Fully Automated Analyzer
For erythrocyte sedimentation rate testing
The iSed system from Alcor Scientific Inc, Smithfield, RI, provides fully automated erythrocyte sedimentation rate testing, delivering accurate results in 20 seconds. Using a blood sample of 100 uL, the system is particularly suited for pediatric and geriatric patients. The analyzer tests samples directly from standard ethylene diamine tetraacetic acid tubes, reducing testing costs as well as contaminated waste. In a controlled environment, quantitative photometry measures the formation of red cell aggregates in the most critical phase of red cell sedimentation. As a result, the patient’s inflammation status is reflected accurately, unaffected by variables such as mixing and temperature. With closed-tube sampling and no required disposables, the system aims to streamline processes and improve safety for clinical laboratorians. Random-access, continuous-feed operation enables throughput of up to 180 samples per hour.

Electronically Commutated Motor
Sports a flange size of 42 mm
For laboratory automation applications with size limitations, Nanotec Electronic Inc, Medford, Mass, has developed the PD2-C, an electronically commutated motor with an integrated motor controller and encoder, and a flange size of 42 mm. It is available as a stepper motor with an operating voltage of 12-48 V and a nominal torque of 0.5 Nm, as well as a brushless DC (BLDC) motor with a nominal output of 105 W and a peak output of up to 315 W. A field-oriented controller causes the stepper motor to behave like a high-pole DC servo, with a higher torque but lower nominal speed than a BLDC motor. As a result, many applications can be realized without gearing. The motor controller can be purchased as a standalone unit with a USB connection, with its motors actuated either via clock-direction or by a set value specified on the analog input. The controller also comes in a CANopen version, where motors are actuated via field bus according to the CAN in Automation standard CiA 402. Both versions support application programs executed directly in the motor controller.

Duplex Metering Pumps
Serve as valveless alternative
The STH and STQ duplex metering pumps from Fluid Metering Inc, Syosset, NY, are designed for precision mixing, diluting, and proportional metering in original equipment manufacturer medical and analytical instrumentation. Consisting of two valveless pump heads directly coupled to a single variable stepper motor drive, the pumps serve as an alternative to conventional syringe pumps, which require multiple syringes, valves, actuators, and drivers. The displacement of each pump head is independently adjustable. In addition, a variety of pump head sizes can be used together to provide dispensing ratios from 1:1 up to 500:1, in units from microliters to liters. Using the company’s CeramPump valveless piston pumping technology, a sapphire-hard ceramic piston represents the only moving part in the fluid path, performing both pumping and valving functions. The pumps provide continuous fluid dispensing and metering during maintenance-free cycles, within 1% precision, without recalibration. Unlike syringe pump designs that fill and dispense through the same single port, the pumps offer unidirectional continuous flow, increasing throughput by utilizing two separate ports for input and output.

Pipette Tip Packaging
Offers stackable boxes for limited lab space
Sartorius Corp, Bohemia, NY, has introduced the FlexiBulk concept for packaging pipette tips. Compared with conventional bulk tip packages, stackable FlexiBulk boxes occupy less space and cut packaging waste, reducing laboratories’ transportation costs and carbon footprints. Providing quick “pick and place” convenience for loading tips into tip racks or attaching directly to pipettes, the FlexiBulk system produces significant time savings over randomly packed bulk packages. Tips are certified as free of RNase, DNase, and endotoxins. They are produced and packaged under International Organization for Standardization class 8 cleanroom conditions, and their manufacturing process is fully automated, therefore reducing the potential for contamination. Additionally, the lid of the FlexiBulk box holds an airtight seal, ensuring cleanliness of the tips during transportation and storage. The compact boxes, which are made of recyclable, durable polyethylene material, can be stacked, without the need for outer cardboard boxes. Tips in FlexiBulk packs fit Sartorius pipettes, as well as most other pipette brands. The FlexiBulk packs cover a tip volume range from 0.5 ?l to 1,200 ?l.

Group B Strep Test
Capable of lowplex and multiplex targets
Great Basin Scientific Inc, Salt Lake City, has released a group B Streptococcus (GBS) molecular diagnostic test. Providing accurate results in approximately 90 minutes with a specimen from enriched Lim broth, Great Basin’s molecular assay targets a highly conserved region of the CAMP factor gene cfb. Targeting the region leads to definitive identification and a faster diagnosis of the mother’s GBS colonization status when compared to standard culture-based testing, which may take up to an additional 48 hours. As a result, the new GBS test enables physicians to make timely therapeutic decisions to prevent the spread of the disease to the infant during delivery. Capable of both lowplex and multiplex targets, Great Basin’s integrated cartridge system enables providers to diagnose and define a clear treatment path sooner for improved patient outcomes, shorter hospital stays, and significant cost savings.

Multiplexed PCR Assay
Quantifies absolute copy numbers of genomic DNA
The Quantidex DNA assay from Asuragen, Austin, Tex, is a multiplexed quantitative polymerase chain reaction (PCR) assay that measures the absolute copy number of PCR-amplifiable DNA in a sample and reports PCR inhibition. The assay determines the functional quality of sample DNA using a quantitative functional index (QFI) score, designating the fraction of total genomic DNA copies that can be successfully amplified. Together, the QFI score and amplifiable copy number provide actionable guidance that informs the input requirements for next-generation sequencing target enrichment and helps ensure a high level of analytical sensitivity and specificity. In addition, the assay flags PCR inhibitors in the sample and provides an opportunity to salvage such samples through a subsequent cleanup step prior to further processing.
