Improve Accurate Liquid Additions While Reducing Fatigue and Errors
EZ View Microplate Stand (HS 1997) Manual pipetting biological and hazardous samples into a microplate is safely carried out inside a hood. While laying flat on the surface of a hood, the microplate needs to be examined carefully by frequent viewing of emptied and filled wells during liquid transfers. It is often difficult to check well menisci levels without the user needing to extend their head inside the hood in order to view the microplate from directly above. The EZ View Microplate Stand is designed to allow the microplate to be tilted and viewed at a comfortable angle preset by the user. The angular presentation of the plate reduces errors of liquid additions and improves accuracy.
(HS 1997)

Enhanced View Microplate Stand (HS 1996) A magnifying mirror (×2), positioned beneath a top plate (for holding samples plate), can be tilted at an angle so as to allow for easier viewing of each well (through the magnified reflected image). Especially useful in the performance of immunoassays where color changes in any well need to be quickly identified. (HS 1996)

Microplate Orientation ( 96-Well Plate Column Indexer ) (HS 60A) The Column Indexer is designed to allow liquid additions to a 96-well plate or an SPE plate (on top of a collection plate) by column through the base handler. The units are manufactured of teflon-coated aluminum to allow smooth stepwise movement of the base handler. Easily return to whichever column you were working in - after any pause or interruption. Never lose your place again. (HS 60A)

LightOne™ Illuminator (HS 60B) LightOne Illuminator is a compact, bench top pipetting aid for enhanced visualization of 96 well plates. It provides illumination of specific wells during dispensing, and as a stand-alone device, requires no computer interface. The illumination may be advanced manually or automatically with a user-defined time interval - with a convenient pause feature included. LightOne Illuminator reduces errors associated with manual pipetting into 96 well plates, and increases the confidence of the operator in delivering the correct reagent or sample to the intended well.

Find Mixing and Centrifuging Samples Time Consuming and Fatiguing? Why Not Use the Following Tools to Accomplish Both Tasks Efficiently?
EZ 16 Tube Centrifuge Racks (HS 1999)	EZ Sample Preparer (HS 01)

Both tools shown above are designed to allow fast mixing and centrifuging prior to high throughput robotic or manual pipetting of biological samples from test tubes (10-13mm o.d.) to a 96-well plate. Each tool consists of a carrier with two handles and six square-shaped racks in a 4 × 4 format. The difference between these two tools is the size of each 4 × 4 rack. EZ 16 Tube Centrifuge Racks will fit into a larger centrifuge bucket whereas the EZ Sample Preparer will fit into a 96-well plate centrifuge. The errors caused by fatigue and/or operator mistake during the sample mixing and centrifugation procedures can be eliminated by using this well indexed and marked organizer. Equal spacing between the same rack or the adjacent racks permit the utilization of any robotic workstation equipped with either 4- or 8-channel probes. They are manufactured of aluminum to allow vigorous vortex-mixing, and liquid level sensibility of any robotic liquid handling system. An electronic pipettor with expandable 8-channel disposable tips can also be used to transfer biological samples inside tubes or vials to a 96-well plate.

(HS 1999; HS 01)

EZ 48 Tube Centrifuge Racks (HS 22)

Consisting of two aluminum racks in a 4 × 12 format, EZ 48 Tube Centrifuge Racks are designed to organize and expedite (96) biological sample centrifugation using 96 tubes/vials (8-12mm o.d.) prior to robotic or manual pipetting. Errors caused by fatigue or operator mistake during sample centrifugation can be eliminated by using these well-indexed and marked racks. Both racks can fit into a standard centrifuge for 96-well plates - eliminating the need to use a large, floor type centrifuge. (HS 22)

96 Sample Tube-Plate Formatter (HS 1993) In combination with a 96 channel liquid handler, EZ 48 Tube Centrifuge Racks can be made in a mirror-image configuration to enable transfers of biological samples from 96 tubes to a 96-well plate without the need to change tips. Typically, transfer requires about 30 seconds. (HS 1993)
