BenchTop Manifold Freeze Dryers

The BenchTop Manifold Freeze Dryer:

Advanced Microprocessor Controls
Manifold Dryer with 6 or 12 Ports
2 Liters in 24 hours
Internal Condensing Coil – 316L Stainless Steel
-48C or –85C Condenser Temperature
316L Construction
CFC-free Refrigeration
Hot Gas Defrost

Millrock has responded to customer demand for a cost effective high performance bench-top manifold freeze dryer. Our BenchTop Manifold Freeze Dryer Series takes a market proven design and has added the most advanced microprocessor control available on a bench-top unit.

The BenchTop Manifold Freeze Dryer Series boasts a 2L per 24 hour condensing rate. For water based samples, the –48 C condenser is the perfect choice. For samples containing solvents or with low eutectic points, the –85 C condenser provides maximum performance.

For labs that need quick turn-around, hot gas defrost supplies fast/automatic defrosting.

Pick from either a 6 or 12 port manifold. Both provide ample space for small and large samples to be dried simultaneously. Straight-thru vacuum valves offer a more direct vapor path.

3Gen Microprocessor Controls

Millrock has taken bench-top freeze-drying to a new level with the new 3Gen control system. Millrock’s team first developed features like the “ready” indicator and auto-power-outage recovery, and we now bring you “3rd Generation” controls with a display that is easy to read and intuitive.

With a back lit display and industrial tested microprocessor, freeze drying has never been easier. Display parameters include vacuum, condenser temperature, run time, ambient temperature, and even displays when to maintain your vacuum pump oil.

Inside the control is a new level of data acquisition that provides more accurate readings so that better control decisions can be made.

Optional Advanced I/O provides a data port for external data collection or direct printing to a printer.

BenchTop Manifold Freeze Dryer Features

Manifold

A 6 or 12 port manifold is provided with the Benchtop Series dryer and comes complete with vacuum valves. Each port is 1/2” external diameter. The ports are spaced to provide room for the largest flasks.

Vacuum Valves

The straight-thru design of Millrock valves provide less flow restriction and have greater internal diameter than other 3/4” diameter valves. The end result is faster, more consistent drying.

Vacuum Pump

A 60 Lpm vacuum pump is recommended.
