Liquid handlers are gaining in popularity in all types of laboratories because they offer significant man-hour savings through automation. However, the range of automated liquid handlers available may be overwhelming, making it difficult to decide what would be the best choice for the unique circumstances of your laboratory.

Use the following decision tree to help narrow your equipment selection.
What type of automated liquid handler do you require?
The simplest types of liquid handlers are automated pipettes or dispensers. These instruments are designed to dispense precise and measured quantities of a liquid into a receptor vessel, usually a microplate.
What type of dispensing do you require?
Single-channel dispensers deliver a single measured volume of a solution in a sequential manner.
Multi-channel dispensers are one of the most commonly used types of automated liquid handling devices, capable of simultaneously delivering a number of measured aliquots of a solution directly into a receiver vessel, usually a microplate.
Non-contact liquid handling reduces risk of contamination and is ideal for many sub-micro liquid handling tasks.
A wide range of automated liquid handlers offers greater functionality than the simple liquid dispensing offered by the more basic models. Some of the most common functions include nucleic acid preparation, ELISA, assay automation, high-throughput screening and protein crystallography, although many other applications exist.
What type of integrated workstation do you require?
Multi-function workstations can be used for both clinical and research applications, including automated barcode tracking of samples, reagents, labware, racks and carriers in a variety of automated processes.
Nucleic Acid Preparation / PCR
Automated liquid handlers designed for nucleic acid preparation tend to enable automated RNA, mRNA, gDNA, and plasmid preparation, for example, as well as a wide range of downstream applications.
Automation of ELISA processes is an area of increasing importance to laboratory managers worldwide. A number of automated liquid handlers offer automation of microplatebased chromogenic ELISAs, which can be adapted to meet the changing workflow and throughput requirements of today’s diagnostic laboratory.
Next-generation sequencing liquid handlers are emerging as valuable tools in providing large amounts of genetic information in a single run, increasing throughput and reducing sequencing costs. These liquid handlers are finding application in primary research, health screening, personalized medicine, and single nucleotide polymorphism characterization.
Solid Phase Extraction/Liquid Liquid Extraction
Automated liquid handlers can be used for liquid liquid extraction (partition chromatography) from sample addition to organic phase removal, with high precision, throughput and accuracy. Solid phase extraction (SPE) allows rapid sample preparation and purification for chromatographic or other analyses. SPE can be automated using dedicated automated liquid handlers.
BrandTech Scientific BRAND Liquid Handling Station
The BRAND Liquid Handling Station pipetting robot handles routine tasks at high speed and with the highest precision. The LHS closes the gap between electronic pipettes and highly complex, expensive pipetting robots. It is a quiet and compact instrument with a unique front door allowing it be set up in tight quarters. The instrument has 7 working positions and 5 available liquid ends with single channel volumes up to 1000uL and multichannel volumes up to 300uL. The system has the flexibility to move liquids between reservoirs, tubes, and plates. Adapters and racks bring the consumables to an even height, reducing unnecessary vertical movements to save time during pipetting.

BrandTech Scientific Dispensette® S Bottletop Dispenser
NEW! The Dispensette® S bottletop dispensers build on the 50 year history of BRAND dispensing expertise. Continual upgrades makes this the safest and most convenient ever, while retaining the features making the Dispensette® the world's favorite bottletop dispenser. The "floating piston" design of the Dispensette® S forms a zero-wear sealing system with outstanding sliding properties. Optimized flow channels make dispensing and priming even easier - particularly in instruments with large volumes.
BrandTech Scientific BVC Fluid Aspiration Systems for Cell Culture
The NEW BVC family of fluid aspiration systems deliver compact and quiet solutions for cell culture work. They provide the flexibility to accommodate your decontamination protocol whether you autoclave or disinfect in the bottle.
Basic. The BVC Basic is the unpowered version, suitable for use with a VACUU•LAN® vacuum network, central vacuum system or shared pump. A mechanical regulator provides a suitable vacuum level in the bottle for aspiration, and disconnects it from the supply when that level is reached – no power required! This reduces demand on the vacuum supply, increasing efficiency while reducing noise and impact on other applications. Ready for use - supplied with a stable and easy-to-clean powder coated metal stand, 0.2Μm biofilter, and VHCPRO hand controller. Available in heavy duty polypropylene or disinfectant-resistant "G" glass versions.
Control. The BVC Control features a powerful, whisper-quiet VACUUBRAND® chemistry-design vacuum pump, eliminating the need for central vacuum supply; potentially Biohazardous materials can be contained in a local area. The pump is turned on and off automatically on demand when using the VHCPRO which further reduces the noise level. An easy-to-clean touch panel adjusts and indicates the vacuum level switch point. This provides exactly the aspiration power you need ,when you need it. Available with either a 4 liter polypropylene, or 2 liter disinfectant-resistant "G" version with glass bottle.
Professional. The top-of-the-line BVC Professional adds a liquid level sensor outside the bottle, without contacting bottle contents. This lets you concentrate fully on your work without worrying about overflow. A special disinfection program allows the aspiration of disinfectant after the system is shut down to decontaminate the VHCPRO. The 4 liter polypropylene bottle version is supplied with quick connectors as standard; the 2 liter glass bottle "G"” version includes hose barb connections; optional quick connectors are available. The contact free design of the level sensor simplifies container design and reduces costs when using multiple collection bottles.
