Versatile microfluidic reservoir caps made of corrosion-resistant and autoclavable Delrin that can be fitted onto standard GL45 glass bottles. A choice of two different microfluidic caps with either two or four 1/4-28 threaded ports, allowing customizable interfaces with microfluidic fittings.

General

The microfluidic caps are compatible with any GL45 threaded bottles. They come with 1/4-28 threaded ports for 1/16" and 1/8" OD tubing and are available in both 2-port and 4-port versions. The 2-port version is ideal for applications requiring only a single fluid output, whereas the 4-port version can be configured to allow for three parallel fluid outputs using a single pressure source.

The caps are made of autoclavable Delrin, a polymer material also known as acetal or Polyoxymethylene (POM), and possess high strength and corrosion resistance to a wide range of compounds.

The standard 100 mL glass bottle included has a simple yet robust design, allowing infinite reusability and giving the option of using large sample volumes or performing long microfluidic experiments.

Features & Benefits

Setup

The reservoirs are intended to be used in conjunction with a pressure source, whereby the reservoir is pressurized to facilitate the controlled pumping of liquid from the reservoir into a microfluidic system. An example of a complete setup utilizing the microfluidic cap and reservoir kit is demonstrated in the schematic below.

Safety Warning

Working with systems under pressure above atmospheric pressure presents a safety risk, especially when working with hazardous liquids and gases.

Darwin microfluidics cannot guarantee the strength of the provided reservoirs beyond atmospheric due to the nature of their material, transportation, and end-user handling methods. It is thus the responsibility of the end-user to take necessary precautions to ensure their safety, including careful handling and operation and wearing personal protective equipment.

Working with pressurized reservoirs requires following some recommendations to ensure your security.

Recommended pressure range: from -900 mbar to 2 bar. The reservoir passed the resistance tests for pressures higher than 2 bar, nevertheless, Elveflow does not recommend using it under these conditions because mechanical damage could occur.

Pressure resistance tests have been performed on the pressurized tanks. Protocols and results of the tests are available upon request.

• Do not use a tube or a bottle that looks damaged or has encountered a shock.
• Use only the same tube references if you need a spare one. We cannot guarantee that other references of tubes or bottles used by the end-user will withstand the same pressure ranges.
• Make sure that the tube/bottle used with Elveflow pressurized tube cap is adapted to the experimental conditions (chemical compatibility of the material, resistance to temperature, …) to fulfill security requirements.
• Use security equipment adapted to specific experimental conditions. You may be using pressurized reservoirs containing dangerous liquids and presenting explosion risks (protection glasses, security net, or shield). Also, depending on the nature of the liquid, it is the user's responsibility to use indicated security equipment (PPE, chemical hood, …).
