Sortimentet finns i tre blanka ytfinisher i aluminium:<\/p>\n<ul>\n<li><a href=\"https:\/\/www.packaging.si\/sv\/produkt-kategori\/pipetter-alu\/pipetter-alu-gold-day\/\">ALU Gold Day<\/a> och ALU Gold Night f\u00f6r ett varmt, klassiskt utseende.<\/li>\n<li>ALU Silver Day och ALU Silver Night f\u00f6r ett neutralt, tekniskt utseende.<\/li>\n<li>ALU Rose Day och ALU Rose Night f\u00f6r en mjukare, varmare metallisk ton.<\/li>\n<\/ul>\n<p>Om du f\u00f6redrar en matt yta kan den separata ALU Matte-serien passa b\u00e4ttre. F\u00f6r en mer detaljerad genomg\u00e5ng av ytfinisher, se v\u00e5r artikel om droppers med aluminiumkrage.<\/p>\n<p>Oavsett vilken f\u00e4rg du v\u00e4ljer, be om ett prov och titta p\u00e5 det bredvid din faktiska flaska och etikett under normal belysning. Metalliska f\u00e4rger ser annorlunda ut p\u00e5 sk\u00e4rmen \u00e4n i handen.<\/p>\n<h2>Steg 5: Ograderad eller graderad pipett<\/h2>\n<p>Ograderade pipetter \u00e4r det enklare alternativet och r\u00e4cker ofta n\u00e4r kunden doserar med blicken eller dosen inte m\u00e4ts. Graderade pipetter har en skala som underl\u00e4ttar m\u00e4tt anv\u00e4ndning. Om du v\u00e4ljer graderad, definiera f\u00f6ljande i din specifikation:<\/p>\n<ul>\n<li>Vilken volym skalan ska representera, och om den st\u00e4mmer \u00f6verens med dina bruksanvisningar.<\/li>\n<li>Om skalan uppfyller dina krav p\u00e5 kvalitet och m\u00e4rkning.<\/li>\n<li>Om du beh\u00f6ver dokument f\u00f6r tryckta skalor.

NBR \u00e4r ett vanligt val f\u00f6r oljor, men inte alla formuleringar beter sig likadant. Starka l\u00f6sningsmedel, vissa eteriska oljeblandningar och produkter med h\u00f6g alkoholhalt kan p\u00e5verka gummit \u00f6ver tid. Innan du best\u00e4ller i volym:<\/p>\n<ol>\n<li>Fyll n\u00e5gra provflaskor med din riktiga produkt.<\/li>\n<li>F\u00f6rvara dem med droppern monterad, inklusive minst en som f\u00f6rvaras liggande eller upp och ner om det \u00e4r ett realistiskt f\u00f6rh\u00e5llande.<\/li>\n<li>Inspect the teat for swelling, stickiness, deformation or colour change at intervals that match your intended shelf life.<\/li>\n<\/ol>\n<p>This is a simple in-house check. It does not replace your own stability work, but it catches obvious incompatibility early.<\/p>\n<h2>Step 7: Plan for the filling and capping line<\/h2>\n<p>Aluminium collars have a shiny surface that can scuff. A few habits help protect the finish:<\/p>\n<ul>\n<li>Use capping heads or chucks that grip without hard metal contact, and check them for wear.<\/li>\n<li>Run a small trial batch to set the tightening force. Too little can cause leaks; too much can mark the collar or stress the bottle.<\/li>\n<li>Keep droppers in their bags until they are needed, and avoid loose piles that let collars rub against each other.<\/li>\n<li>Check the pipette tip against the bottle shoulder during the first assembled samples.<\/li>\n<\/ul>\n<p>For small runs, hand capping works if the operator is consistent. For larger runs, see our articles on semi-automatic and automatic capping machines.<\/p>\n<h2>Step 8: Write the specification<\/h2>\n<p>Once the above is decided, put it all in one line. A complete specification for an order could look like this:<\/p>\n<ul>\n<li>Bottle: 30 ml, DIN18 (GL18) neck<\/li>\n<li>Dropper: ALU Gold Day, white NBR teat, gold aluminium collar with PP inner part<\/li>\n<li>Pipette: 77 mm straight-tip glass, graduated<\/li>\n<li>Quantity: number of cartons<\/li>\n<li>Packing: any special requirement, such as individual bags<\/li>\n<\/ul>\n<p>Share this with your supplier and your own incoming inspection team. It becomes your reference when checking deliveries.<\/p>\n<h2>Vanliga misstag att undvika<\/h2>\n<ul>\n<li>Ordering by collar colour alone and checking the pipette length later.<\/li>\n<li>Assuming all bottles of the same volume have the same height.<\/li>\n<li>Approving a collar colour from a screen image.<\/li>\n<li>Skipping a compatibility trial with the real formula.<\/li>\n<li>Not defining plain or graduated in the purchase order.<\/li>\n<\/ul>\n<h2>Vanliga fr\u00e5gor<\/h2>\n<h3>Do all ALU droppers fit the same bottle neck?<\/h3>\n<p>Yes. All items in the ALU range use a DIN18 (GL18) thread. The pipette length changes with bottle volume, so check that as well.<\/p>\n<h3>What is the difference between Day and Night versions?<\/h3>\n<p>Day versions have a white NBR teat and Night versions have a black NBR teat. Collar colours and construction are otherwise the same.<\/p>\n<h3>Can I order a plain or a graduated pipette?<\/h3>\n<p>Both options are available for the ALU range. State your choice clearly when you order.<\/p>\n<h3>Can I get samples before placing a larger order?<\/h3>\n<p>Yes.
