GeBAflex-tube Kit dialysis tube is an ideal choice for the preparation of biological samples. It can efficiently replace sample buffer or extract proteins, DNA or RNA from gels using dialysis and electroelution methods. The product has a double membrane design and large surface area, which can be used to concentrate biological samples. GeBAflex-tube Kit dialysis tubes are available in four types: Mini, Midi, Maxi and Mega, which are suitable for samples of different capacities.
The GeBAflex-tube Kit provides a convenient, universal system for preparing biological samples. It supports two operation modes—dialysis and electro‑elution—and is available in four capacity versions (Mini, Midi, Maxi, Mega). All steps are performed in a single centrifuge tube using standard laboratory pipettes, eliminating the need for syringes, special centrifuges, or dedicated electro‑elution devices.
The kit includes the appropriate tube size, a white rack that holds up to four tubes, and reagents such as MS‑Buffer, TCA, and 3 M acetate buffer. Detailed procedures cover membrane pre‑wetting, sample loading, buffer addition, placement in an electrophoresis chamber, voltage settings, and post‑elution cleanup, with performance data for protein, DNA and RNA recovery.

It supports two modes: dialysis and electro‑elution.
The Mega model is generally not suitable for DNA and RNA electro‑elution.
The membranes are super‑purified, EDTA‑treated regenerated cellulose and contain no sulfur or heavy metals.
Mega tubes have cut‑offs of 3.5 kDa (blue) and 6‑8 kDa (pink).
