1 litre\u003c\/a\u003e as the mixing container and the \u003ca href=\"\/en\/products\/koch-chemie-spruehkopf-spruehflasche-set\"\u003espray head \"Star\" with spray bottle\u003c\/a\u003e as the finished set. You dose from the concentrate into the HDPE bottle, top up with water, fit the spray head — three moves, a repeatable mix, no measuring cup in the sink. All in, the system costs you under twelve euros and saves you buying every separate spray-bottle component on its own.\u003c\/p\u003e\n\n\u003cp\u003eIf you mix several concentrates in rotation, label the HDPE bottle with a permanent marker along the bottom edge: dilution and date. Sounds trivial, but day-to-day it's exactly what sits between a repeatable workflow and a \"not sure what's in here any more\" mix.\u003c\/p\u003e\n\n\u003cp\u003eThe Dosing Cap itself stays on the concentrate bottle, the spray head stays on the HDPE bottle — you only swap the concentrate, and you always measure on the same 5 ml scale. That's the one Detailing1 tip that has nothing to do with the product and everything to do with the routine around it: standardisation beats improvisation, every time.\u003c\/p\u003e\n\n\u003cp\u003eThe handful of buyer reviews for the cap confirm the point that matters most in the product's logic: the fit on the Koch-Chemie 1-litre bottles is spot on. Verified buyers report matter-of-factly that the cap \"fits\", which on a riser-tube system with a fixed length spec is all that counts.\u003c\/p\u003e\n\n\u003cp\u003eThe real Detailing1 value isn't in the cap, it's in the discipline. Once you've dosed with a 5 ml scale, you never go back to eyeballing — and only then do you notice how much concentrate used to vanish into the bucket water, because a 1:5 dilution was really a 1:3 and the whole litre of Pol Star was gone after 8 washes instead of 20.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-dosing-cap_lineup.png?v=1777296541\" alt=\"Koch-Chemie Dosing Cap dosing cap macro with 5-20 ml scale and riser tube\" loading=\"lazy\" style=\"width:100%;height:auto;border-radius:4px;\"\u003e\u003c\/p\u003e\n","brand":"Koch-Chemie","offers":[{"title":"Default Title","offer_id":48818350031183,"sku":"D1-KCX-9998149","price":4.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/9998149__1714225866.png?v=1714252294","url":"https:\/\/detailing1.lu\/en\/products\/koch-chemie-dosing-cap-dosierkappe-flaschen-270mm","provider":"Detailing1","version":"1.0","type":"link"}
