Gravity Columns, 5 mL – FAQ

Q: What are they used for?
A: Perfect for small-scale protein and antibody purification, buffer exchange, and quick sample cleanup before downstream analysis.

Q: What samples can I load?
A: Typically cell lysates, fermentation supernatants, or antibody-containing culture media.

Q: What quality matters most?
A: Secure snap-on caps, stable frits for uniform flow, and clear columns ensure reliable and reproducible results.

Q: Any common challenges?
A: Flow control and recovery can be tricky at very small scales, but our well-designed frits and column geometry minimize dead volume and sample loss.

Q: Why choose these columns?
A: They’re compact, clean, consistent, and cost-effective—with multiple pack sizes (5 pcs / 25 pcs) for flexible lab use.

Q: Do these columns fit LabMate-style racks?
A: Yes—our 5 mL gravity columns fit most LabMate-style and universal chromatography racks designed for ~12 mm wells. If your rack uses special-size wells, please check the well diameter before purchase.

Q: Can I collect into 1.5 mL, 2 mL, or 15 mL tubes?
A: Yes. The outlet geometry allows stable positioning over microcentrifuge tubes (1.5/2 mL) as well as 15 mL conical tubes.

Q: Are these compatible with ion-exchange/affinity/gel-filtration resins?
A: Yes. The columns are supplied empty (no resin) and are compatible with common IEX, affinity (Ni-NTA, Protein A/G, GST, etc.), and size-exclusion media.
