Benchmark™ IsoBlock™ Dry Bath

 

The IsoBlock™ model from Benchmark™ contains two isolated block chambers. Each chamber is controlled independently, allowing the dry bath to serve as two dry baths in one. The hinged (and removable) lid is designed with a dividing wall; when the lid is closed, this dividing wall acts as a barrier, preventing air transfer between chambers. The control panel features large digital displays of both time and temperature. Any any point, either setting of a block can be adjusted, without affecting the settings of the other block.

A wide variety of blocks are available for accommodating nearly all popular tube sizes. In addition, the unique Quick-Flip™ universal blocks accept tubes from 0.5 to 2 mL and with just a quick flip to the other side, accommodate 0.2 mL tubes or PCR strips.

SHEL LAB Shaking Water Bath

SHEL LAB Reciprocating Water Baths deliver precise temperature control and a smooth reciprocal shaking motion. Temperature and oscillation controls feature an easy to read P.I.D. microprocessor temperature controller and an independent safety thermostat. 

The bath may be used with or without oscillation. Shaking speed is variable from 20 to 200 oscillations per minute, and the stroke length can be adjusted to three separate settings: 0.5, 1.0, or 1.5 inches to minimize the chance of accidental spillage. Also, the unique basket support system is designed to eliminate tank wear, yet still provide full support and free action for a heavily loaded basket. 

A durable finish on the housing prevents corrosion and chipping. In addition to a stainless steel tank, the bath platform tray is designed for optimum temperature uniformity. Maximum temperature is achieved using the stainless steel gable cover, which is designed to prevent condensate from dripping onto samples and assures uniform temperature conditions. These units feature:

  • Microprocessor Control
  • Independent Oscillation and Temperature Controls
  • Recessed Heating Element to Prevent Burnout
  • Adjustable Stroke Length
  • Great for heat inactivating FBS
  • 2 year limited warranty, excludes tank
