Some Vials are specialized for Specified Medicine – A Handy Guide

If you need a special vial, there probably is one. Here are some other types of vials and how they work:

Bottle Filter – With a bottle filter, you can quickly and easily remove particulates from your samples in just a few steps. Filter bottles usually have a plunger with a filter on one end and a cap on the other. When you push the plunger into the vial, the liquid sample passes through the filter.

Filter bottles can help you improve your samples, save time, and reduce your setup requirements. These vials easily fit into regular trays and samplers where you will always need a vial decapper for your convenient opening of such bottles.

Conveyor vials: Conveyor vials are ideally sized and shaped for general sample collection and transportation. The carrier vials can stand alone with a flat or conical bottom to allow maximum sample retention. Otherwise, while borosilicate glass shipping vials may be the right choice for some samples, you can choose polypropylene to prevent samples from breaking on the way to or from your lab.

Open vial: Open vials have an inert polypropylene screw cap. There is a hole in the middle and under a layer of silicone or polytetrafluoroethylene called the septum. The septum is an airtight seal. With the lid open, an automated sampling needle can easily enter the septum and access the sample. Large openings in the cap reduce the risk of bending the auto-sampler needle.

Low evaporation filter vials: A low evaporation filter bottle has a special cap to reduce the evaporation rate. The cap is similar to a standard screw cap but allows for sample filtration.

Insert the vial

Vial accessories maximize sample collection and make it easy to dispose of vial contents. The attachments are a solution when the sample size is limited and an auto-sampler is required, as they increase the depth of the sample in the vial. The attacks are generally available in borosilicate or polypropylene glass and come in a variety of shapes. Type 1 borosilicate glass is typically used in chromatography, while polypropylene offers an economical option for use with pH-sensitive materials. Inserting a vial increases the depth of the sample in the vial.

Common styles featured include:

Tapered – Tapered inserts have a tapered bottom and can be fitted with damping springs.

Flat – The flat insert has a flat bottom and a cylindrical shape. They have the maximum potential and are arguably the cheapest option.

Spindle – Spindle inserts have precise points to reduce the amount of interference remaining. Inserts at the bottom of the clasp can be used when maximum sample recovery is required.

Vial caps prevent the vial from leaking

Caps for vials and septa

Closing the vial plays an important role in protecting the sample from spillage, contamination, and evaporation. Ideally, the lids should be airtight and inert. Caps can be supplied with a silicone or polytetrafluoroethylene (PTFE) septum which provides a good seal. The needles can pierce the septum as the elasticity of the material can close it again.

Septa are generally made of PTFE and silicone. Silicone septa have several advantages. For example, silicones can withstand very high and low temperatures and retain their flexibility. It is also chemically inert and does not affect the integrity of the sample. Finally, silicone is UV resistant and suitable for a variety of sterilization methods, including steam autoclaving. E-manuals are provided to you by Medical equipment suppliers for easy to tackle while buying such vials.

Which Vial is right and best for me?

If you are wondering which bottle is best for you, you know that it depends on several factors.

To help you choose the correct vial, consider the following:

Auto-sampler Compatibility: If you need vials to use with an auto-sampler, consider the type of auto-sampler you have and see if robotic weapons are used to collect vials or trays. If the auto-sampler uses compartments, you must select vials with the dimensions corresponding to the compartments.

Sample volume and composition: include sample size and type of substance to be tested. For example, if you have a limited sample size, you may need to include a packet with the vial. If you are working with a photosynthetic sample, choose an amber glass.

Vial material and it’s sealing: There are several factors to consider when installing valves under vial materials, such as storage methods, chemical inertness, and shelf life. Also, consider using or storing the vial with an auto-sampler and selecting a proper cap. Make sure the cap material is also inert.
