Summary on Crystal Imaging equipment
First, I would like to point out that the replies I received do not
amount to a representative survey that would accurately reflect the
performance of the instruments mentioned. Not all users of crystal
imaging system users read the BB, disappointed users may be more
likely to respond and their testimony might reflect out-of-date
versions, happy users may not have the time or inclination to express
their views (they are probably busy mounting their crystals), and
most replies reported on specific aspects of the experience a
particular user has had. (Ok - I hope this disclaimer will cover any
legal issues).
CrystalPro - (3 responses; made by Tritek, distributed by Molecular
Dimensions)
Response 1 described software as not user-friendly and indicated that
the instrument, as a result, found little use in the lab (did not
say, whether this was a recent experience).
Response 2 – described hardware problems and software bugs (since
then fixed). Image quality and brightness was described as wanting.
Response 3 – described image quality as sufficient, did not log any
specific complaints.
Rhombix Vision - (1 response, instrument longer sold, used to be
distributed by Thermo)
Response noted very good imaging quality, good reliability, no
service issues
RockImager - (4 responses, made/distributed by Formulatrix)
Favourable reviews throughout for imaging quality and reliability.
Service by company was reported as prompt and effective. Temporary
condensation problems (resolved) were mentioned in context of the 4ºC
incubator.
Crystal Farm - (1 response, made/distributed by Bruker AXS)
Response was unfavourable. Noted reliability and service issues.
Imaging quality was not described in this response.
Minstrel - (1 response, made/distributed by Rigaku)
Response described instrument as having very good image quality, easy-
to-use software, and reported no problems with the instrument (was
installed only 4 months ago).
CrysCam - (2 responses, made by Art Robbins Instruments, distributed
in Europe by Dunn Labortechnik)
Response 1 – favourable (but by admission of the author biased).
Described the instrument as simple, robust and inexpensive.
Response 2 – noted low resolution and "poor optics".
(CrysCam is a stand-alone desktop instrument w/o incubator/hotel)
