What are the Elveflow Microfluidic Reservoirs?

Elveflow microfluidic reservoirs are autoclavable adapter caps that convert standard lab consumables — Eppendorf® tubes, Falcon® tubes, and GL45 glass bottles — into pressurisable microfluidic reservoirs. Combined with an OB1 pressure controller, the cap pressurises the container and pushes the liquid through standard 1/16" OD microfluidic tubing into the chip or downstream instrument.

Six size ranges are available, from XXS (800 µL) all the way up to HP (350 mL), with most sizes available in 2- or 4-port versions to suit single- or multi-line setups. All wetted parts are hard-anodised aluminium with Viton O-rings for the tube adapters, or POM/PTFE caps for the larger glass bottles — making the reservoirs both durable and chemically robust.

Key Features

• Wide size range: XXS (800 µL), XS (1.5–2 mL), S (15 mL), M (50 mL), L (100 mL), HP (150 mL & 350 mL).
• Standard consumables: Direct fit for Eppendorf® and Falcon® tubes plus GL45 bottles.
• 2-port or 4-port versions: Single or multi-line outputs (depending on size).
• Autoclavable: Infinitely reusable, fully sterilisable.
• Robust construction: Hard-anodised aluminium adapters with Viton O-rings; POM/PTFE bottle caps.
• Standard fittings: Compatible with ¼-28 fittings for 1/16" OD microfluidic tubing.
• Pressure-rated: Validated across the full OB1 pressure channel range (200 mbar to 8000 mbar, plus vacuum ranges).

Applications

These reservoirs are core consumables for virtually any pressure-driven microfluidic experiment. Common applications include:

• Cell culture perfusion with sterile, autoclavable medium reservoirs.
• Reagent storage and delivery for sequential injection experiments.
• Long-term experiments needing high-volume reagent reserves (up to 350 mL).
• Organ-on-chip platforms with multi-line 4-port reservoir caps.
• Stem cell, drug screening, and toxicology assays with sterile sample handling.
• Closed-loop recirculation setups paired with the MUX Recirculation valve.
