Whether you're packing a solution or injectable drug, serum bottles offer a sturdy and reliable means of protecting your valuables. Serum bottles are manufactured from high-quality Wheaton 400 borosilicate molded glass that provides excellent wall strength and chemical tolerance. They are ideal for both long and short-term storage, and are a great choice for packing chemicals and solutions. They also have a relatively low impact on the environment. They are also a good choice for storing sterile sera, culture media, and other sacrosanct samples.

The dropper tip is a great way to dispense your liquids. This device works by snapping over a special sealing ring on the bottle, which then distributes the fluid in a controlled fashion. It can dispense up to 40 uL of liquid when used with distilled water at room temperature. It also provides an effective moisture barrier, which will prevent your serum from going rancid.

The Tube Holder for 15 ml Tubes is a great way to hold your 15 ml tubes in an upright position. It fits inside a 750 ml flask, and holds up to nine of the aforementioned 15 ml tubes. The holder's patented design allows you to fit your bottle in an upright position while allowing for easy access to the contents. The holder is available in three different sizes, so you can fit just about any bottle.

Similarly, the frosted glass serum bottle is a great choice if you're looking for a reliable way to transport oils, serums, and essential oils. The bottle's glass dropper makes it easy to measure and dispense your liquids, and a rubber bulb is also included to ensure your product stays fresh. This frosted glass serum bottle is also refillable, so you can always restock your supplies. Its sharp-shouldered shape and timeless design makes it a great choice for the lab or home. Besides, you can use it to dispense your favorite essential oils, massage oils, and beard oils.

The Dropper Tip has a white polypropylene overcap that snaps over the bottle's special sealing ring. It's designed to dispense 40 uL of liquid per drop, and the cap also features a special rolled safety edge. The rolled edge makes it easy to tell if the cap has been properly tightened. A metal tab with the same design is also included for visual proof that the container is properly sealed.

The bottle cap is another great choice. This one features a large surface area, which allows you to label your bottle as well as protect your serum from damage. It also has a built-in screw cap to prevent it from leaking, making it an ideal choice for laboratory use.
