Description
Dropper lids made of high-density polyethylene (HDPE) with GL 25 thread provide secure, drop-dispensing closures for laboratory bottles that use the GL 25 neck standard. Fitted to compatible vessels, they enable controlled addition of reagents, indicators, buffers and other liquids in analytical, preparative and teaching work. The HDPE material is light yet durable for everyday bench handling and is appropriate for many aqueous laboratory media under normal conditions. This pack supplies 12 units, a practical quantity for stocking individual workstations or shared reagent stations without excess inventory. Pack weight is 0,072 kg, keeping storage demand low among other plastic consumables. Offered by manufacturer Vitlab within the containers, bottles and dropper-bottle category, the lids serve as interchangeable accessories for existing GL 25 bottle fleets rather than as complete filled systems. Consistent GL 25 threading supports reliable sealing and repeatable drop formation during routine protocols. Laboratories focused on wet chemistry, quality control and educational demonstrations can integrate these lids into standard dropper-bottle setups for clear, economical liquid handling.
This article is part of Pasteur pipettes, in Pipettes & pipette tips.

Questions about Dropper lids, made of HDPE, GL 25, 12 unit(s)
What is this article?
Dropper lids, made of HDPE, GL 25, 12 unit(s) is the article on this page. Luminix Health distributes Vitlab for laboratory use. It sits in Pasteur pipettes, inside Pipettes & pipette tips, in Lab consumables.
A Pasteur pipette is an uncalibrated glass or plastic transfer pipette. It moves a drop. It does not measure. Glass ones are pulled to a tip. Plastic ones are a single piece. Neither belongs in a result that needs a stated volume.
A pipette moves a measured volume. A volumetric pipette delivers one line. A graduated pipette delivers along a scale. A Pasteur pipette is an uncalibrated transfer. A piston pipette uses a tip, and the tip has to seal on that pipette. A filter tip adds a barrier so aerosol from the sample does not reach the piston. Serological pipettes are the long graduated tubes used with a controller. The volume and the fit are the specification. Piston pipettes are treated under ISO laboratory apparatus. In-vitro work also meets ISO in vitro diagnostic systems.
