Programmable Chilling Incubators Increase Protein Crystalisation Success Rates
Torrey Pines Scientific announces its EchoTherm™ Programmable, Vibration Free Chilling Incubators to improve the rates of success for protein crystallisations.
The incubators can be programmed to vary temperatures precisely from one set point to another repeatedly in a programmed routine thus increasing the success rates of protein crystallisations. The oscillations in temperatures from one point to another have been shown to create favourable crystallisation pathways.
Temperatures are settable from 4.0°C to 70.0°C. The units are Peltier-based for heating and chilling. They have no compressors or CFC’s and are vibration-free making them ideal for doing protein crystallisations.
There are three programmable models with chamber sizes of 27.5 litre, 55.0 litre or 100 litre. They are settable to 0.1°C from 4.0° to 70.0°C and are accurate to ± 0.1°C. Three programs can be held in memory with 10-steps per program. All programs can be made to repeat from 1 to 99 times or infinitely, if wanted.
The 27.5 litre unit’s chamber is 12” high by 10” deep by 14” wide and comes with two stainless steel racks with room for four. The 55.0 litre unit’s chamber is 24” high by 10” deep x 14” wide and comes with four stainless steel racks with room for six, and the 100 litre model has a chamber 24” high by 20” deep x 14” wide and comes with 4 racks with room for six.
The units are shipped with universal power supplies that take AC line inputs from 100VAC to
265VAC, 50/60 Hz and converts that to 12 volts DC for the units, AC line cord for the country of use, user’s manual and full 12-month warranty. They are UL, CSA, and CE compliant.

In-Depth Viscosity Measurement Training from Brookfield
Brookfield Engineering, the world standard for viscosity measurement and control, offers its Practical Course on Viscosity Measurements. This popular course is designed to help Brookfield viscometer users comprehend the functionality of their instrument, solve the mysteries of fluid behaviour and Rheology, and create successful and repeatable viscosity test methods for use in both R&D and QA/QC environments. Consistent measurement is vital in the success of any product and understanding viscosity is a key part to maintaining quality control.
The course is offered at Brookfield’s headquarters in Middleboro, MA and at major cities across the United States. Space is limited and customers are encouraged to sign up early. ‘On-Demand’ courses are conducted at the customers’ facilities or at Brookfield’s headquarters. An advanced course, Lab Day/Advanced Viscosity Test Methods is an on demand course covering more advanced viscosity topics utilising sample testing.
‘Practical Course on Viscosity Measurements’ is Brookfield’s most popular course. A one-day course designed to help you get the most out of your Brookfield Viscometer and Rheometer measurements by providing you with information, activities and techniques that you can easily understand and immediately put to practical use. Discussion topics include how to pick a spindle/ speed combination, methodology, rheology, calibration and verification checks. It is designed for beginner to intermediate users.
‘Lab Day/Advanced Viscosity Test Methods’ - This is an ‘on demand’ course offering. To schedule a class either at your facility or at the Middleboro location, please call Brookfield at 800-628-8139. This is a one-day, advanced course that focuses on the customer’s interests, formulations and processing problems. The course covers viscosity and related rheological measurements including: yield stress, shear rate ramps, viscosity vs. temperature profiles, creep and viscoelastic behaviour. This course is offered at the facility in Middleboro or at the customer’s location and is designed for the intermediate to advanced users.
