SUBmerged™ ATF P-SUB size 2 liter VV keep HFF free from fouling
Benefits of this particular P-SUBmerged are:
- avoid HFF fouling – freedom to select broth velocities for gentle harvest and sequential pulses flushing out debris from inside the HFF
- eliminate dead volume – skip all the hoses, traditional plastic connectors and SUBmerge the HFF
- avoid cell death - inverted Thalia pump arranged on top of the HFF = hereby the diaphragm pump cannot accumulate cells
- reduce shear force – protect cells by eliminating hoses, fittings - SUBmerge the HFF inside the P-SUB and the inverted Thalia on top of HFF
- increased Kla values - aeration via membrane for gas diffusion - 30% better via large surface area tubular pico-sparger
Industry leading architecture P-SUB pre-assembled and ready to install:
- 0.5 – 1.5 liter Working Volume (WV) from 2 liter Vessel Volume (VV) OD 110 mm
As this P-SUB feature an extra PG13 port these 2 SepraPor® / Thalia PG13 kit options are possible:
- SepraPor HFF OD 9.5 x 300 mm, 110 cm2, LASER guided Thalia TM60A
- SepraPor HFF OD 12 x 300 mm, 170 cm2, LASER guided Thalia TM60A
- SUBmerged SepraPor unified with inverted Thalia direct connection (no Luer-Lok or TRI-clamps) for reduced shear stress
- Inverted ground-breaking LASER guided Thalia TM60A diaphragm Single-Use-Pump (A-SUP)
- Single-Use-Sensors (SUS) VisiWell for DO, OneFerm pH, (optional InCyte bio-mass on SUB wall with HSF), temp well, level as needed
CellRetention-2 ATF extended KLa
CellRetention-2 ATF tight headplate
CellRetention-2 ATF on HSF in MST
All three photos show the 2 liter P-SUB with OD 4 mm thin wall silicone hose Membrane-Diffusion-Cage for better KLa values compared to micro sparger. Right photo show the P-SUB mounted in the Heating-Support-Foot (HSF) bolted on the Magnetic-Stirrer-Table (MST) separating the black servo motor from the P-SUB headplate. The HSF is a perfect thermal control with sufficient contact to the P-SUB surface for accurate temperature regulation. Red LASER sensor mounts in a Re-Usable-Bracket above the dome of the inverted Thalia TM60A A-SUP.
General features of CellRetention™ 2 liter P-SUB for Head-Plate-Drive (HPD):
- Head plate with 4 x PG13.5 circumference ports and 6 ports for In&Out with small diameter hoses, exhaust, temp well
- Center PG13.5 occupied by HPD bearing assembly
- Thermal control by PerfuseCell Heating-Support-Foot and agitation by slim-line servo motor
- Thermal control by Eppendorf SciVario ThermoWell and the Maxon RE30 motor
General features of CellRetention™ 2 liter P-SUB with Magnetic-Bottom-Drive (MBD):
- Headplate with 5 x PG13.5 circumference ports and 6 ports for In&Out with small diameter hoses, exhaust, temp well
- With MBD the P-SUB mounts in PerfuseCell Heating-Support-Foot (for electrical thermal control) which is mounted onto the PerfuseCell Magnetic-Stirrer-Table (MST) for agitation by any servo motor
CellRetention-2 ATF HPD PG13 kit
Thalia TM60A SUP unified with the SepraPor 110 cm2 HFF and mounted in PG13 headplate port. P-SUB inserted in ID110 mm ThermoWell for thermal control with Maxon RE30 for Head-Plate-Drive controlled by SciVario. The DO WisiWell and Hamilton pH SUS pre-installed in the headplate. Direct-Fit connects HFF to Thalia for better flow performance and lower shear stress. See this link - stress free connections
