Oils, alcohol-based blends, essential oils and water-based serums behave differently against plastics and elastomers. Before approving a combination, ask:<\/p>\n<ul>\n<li>Is the teat material suitable for the liquid you fill? NBR, silicone and TPE respond differently to different liquids, so test with your actual formula.<\/li>\n<li>Does the product contain strong solvents or fragrance components that may soften or swell plastic parts?<\/li>\n<li>Is the liquid thin enough to leak around a plug, or thick enough to flow poorly through a roll-on ball seat?<\/li>\n<\/ul>\n<p>We do not state chemical resistance data unless it is in the product specification, so the practical answer is always to run a compatibility test with your own product and your chosen parts.<\/p>\n<h2>Step 5: Roll-on sets, a worked example<\/h2>\n<p>Roll-on sets show why a combined check matters. A set such as the <a href=\"https:\/\/www.packaging.si\/fi\/kauppa\/osat-komponentit\/tulpat-guardseal\/roll-on-tulppa-teraskuulalla-din18-lapinakyva-tulppa-ja-musta-pp-korkki-ilman-sinettirengasta\/\">steel ball roll-on plug for DIN18 bottles with a transparent plug and black PP screw cap<\/a> brings together a stainless steel ball, a transparent plug and a screw cap. The plug holds the ball and seats in the neck, and the cap closes over it.<\/p>\n<p>Before ordering a carton, check:<\/p>\n<ol>\n<li>That the bottle is a DIN18 finish.<\/li>\n<li>That the fill is suitable for a ball applicator. Very thin liquids may run more freely than you want.<\/li>\n<li>That the cap color suits the bottle and label design. The same set is offered with different cap colors, so match it to your artwork early.<\/li>\n<li>That the cap closes fully and feels consistent across several units, not only one sample.<\/li>\n<\/ol>\n<p>Meid\u00e4n <a href=\"https:\/\/www.packaging.si\/fi\/tuote-osasto\/osat-komponentit\/tulpat-guardseal\/\">GuardSeal plug range<\/a> lists the other plug types if a roll-on is not the right format for your product.<\/p>\n<h2>Step 6: Check pipette and bottle height together<\/h2>\n<p>Pipettes are the part most often mismatched to the bottle. If the tip rests on the bottom, it can limit draw-up and make the last portion of product hard to reach. If it is too short, the tube may not reach the liquid as the level drops. Always measure the sealed assembly with the bottle upright rather than comparing two numbers on paper. Our <a href=\"https:\/\/www.packaging.si\/fi\/tuote-osasto\/osat-komponentit\/lasipipetit-clearflow\/\">lasipipettimme<\/a> are available in more than one format, so pick based on the bottle you actually use.<\/p>\n<h2>Step 7: Run a small pilot before the full order<\/h2>\n<p>A short pilot catches most of what a spec sheet cannot. A reasonable routine:<\/p>\n<ol>\n<li>Assemble five to ten complete units with the exact parts you plan to order.<\/li>\n<li>Fill them with the real product, not a stand-in.<\/li>\n<li>Cap with the torque or pressure your line will use.<\/li>\n<li>Store some upright and some on their sides for a few days, then inspect for seepage at the neck.<\/li>\n<li>Dispense from each unit and check that the function is consistent.<\/li>\n<li>Ship a few units in your normal carton and check them again on arrival.<\/li>\n<\/ol>\n<p>Record the results with part descriptions, so a reorder months later uses the same combination.<\/p>\n<h2>Keep a simple parts record<\/h2>\n<p>Once a combination works, document it. A one-page record is enough:<\/p>\n<ul>\n<li>Bottle description and neck finish<\/li>\n<li>Every component with its description and color<\/li>\n<li>Fill product and batch used in the test<\/li>\n<li>Date of the test and the person who approved it<\/li>\n<\/ul>\n<p>When any part changes, repeat the pilot. It takes a short time compared with the cost of a recalled batch.<\/p>\n<h2>UKK<\/h2>\n<h3>Are all DIN18 parts interchangeable?<\/h3>\n<p>They are designed around the same neck finish, but you should still confirm fit with a sample. Differences in plug design, collar shape and cap style can affect how parts work together.<\/p>\n<h3>Can I change only the cap color on an existing assembly?<\/h3>\n<p>Usually yes if the cap model stays the same, but check that the new batch seats and seals the same way. If the cap style changes, treat it as a new combination and test it.<\/p>\n<h3>Should I test with water or my actual product?<\/h3>\n<p>Use your actual product. Viscosity, solvents and fragrance components can change how a plug seals, how a ball rolls and how an elastomer behaves.<\/p>\n<h3>Voinko saada n\u00e4ytteit\u00e4 ennen laatikkotilausta?<\/h3>\n<p>Yes.
