Samdri® PVT-3D manual critical point dryer
Manual critical point dryer with advanced auto-pressure and temperature control
SAMDRI®-PVT-3D gives high precision results using manual controls. Four micro-metering valves are conveniently located on top of the critical point dryer for ease of operator control. Integrated automatic critical point temperature control and pressure regulation are included as standard – avoiding the need for an external source of heating and cooling. Automatic safety controls are standard features within the SAMDRI®-PVT-3D.
The chamber has an internal diameter of 31.75mm and a depth of 31.75mm.
There is a wide selection of specimen holders to suit most specimen types – please see below for details.
- Compact, lightweight tabletop size with small footprint
- Precise flow control for inlet, cooling, purging, venting and bleed micro-metering valves
- Vernier metering valves – reproducible process settings
- Internal surfaces inert to LCO2 and ultra-pure alcohols
- Integrated automatic temperature control
- Static pressure control module – automatic pressure stability
- Top-mounted valves – easy loading/unloading of process chamber
- Internal filtration – protects specimens and valves down to 0.5µm
- Bottom-lit chamber with viewing port – aids visualisation of chamber and specimens
- Fast adiabatic chamber cooling with CO2
- Safe operation – fitted with rupture disk (activates @ 2000 psi) and pressure relief valve (activates @ 1250-1350 PSI)
- Optional SOTER™ condenser – captures waste alcohol and reduces exhaust noise

Opening size: 0.3mm
Approximate outer dimensions: 25.4mm Ø, 28.6mm H

8766 and 8767 cover slip holders
8766 (right image). Designed to hold and process up to ten 9mm to 13mm diameter glass cover slips.
Approximate outer dimmensions: 16mm Ø, 25.4mm H
8767 (left image). Designed to hold and process up to ten 16mm to 22mm diameter glass cover slips.
Approximate outer dimmensions: 25.4mm Ø, 25.4mm H


PVT-3D options
SOTER™ condenser
This option quietly separates waste alcohol from the carbon dioxide exhaust discharge from the PVD-3D process chamber.
Includes 375mm carboy exhaust tubing, 250mm condenser exhaust tubing, 75mm clear drain tubing and exhaust connection.
Dimensions: (W x D x H): 355mm x 178mm x 457mm

LCO2 cylinder scales with remote display
Liquid carbon dioxide cylinder (tank) scale with remote LCD readout display. Critical point drying requires liquid carbon dioxide (not gas) and the cylinder will have a draw tubes rather than a two stage regulator.
Using this option is the best way to monitor LCO2 consumption, which is based on cylinder weight and not pressure. 400lb capacity. Reads either Lb or Kg
