If you need a special flask, there will likely be one. Here are some other types of flasks and how they work:
Bottle Filter –
With a bottle filter, you can quickly and easily remove fine dust from your samples in just a few steps. The filter bottle press generally has a filter on one side and a cap on the other. When you depress the plunger in the vial, the fluid sample passes through the filter.
Filter bottles can help you improve your samples, save time and reduce installation needs. These bottles easily fit into common sampler trays as a bottle cap is always required to easily open these bottles.
Transport Vessels:
Transport vessels are of an ideal size and shape for sampling and general transport. The carrier flasks can be freestanding with a flat or conical bottom to allow maximum sample retention. While borosilicate glass transfer tubes may be the right choice for some samples, you can choose polypropylene to prevent samples from breaking on the way to or from the lab.
Opened vial:
Opened vials contain an inert polypropylene screw cap. There is a hole in the middle and under a layer of silicone or polytetrafluoroethylene called a septum. The septum is an airtight seal. With the cap open, the motorized sampling needle can easily enter the septum and access the sample. Large openings in the cap reduce the risk of bending the needle of the automatic sampler. Opened Vials are easy to handle with vial decapper pliers.
Low Evaporation Filter Bottles:
The low evaporation filter bottle has a special cap to reduce evaporation. The cap is similar to a standard screw cap but allows sample filtration.
Vial attachments
Vial attachments increase sample collection and facilitate material removal from vials. Accessories are a solution when sample volume is limited and an automatic sampler is required, as they increase the depth of the sample in the vial. Fasteners are generally made of borosilicate glass or polypropylene and come in a variety of shapes. Inserting a vial increases the depth of the sample in the vial.
The common patterns are:
TAPERED – The conical interior has a tapered bottom and springs can be attached for damping.
Flat: They have the most potential and may be the cheapest option.
Envelope insert: The envelope insert has precision tips to reduce residual interference. Entries at the bottom of the closure may be used where maximum sample size is required.
Bottle caps and septum
The closure of the vial plays an important role in protecting the sample from spillage, contamination and evaporation. A silicone or polytetrafluoroethylene (PTFE) barrier can be provided for the caps to ensure a tight seal. Needles can penetrate the septum because the elasticity of the material can block it.
The fender is usually made of PTFE and silicone. The silicone barrier has many advantages. Silicon, for example, can withstand extremely high and low temperatures and retain its flexibility. Finally, silicone is UV-resistant and suitable for a variety of sterilization methods, including steam sterilization. Medical device vendors provide electronic brochures for your convenience when purchasing these vials.
Which bottle is the best overall?
If you are wondering which bottle is right for you, you know that it depends on several factors.
To help you choose the right vial, consider the following:
Auto sampler Compatibility: If you need vials to use with an autosampler, consider the type of autosampler you have and see if robotic weapons are used to collect vials or bowls. If the automatic sampler uses chambers, choose flasks with chamber sizes.
Sample size and composition refers to the sample size and the type of study material. For example, if you have a limited sample volume, you may need a vial package. If you are working with an optical sample, choose amber-coloured glass.
Vial material and seal: There are many factors to consider when installing valves under the vial material, for example: Also consider the use or storage of the vial with an automatic sampler and choose the appropriate seal. Make sure the cover material is inert.
