Alpha Innotech FlourChem IS-8900
The equipment can be used for a wide array of quantitative imaging applications ranging from chemi-luminescence imaging, fluorescence imaging, gel, film and membrane imaging to culture and microplate-based assays.
|Corbett Research RG 3000||
The Corbett Research RG 3000 is a reliable thermal cycler, allowing researchers to perform PCR reactions quickly while also giving them the ability to monitor the reaction in real-time. The cycler holds either 36-0.2 ml or 72-0.1 ml standard PCR tubes and it is an open chemistry platform. The open chemistry platform uses multiple excitation sources (470, 530, 585 and 625 nm LED high power diodes) combined with several detection filters (510, 555 and 610 nm bandpass and 665, 570 and 610 nm high-pass) to detect virtually every known fluorophore (Sybr-Green I, FAM, TET, JOE, VIC, HEX, ROX, TAMRA, CY3, CY3.5, CY5, CY5.5, Oregon Green, CAL Red, Red 640 and Texas Red). Also, most DNA amplification enzymes/ buffers can be used. The system comes with data analysis software. The main advantage of the RG3000 is the flexibility and the low running cost of the cycler. The reaction vessels are standard PCR tubes and no expensive kits have to be used.

The New Brunswick Scientific Innova 4300 Large Capacity Incubator Shaker is designed for handling greater quantities of flasks. It easily holds (12) 2 L flasks and accepts flasks up to 6 L. The Innova 4300 shaker incorporates a triple eccentric counterbalanced drive to provide horizontal plane rotary motion in a 1 in. (25.4 mm) circular orbit. A Proportional/Integral (PI) Microprocessor controller with instantaneous digital feedback controls the speed over a range of 25-500 RPM. It also provides temperature control over a range of 5°C above ambient to 60°C. The internal chamber is 34¾ inches (88.3 cm) wide, 22¼ inches (56.6 cm) deep, 19¼ inches (48.9 cm) above the platform and will accept flasks up to 6 liters.

New users need to sign yearly contract and participate in yearly costs to maintain facility (approximately on average $700-800/year). The costs are intended to offset anticipated repairs and service contracts, to maintain the lab and equipment in good order.
MGU is located in Western Science Center WSC, room 357 and it is open on weekdays from 9:00 am until 5:00 pm. During these hours, the Facility manager will be available for training and consultation regarding the instruments. The staff or student card can be registered in order to gain card access to the facility after hours. During after hours, the user will be held responsible for ensuring that doors are kept locked at all times.
Responsibilities of Users and their Supervisors
Users must be trained by the Facility staff to ensure safe usage of the equipment. Log books are provided for each instrument and users are expected to log in their time of usage. When the work is complete, the user should ensure that the work area is left clean. Any problems or concerns can be noted in the log books or the user can contact the Facility manager. In the event of instrument damage due to abuse, misuse, or unauthorized use, the research supervisor will be held financially responsible for the cost of repair or replacement.
The facility will charge fees in order to cover the cost of consumables and instrument operating costs as defined in the fee section. Users must provide a valid speed-code or account number for invoicing.
