Digital block heaters with interchangeable blocks　常溫至130℃，及可更換的試管座 1~4塊

QBD and QBH block heaters build on the superior performance, high quality design and rugged reliability of the highly successful Grant QBT series, enhanced by additional firmware features.

The general purpose QBD series comprises 1, 2 and 4 block models, while the 2-block QBH2 offers higher performance for more demanding applications.

QBA analogue block heaters, with interchangeable blocks 類比式控制器

QBA series analogue block heaters present an exceptionally high quality solution at a very cost-effective price.

Two models for 1 or 2 interchangeable blocks, for applications up to 100°C.

The analogue user interface is combined with a precision thermostat, setting resolution 2°C.

Of robust construction in streamlined coolwall aluminium and chemical-resistant plastic, with an exciting contemporary design. A sloping fascia for ease of set up, with a small footprint and low profile.

• ambient + 5°C to 100°C operation
• setting resolution 2°C
• stability ± 1.0°C, uniformity ± 1.0°C
• block extraction tool included as standard for easy and safe block removal

Interchangeable blocks

Block dimensions: 140 x 50 x 63 mm
The 63mm depth ensures precision temperature control for test tube applications.
The threaded hole accommodates either the extraction tool or a thermometer.

Polycarbonate safety covers

Tough clear polycarbonate covers maintain visibility while preventing anyone from accidentally touching a hot block. They also protect against splashing and are particularly recommended for use during high temperature operation.

External temperature probe

QBEP: Pt1000 sensor encased in a stainless steel sheath, 3mm x 30mm, fitted with 350mm of cable.

Microlitre blocks for QBD2, QBH2, QBA2

Alternative double-size blocks are available for models QBD2, QBH2 and QBA2, for:

• 0.2ml tubes, strips or microplates
• standard/high temperature 96 well microtitre plates: u-well, v-well, or flat bottom

QDP-H block for 0.2ml microplates, strips or individual tubes

With 96 holes in microplate configuration, the block accommodates one 96-well plate, 8 x 12- or 12 x 8-well strips or up to 96 individual capped tubes.

A snug fit is ensured in the precision drilled wells, for excellent uniformity: ±0.3°C within tubes across the block.

QDP-FL universal block for standard 96-well plates

Accommodates the most commonly used types of 96-well microtitre plate: u-well, v-well, flat bottom, high temperature. Also suitable for cell culture plates.

Undrilled aluminium block, black anodised for efficient heat transfer; supplied complete with hinged lid.

The double layer lid creates an insulated incubation chamber for good sample uniformity, whilst the outer surface stays cool for user comfort; uniformity: ±0.5°C between wells.

An additional extraction tool is supplied with each of the QDP-H and QDP-FL blocks, for easy and safe block removal.

Block heaters with fixed microtube block　固定式微量加熱器

BTD and BTA block heaters are ideal for rapid and precise heating of microtubes, for applications up to 100°C.

The distinctive circular block holds a combination of four microtube sizes simultaneously, and rapid heat up enables swift change of application - for maximum flexibility.

The aluminium block is housed in a compact, stylish plastic moulding, which is durable, sturdy and easy-to-clean.

The digital BTD and analogue BTA offer:

• fixed circular microtube block
• capacity for 49 microtubes:
  • 24 x 1.5 ml / 2.0ml
  • 15 x 0.5 ml
  • 10 x 0.2 ml
• temperature range ambient + 5 to 100°C
• stability ± 0.1 °C
• easy and precise temperature setting
• powerful heater for fast heat-up:
  • 25°C to 100°C in just 16 minutes
  • 25°C to 37°C in just 2.5 minutes
• small footprint and compact design

Health and Safety Regulations dictate that increasing amounts of work are carried out in a fume hood or safety cabinet; block heaters provide the ideal solution to the problem of achieving accessible, contamination-free temperature control within the fume hood itself.

Block heater

• using aluminium as the temperature transfer medium, for dry heating of samples
