Hardware Overview

Located at the front of the instrument, the NT8 deck contains everything needed for your dispenses including the plates, protein source, and tips.

The NT8 deck is divided into the following stations:

Note: Please refer to the NT8 hardware picture above to see the position of each station.

Waste Station

The waste station is where the NT8 disposes of low volume (LV) tips.

Protein Source Station

The protein source station stores protein sample before it is dispensed into a plate. It is included in the NT8 accessories kit. The NT8 supports both low volume (LV) and high volume (HV) protein blocks, both of which come with a sensor that helps the NT8 Control Software to automatically detect the type of protein block being installed in the hardware.

 

Protein Blocks

When you purchase NT8, two protein blocks (low volume and high volume) come prepackaged in the accessories kit. Each protein block has three columns of eight drops each (24 total). The low volume protein block is capable of holding 3 μL while high volume protein block is capable of holding 13 μL. The protein sample is stored inside a disposable protein tray that is placed on top of the protein block and is secured by a magnet clamp. See the picture below for reference.

Wash Station

The wash station is used to wash low volume pipette tips.

Low Volume (LV) Tip Caddy Station

The LV) tip caddy station is a repository that holds up to 384 replacement LV tips. Use these tips to aspirate protein sample from the protein tray.

Microplate Stations

On the NT8 deck, there are designated areas for three SBS footprint microplates. Three microplates can be placed on the deck to transfer reagents from one plate to another. A hanging drop cover sheet can be placed on station #1 for setting hanging drops.

 

Reference Plate

The NT8 accessories kit also includes a reference plate, which is useful for tuning plate station 1, 2, and 3 to get accurate dispense locations. The reference plate has a reference hole in every corner for reference points. The reference hole that is located near the A1 symbol represents well A1 on a microplate (see the picture below, indicated by orange circle).

High Volume (HV) Tip Caddy Station

The HV tip caddy station holds up to 96 replacement HV tips for the system.

Deep Well Station

The deep-well station is compatible with 96 deep-well plates, which are used in plate copy tasks.

The NT8 head contains tools for aspirating and dispensing liquids stored in the plates or trays on the NT8 deck. You can tell the NT8 to move the head forward and backward, up and down, or to the right or left.

 

What you can find on the NT8 head:

• Low Volume (LV) Tip Attachments

  Located in the bottom-left corner of the NT8's head, LV tip attachments are where you install the LV tips for use in aspiration and dispense. There are up to 8 LV tip attachments, all of which are equipped with a sensor that indicates when a tip touches the surface. Indicator lights are placed on the board that holds the LV tip attachments.

  If the tip is touching a surface, the sensor will be off; otherwise it will be bright blue, as seen in the picture below.

  

  Low Volume (LV) Tips Attachments

  Note: When you see a tip number referenced in the text, 1 is the tip closest to the back of the instrument and 8 is the one closest to the front.

• OPTIONAL: High Volume (HV) Tip Attachments

  HV tip attachments are located in the bottom-right corner of the NT8's head and are used for plate copy experiment. Each HV tip attachment is equipped with a sensor that detects contact with the liquid surface in a deep well plate. The HV tip attachment uses 200 μL pipette tips (eight at a time) to aspirate liquid from a deep well block and transfer it to a crystallization plate.

  

  High Volume (HV) Tip Attachments

• OPTIONAL: Lipidic Cubic Phase (LCP) Syringe Mount

  If your NT8 includes the LCP option, there is an LCP Syringe Mount on the front left side of the NT8 head. It is compatible with a Hamilton LCP syringe.

  

  LCP Syringe Mount

• OPTIONAL: Lipidic Cubic Phase (LCP) Lever

  Adjust the LCP Syringe Mount.

  

  LCP Lever

  Note: You can adjust the lever speed and height to fit the LCP syringe by clicking the Setup Joystick Speed button in the LCP Syringe Control panel and moving the lever button on the NT8's head up and down, as needed.
