BioTek MultiFlo FX

Automated multimode reagent dispenser for 6- to 1536-well microplates

Information

MultiFlo™ FX is an automated reagent dispenser for 6- to 1536-well microplates. Its unique Parallel Dispense™ technology allows up to four independent reagents to be dispensed in parallel without potential carryover. What makes MultiFlo FX “multi-mode” is its configurability: you can add a wash module or the RAD™ module, for random access individual well dispensing and bulk dispensing larger wells. Everything you need for fast, intuitive programming and operation is available through the color touchscreen. MultiFlo FX configured with either the wash module or RAD technology replaces up to five liquid handlers in a single compact platform.

Multi-mode dispensing can replace up to 4 dispensers and a washer
Parallel Dispense™ technology: peristaltic and/or syringe pumps
RAD™ technology for dispensing to individual wells
Cost savings through low prime volume and single tube access
Cell friendly angled dispense and/or wash tubes won’t disrupt cell layers

LHC LHC Software allows computer-based programming of multi-step processes and it is used for integrating BioTek’s multi-mode washer dispensers, washers and dispensers into robotic systems. You can operate the system under computer control via LHC, or create protocols in LHC and download to the instrument for recall and execution. LHC Secure software LHC Secure software offers features to facilitate compliance to FDA directive 21 CFR Part 11 with computer control of BioTek’s Multi-Mode Washer Dispensers, Washers and Dispensers. LHC SiLA software LHC SiLA softwaredriver enables BioTek washer and dispenser integration into SiLA compliant automated systems. Includes LHC software for computer control and third party integration of BioTek’s Multi-Mode Washer Dispensers, Washers and Dispensers.

Spheroidal 3D cell culture is increasingly common for many research areas as it better mimics the in vivo environment. It can be challenging to perform media exchanges and washes without accidental cell structure loss. BioTek’s patent-pending AMX™ module for the MultiFlo™ FX enables gentle automated media exchange to protect and encourage proliferation of spheroids, tumoroids and other 3D cell structures, 2D and suspension cells in microplate-based assays The AMX module uses both peristaltic pumps, one to dispense and one to aspirate media from the plate wells. The software operates the pumps slowly and gently so cells and cell structures aren’t disturbed during the media exchange, and the x-y-z positions for the aspirate and dispense tubes are adjustable to avoid contact, etc with cell structures in the wells. The two peristaltic pumps and software control the media flow through the cassette tubing and manifolds into the microplate. The arrows indicate the flow pattern. Close-up views show the critical positioning of the dispense tubes (left) and aspirate tubes (right) during media exchanges.AMX Benefits:

Automates media exchange for spheroids, tumoroids and other 3D cell structures, 2D and other cell structures
Helps protect cells and encourage cell structure growth
AMX module can be added to MultiFlo FX and easily exchanged with other modules for workflow versatility

Multi-mode dispensing can replace up to four dispensers and a washer Providing unsurpassed liquid handling flexibility, MultiFlo FX’s modular base can accommodate 1 or 2 peristaltic pumps, a 2-syringe pump module and a wash module or a single channel dispense. MultiFlo FX takes the place of multiple instruments, but is compact and very simple to use. Parallel Dispense™ technology: peristaltic and/or syringe pumps Peristaltic pumps and syringe pumps each offer benefits; peri-pumps help save precious reagent, while syringe pumps are fast and precise. MultiFlo FX can be configured with 2 peri and 2 syringe pumps, allowing up to four reagents to be dispensed in parallel, without carryover. RAD™ technology for dispensing to individual wells When the liquid handling workflow calls for individual well dispensing along with rapid bulk dispensing, MultiFlo FX can handle it. The unique RAD module provides single channel dispensing to discrete wells of a 48-, 96- or 384-well plate. For rapid single channel dispensing to 6- to 24-well plate, the 8-to-1 RAD cassette is perfect for the task. Cost savings through low prime volume and single tube access With programmable prime volumes, backflush capability and the unique single tube access with RAD, you’ll save on costly reagents for all your dispensing processes. Cell friendly angled dispense and/or wash tubes won’t disrupt cell layers For sensitive cell-based assays, the dispense tips on the MultiFlo FX dispense manifolds and wash manifolds are angled, allowing gentle reagent dispense down the well sides. This helps keep cell layers intact, even through multiple-step operations. Walkaway automation with BioStack 4 or BioSpa 8 for lidded or unlidded plates Integration BioStack to MultiFlo FX allows automated processing of multiple plates at a time, without manual intervention. MultiFlo FX integrated to BioSpa 8 adds automated media exchange and reagent addition to automated live cell workflows.
