pylabrobot.kbiosystems.sealer.KBiosystemsSealer#

class pylabrobot.kbiosystems.sealer.KBiosystemsSealer(port: str, timeout: float = 5.0, settle_time: float = 5.0, preheating_temperature: int = 100, offline_temperature: int = 20)#

Bases: ABC

Shared base for KBiosystems serial heat sealers (Ultraseal ePRO / XT Pro).

Every model speaks the same ASCII-over-RS-232 core: a command is written with a CR terminator, the device echoes the command in front of its reply, and the echo is stripped before the reply is parsed (e.g. A160 -> A160ok -> ok; ? -> ?3f -> 3f). A reply containing syntax means the command was rejected. This base implements the transport, the status/error polling state machine, and the temperature and time commands shared by all models. Subclasses supply the model-specific status flags, error table, temperature limits, human-readable name, setup, seal, and any extra commands.

Serial settings: 9600 baud, 8 data bits, no parity, 1 stop bit, no handshake, CR (\r) terminator.

Methods

__init__(port[, timeout, settle_time, ...])

request_error_code()

Read the current error code (E).

request_sealing_temperature()

Read the sealing temperature setpoint in degrees C (C).

request_sealing_time()

Read the sealing time setpoint in seconds (D).

request_status()

Read the status byte (?).

request_temperature()

Read the current heater temperature in degrees C (F).

seal(temperature, duration)

Seal a plate at the given sealing temperature (C) and duration (s).

send_command(command[, read_reply])

Send a command and return the reply with the echoed command stripped.

set_sealing_time(seconds)

Set the sealing time in seconds (B).

set_temperature(temperature)

Set the sealing temperature in degrees C (A).

setup()

Open the connection and bring the sealer to a ready, pre-heated state.

stop()

Return the heater to the offline temperature and close the port.

wait_for_idle([ignore_mask])

Wait until the device is Ready, tolerating the bits set in ignore_mask.

wait_for_sealing_temperature([timeout])

Block until the heater reaches the setpoint (NotAtSealTemperature clears).
Parameters:

  • port (str)

  • timeout (float)

  • settle_time (float)

  • preheating_temperature (int)

  • offline_temperature (int)
