Products: Goniometer Bases
We now offer several base styles to meet all your needs. Unlike other available bases, our patent-pending designs tightly capture the MicroRT™ tubing to allow seamless room-temperature and low-temperature data collection.
Our B1 through B3 bases are compatible with standard cryovials, cryotools, goniometer heads and automounting hardware. Precision machined from solid 416 stainless steel, they are extremely durable.
Base style B1 is modified from the most common base style by adding a 2 mm diameter extension to capture MicroRT tubing. It can be used with any length MicroMount, MicroMesh mount or nylon loop mount.
Base B1 has the flat "ledge" used by grippers in, e.g., SSRL automounters. Base B1A has the ledge-free conical shape used by grippers in ALS-style automounters. Use base B1A at LBNL's Berkeley Center for Structural Biology, with the PXRR automounter at Brookhaven lab's NSLS, and at CHESS.
Base styles B2 and B3 are modified from standard copper post bases by tapering the copper diameter to 2 mm to capture MicroRT™ tubing. Because only a short length of tubing must be drawn past the crystal, MicroRT tubes can be more easily taken on and off than with B1 style bases.
Base B2 is designed for use with 11 mm MicroMounts and MicroMeshes and with 10 mm nylon loop mounts.
Bases B3 and B3A accept standard 19 mm MicroMounts. Base B3S accepts SPINE length MicroMounts. B3 style bases combine the
convenience of longer MicroMounts and of the copper post style base in both room temperature MicroRT
and cryocrystallography applications.
Use with magnetic cryovials available from Hampton Research
(CrystalCap vial HR4-904
or HR8-114 )
and from Molecular Dimensions
( MD7-402.)
Base B4 is our version of the IUCr standard "brass pin" style base, modified for use with MicroMounts and the MicroRT system. Unlike other 3 mm / 1/8" diameter bases, our B4 has a smaller diameter central hole to tightly capture the stainless steel pins of MicroMounts, and a 2 mm diameter extension to capture our MicroRT™ tubing. Use for both room temperature and cryocrystallography applications.
