Pins, Caps, and Vials for LS-CAT

Pins

LS-CAT supports 18mm pins for both robotic and manual mounting. This results in a distance of 22mm from the bottom of the base to the sample.

Critical: If pins are too long or short, your sample cannot be positioned in the cryostream or the X-ray beam.

Manual only. Always crashes cryotong gripper.

Plastic Screw Caps

Zero robot support. Significant risk of sample loss.

Container Rules: "GOOD" caps work in both SPINE Baskets and ACTOR Magazines. Note that Vials are required in SPINE Baskets and forbidden in ACTOR Magazines.

Magnetism & Maintenance

We rely on magnetic properties for mounting. Caps with weak or reversed magnetism will cause samples to fall during transfer.

Pro Tip: Always remove rusty or damaged caps from service immediately to prevent robot failures.

Vials (SPINE Robotic Changer)

Good Bad (Inconsistent) Bad (Non-SPINE)
MD Magnetic Vials (MD7-402)

Mitegen SPINE vials are also currently supported.

Hampton SPINE Vials

Size is too inconsistent for automation.

Standard Vials

Lack necessary metal components.
