Giá đỡ Gravity Flow Columns dùng trong tinh sạch protein

Stand to hold 4 x Gravity Flow Columns  (17 mm ⌀) used in Protein Purification.

The clamp grabs the column strong enough to be secure, but weak enough to adjust the height to elute into large 50 mL Falcon tubes or small 1.5 mL Eppis.

Multiple stands can be clipped together to parallelize more purifications.

Comes with a universal rack to hold 12x50mL Falcons, 12x15mL Falcons or 16x1.5 mL Eppendorf tubes, depending on rack orientation (can be rotated 90 degrees). The rack has the same 40 mm spacing than the stand.

Update 31.03.2023: Version 2 of the top part is available. Springs are more sturdy, and little hexagonal windows show tip of column more easily during purification.
