Product Description
Need more bed volume without buying a whole new column? An extender adds length to an existing glass chromatography column so you can increase capacity or load larger samples while keeping the hardware you already own. It is a practical way to scale up a separation as your purification needs grow.
This listing is for Kimble catalog number 422440-1525: KONTES Chromatography Column Extender, 25 x 150 mm. Each extender is made from borosilicate glass 3.3 with a 25 mm inside diameter and joins the column using the two EP O-rings included in the package (size 124). It is offered in 150 mm and 500 mm lengths, letting you choose a modest increase or a substantial gain in packing volume. Order it from LIGHT LABS and keep your lab stocked with genuine DWK Life Sciences products.
Key Features
- Adds column length – Increases packed bed volume on an existing 25 mm ID column.
- Two lengths – Choose 150 mm or 500 mm to match the extra capacity needed.
- O-rings included – Two EP O-rings come with each extender for a sealed connection.
- Borosilicate 3.3 glass – Chemically resistant glass lets you watch the bed and bands directly.
