Hoefer® Gel Casters

 

Enable several gradient or homogeneous gels to be cast simultaneously. Choice of multiple-gel casters or dual-gel casters.

 

Gel Casters for Small Format Vertical Electrophoresis Systems (SE250, SE260, SE300)

 

Multiple-Gel Casters

  • Pour uniform gels from the top; pump gradient gels into an inlet port at the bottom of the unit
  • Sandwiches fill at the same time and at the same rate from the same solution
  • The result: identical gels
  • Glass plate sandwiches seal leak-free without the use of messy grease or tape
  • Once cast, gels can be wrapped in plastic and refrigerated for several weeks

Dual-Gel Caster (SE245)

  • Cast one or two gels
  • Accommodates both 10 x 8 cm and 10 x 10.5 cm plates

*For use with the SE250 and SE260 Series only.

Gel Casters for SE600 and SE400 Series Vertical Units (SE600, SE400)   


Multiple-Gel Casters

  • SE675 casts up to four 16 cm long gels
  • SE615 casts up to ten 16 cm long gels
  • Easy to use and leak-free
  • Cast homogeneous or gradient gels. Pour homogeneous gels directly into the top of the casting chamber: pump gradient gels through an inlet port at the bottom

Dual-Gel Caster (SE6015)

 

SE6015 Dual Gel Caster is included when you order an SE600 series unit. It can also be ordered separately.

  • Casts two 8, 16, or 24 cm long gels at a time
  • Double the capacity with optional divider plates
  • Easy to use and leak-free
  • Glass Sandwichers seal into the casting 

*For use with the SE600 Series only.

Hoefer® Mighty Small Precast Gels

 

Hoefer® Mighty Small precast gels are high-performance mini polyacrylamide gels commonly used for protein separation. Utilizing the Bis-Tris buffer system, they effectively minimize protein modifications during electrophoresis, resulting in sharper and clearer protein bands with higher resolution.

  • High loading capacity: 50 uL max. sample volume
  • High resolution: Upgraded bis-Tris system for clearer, sharper separation bands and higher resolution
  • Ready to use and easy to store: No solution preparation or gel casting is required, saving time. Store at 2 to 8ºC
  • Good Repeatability: Fully automated gel casting process, minimal batch-to-batch variation, high stability, and good repeatability
  • Highly effective: Max 40 min for electrophoresis
  • Safe and non-toxic: No hazardous reagents need to be handled 

Compatible with Hoefer® Mighty Small II Vertical Electrophoresis Systems and the Hoefer® miniVE Vertical Protein Electrophoresis and Blotting Systems.

Hoefer® Standard and Preparative Combs for Vertical Systems

 

Combs are precision machined from Teflon®, which is highly resistant to acids, bases, and all commonly used buffer systems. An important benefit of Teflon® combs, compared to other types, is that they are easily removed while maintaining gel integrity. They are lightweight and virtually unbreakable when used with reasonable care. Some combs have microtiter spacing for use with multi-channel pipettes.

  • Standard Combs come attached to a standard back, which produces maximum well depths of 25 mm, except for the 28-well combs, which produce well depths of 15 mm. 15-well Standard Combs have microtiter spacing for use with multichannel pipettes.
  • Preparative Combs have adjustable comb backs (10, 15, and 25 mm depth) and form 1 large preparative well plus 1 or 2 small reference wells.
