# Part Sourcing {% hint style="info" %} Check the upgrades guide [here](/evolver/upgrade-base-evolver-hardware.md). {% endhint %} ## Guidelines 1. Use the below Google Sheet to source parts for each of the eVOLVER subsystems (click on the tabs for different parts of the eVOLVER) 2. Parts may not be available due to backorder, discontinuation, or regional differences 3. If you are able to find an alternative vendor for a part, please post to the forum so it can be added to the spreadsheet 4. Should you not be able to order a part, post to the forum {% embed url="" %} ## eVOLVER Specific Parts Many eVOLVER parts must be 3D printed or are custom PCBs made to control eVOLVER hardware. For these, please see the [hardware GitHub](https://github.com/FYNCH-BIO/hardware) for CAD files and electronics parts lists for eVOLVER PCBs. ### Vial Caps Choose and 3D print vial caps for your application [here](/evolver/hardware/vial-caps.md). For most applications choose the "universal" cap. ### Other "Consumables" See Consumables tab in spreadsheet above. Recommended to buy several vial racks as well for ease of handling vials. ## Relevant Forum Posts {% hint style="warning" %} Note that the eVOLVER Consumables form post calls for 5/32" barbed connectors and 1/8" tubing. This is no longer recommended; refer to the "Fluidics tab" on the google sheet above and [media bottle and splitter guide.](/evolver/guides/making-media-bottles-and-splitters.md#overview) {% endhint %} [eVOLVER Consumables](https://www.evolver.bio/t/evolver-comsumables/189) [Vial Racks](https://www.evolver.bio/t/vial-racks-for-dishwashing-autoclaving/76) [Waste Containers](https://www.evolver.bio/t/waste-container-recommendations/72) --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
