Evacuable KBr Pellet Die

Evacuable KBr Pellet Die

  • Hardened stainless steel
  • Highly polished pellets
  • Evacuable for sample pellet clarity and quality
  • Use in conjunction with 15-ton hydraulic press
  • Optional vacuum pump kit for moisture free pressing
  • Make pellet from 5 mm to 40 mm diameter
15-ton Hydraulic Press

15-ton Hydraulic Press

  • The 15-ton hydraulic press is used in conjunction with the evacuable KBr pellet die to prepare high quality 13 mm die for transmission measurement
  • Polycarbonate safety guards
  • Adjustable upper bolster
  • Adjustable pressure control valve
  • Gauges for low pressure applications (0 – 1, 0 – 2, 0 – 5 tons optional)
Specadie Kit

Specadie Kit

The Specadie allows you to prepare KBr pellet of 8.5 mm diameter without the hydraulic press.

Omni-cell

Omni-cell

The Omni cell is available in sealed and demountable types. The demoutable type is used for general purpose and the sealed type is used for volatile and low viscosity liquids. Both types of liquid cells are suitable for quantitative analysis.

Key features

  • Various windows are available such as NaCl, KBr, CaF2, BaF2, ZnSe, KRS-5, CsI, CsBr and Silica
  • Pathlength from 0.025 mm to 1.00 mm
Micro Mull Cell

Micro Mull Cell

The mull cell does not have the standard liquid filling port. The sample is placed directly onto one of the circular window and the other window is then placed on top.

It is suitable for high viscosity liquids, gels and pastes, oil and grease as well as solids suspended as mulls.

Variable pathlength liquid cell

Variable pathlength liquid cell

  • Continuous adjustment of sample pathlength
  • Micrometer and vernier scales for accurate pathlength setting and readability
  • Standard 3" x 2" slide mounting
  • Pathlength variation: 0.04 to 6 mm
  • Scale division: 5 mm
  • Volume at maximum pathlength: 6 mL
  • Available in NaCl, KBr, CaF2, BaF2, CSi, CsBr, KRS-5, fused silica, AgBr, polyethylene, ZnSe and silicon windows
Short pathlength gas cell

Short pathlength gas cell

These 10 cm pathlength gas cells are ideal for analysing gases and vapour at room temperature and low pressure

Key features

  • Available in Pyrex or stainless steel body
  • Choice of windows: NaCl, KBr, CaF2, BaF2 and ZnSe
  • A heated version is also available with temperature range from ambient to 250 °C
Long pathlength gas cell

Long pathlength gas cell

Long pathelength gas cells are suitable for measuring low concentration gases and gases for environmental applications. Two series of gas cells are available i.e. Cyclone (fixed or variable pathlength) and Tornado (fixed pathlength only)

Key features

  • Selection of KBr, ZnSe and CaF2 windows
  • Optional heated version from ambient to 200 oC
  • Cyclone C2: fixed or variable pathlength from 0.5 m to 2.5 m (in 0.5-m step)
  • Cyclone C5: fixed or variable pathlength from 1.0 m to 8.0 m (in 1-m step)
  • Cyclone C10: fixed or variable pathlength from 2.1 m to 10.6 m (in 1.06-m step)
  • Tornado T5: fixed pathlength gas cell (maximum 8 m)
  • Tornado T10: fixed pathlength gas cell (maximum 10.6 m)
  • Tornado T20: fixed pathlength gas cell (maximum 20 m)
