Upgrade Base eVOLVER Hardware

Vial Cap Upgrades

As of 25/01/15, FynchBio gives the cap that only accommodates needles. This cap does not have a tight seal on the vial and thus does not enable emergency efflux.

Benefits / Options

1. Better seal to vial - enables emergency efflux (see below) away from vial if too much is pumped in

2. More ports available

3. Reusable connectors - can use luer connectors to connect to eVOLVER tubing

See here for more information and construction protocols.

Emergency Efflux

Protect your eVOLVER hardware with a sealed vial and additional efflux line dedicated to preventing vial overflows.

Bubbling

Many organisms require additional gas exchange outside of what eVOLVER stirring can provide. Others require custom gas mixes for growth. In-vial bubblers provide this.

Stop Stir While Taking OD

This is a measure that is necessary if you are bubbling, but can improve OD in general by decreasing noise.

To do this, swap in a conf.yml with stir stopping.

You will need to calibrate with stir off. Swirl the vials when moving standards to make sure cells do not settle.
