The Scientemp 34-09A is a 9 cu ft chest freezer from Scientemp's Moderate Cold (-30 °C) line, holding a working range of 0 °C to -34 °C (-30 °F). It pairs a Love digital temperature controller, a key-locking counter-balanced lid and 4 locking casters with welded-steel construction and CFC-free R-404A refrigeration - an economical, reach-in chest freezer for routine laboratory cold storage.

Application Profile
At 0 °C to -34 °C (-30 °F), the Scientemp 34-09A sits in the *moderate-cold* band - colder than a -20 °C lab freezer but above the ultra-low range - where the science calls for reliable frozen storage rather than deep cryopreservation. Typical loads are bulk reagents, enzymes, control samples, environmental and food specimens, and general biological material that keeps well at -30 °C. The 9 cu ft chest format trades floor space for capacity: a horizontal cabinet holds cold better than an upright when the lid is opened, because cold air (being denser) settles rather than spilling out - a real advantage for temperature stability during loading (see cold-storage).
Chest geometry favors *archival* storage - items you add and retrieve in batches - over high-frequency reach-in access. The Love digital controller displays internal temperature in °C or °F and an audible alarm warns of a temperature rise, though this line carries no battery backup, so pair it with facility monitoring for GxP or clinical duty. For deeper set-points, step up to the Super Cold (-40/-45 °C) or Ultra Cold (-80/-86 °C) lines (see low-temperature-freezer-selection).
Frequently Asked Questions
What temperature does the Scientemp 34-09A reach?
Its working range is 0 °C to -34 °C (-30 °F). It is part of the Moderate Cold (-30 °C) line.
How much can it hold?
The 34-09A has a 9 cu ft interior measuring 26.5"H x 32.25"W x 18.5"D. Exterior dimensions are 35"H x 37"W x 26"D.
What voltage options are available?
This SKU is configured for 115 V / 60 Hz, single phase. Factory voltage options are: 115 V / 60 Hz (this model is single-voltage per the 34-09 spec table). Match the model to your facility's supply before ordering.
Is defrost automatic?
No - like all Scientemp chest freezers, the 34-09A uses manual defrost with a cold-wall evaporator, which avoids the temperature swings of an auto-defrost cycle for stable long-term storage.
Can it be customized?
Yes. Listed accessories/upgrades include cryo-gloves, a CAL9500 ramp/soak controller upgrade, CALgrafix software, a chart recorder and an automatic voice pager dialer; some options require adding an end rack.
Ordering & Configuration
The Scientemp 34-09A is built-to-order laboratory refrigeration; request a quote to confirm configuration and pricing. At quote, verify: set-point vs. the coldest material you store, capacity against your sample volume, voltage/electrical supply, any options (access ports, ramp/soak, CO2/LN2 back-up, stainless interior, monitoring), and freight/lead time for a unit of this size and weight.
Warranty: Per Scientemp standard terms - confirm at quote.
Positioning: the Scientemp 34-09A is a 9 cu ft Moderate Cold (-30 °C) chest freezer - economical frozen storage for reagents and biological samples that keep at -30 °C. Step up to the Super Cold (-40/-45 °C) line for deeper set-points, or the Ultra Cold (-80/-86 °C) line for biobank-grade preservation.
