Mixing With Pins and an Orbital Shaker


The ultimate method for mixing compounds in microplates is to use a plate on an orbital shaker while the pins are going into wells.  It is like stirring a tall glass with swizzle stick only you are moving the glass not the swizzle stick. Joerg Dreessen demonstrated the utility of this technique at the 2004 SBS meeting.  This method is especially useful when dispensing DMSO to an aqueous recipient plate as the DMSO has a greater specific gravity than water and will fall to the bottom of the wells, where it may have a toxic effect on cells growing there.  Many investigators comment that Orbital Shakers by themselves do not provide adequate mixing in 384 square plates.  Putting equivalent of a swizzle stick into each well and shaking completely overcomes that problem.

We offer both 384 (VP 324)and 1,536 (VP 326) H+P orbital shakers.  We recommend you use the VP 324 on 96 well microplates and the VP 326 on 384 well microplates.


Heating Block Compatible


Designed to meet the high temperature requirements of scientists to heat plates on a robot deck.  The "cut away" low profile design allows the robot plate handler to move the plates around the deck between multiple heating stations and cooling stations.


96/384 Plate Reformattor


VP 381O is simple registration device that allows the researcher to reformat plates from 96 to 384 or the reverse using a 96 Pin Tool.  The reformattor has a SBS footprint on the bottom that fits into a deck station.  When a 384 well microplate is placed on 1 of the 4 positions of the Reformattor, the 96 pin tool will be aligned to the same relative quadrant of the microplate.  The entire 384 well microplate is addressed when the 384 well microplate is manually moved between the 4 positions


  Registration Plates (96, 384, 1536)


V&P Scientifics' new Society of Biomolecular Screening (SBS) Registration Plates, VP 903R-96, VP 903R-384 and VP 903R-1,536 conform to the SBS specifications on plate dimensions (127.76 mm by 85.47 mm) and location of the corner wells.  We have placed a 1 mm diameter white spot in all 4 corner well positions to facilitate the alignment of Pin Tools, pipet tips, aspiration and dispensed manifolds in robots and jigs.  This spot is small enough and yet easy to distinguish for precise alignment.  But best of all, these registration plates are only a fraction of what the large robotics companies will charge you.

The photo to the right illustrates the 4 corner registration marks with arrows.

With the advent of 384 and 1,536 well microplates, the demand for accurate placement of Pin Tools, pipet tips, aspiration and dispense manifolds has increased.  Just using a microplate as the registration target is not precise enough.  We have also encountered a number of the older robotic systems such as the Carl Creative Systems, Beckman MultiMek, Sagian MultiPette, Plate Trak,  Mini Trak, Molecular Devices FLIPPER and even the Tecan TeMO that were not rotationally true when converted to 1536 Pin Tool applications.  These systems needed rotationally adjustable mounting plates.  Furthermore these registration target plates are indispensable for making these rotational adjustments.



  Pin Tool Dryer


VP 904

The Pin Tool Dryer can be located in any deck position using the SBS locating feature (VP 581B) on the bottom of the Dryer.
The arrow in the photo to the right demonstrates the activation switch.  When the bottom float plate of the Pin Tool depresses the switch, the fan is turned on and dries the pins.  When the Pin Tool is removed the fan is turned off.
The VP 581B SBS locating feature on the bottom of the Pin Tool Dryer is illustrated in the photo to the right.
The photo to the right shows the VP 904 being used on an Apricot Designs TPS-384 Robot.

VP 904-1

  Another version of our Pin Tool Dryer is available for use on robotic decks with less room between deck positions. VP 904-1 includes the SBS locating feature (VP 581B) offset 5mm from center so that it can extend slightly off the back or side. The VP 904-1 was first developed for the Agilent Bravo and is another example how V&P easily modifies existing products to meet specific needs.
